    Crontab-like syntax

    See String format for more info about the crontab-line syntax

    This way will be very useful for cases when you need to configure something via external configuration (from file on startup or via some parameter from requests, for example):

    val schedule = \"5 * * * *\"\nval scheduler = buildSchedule(schedule)\nscheduler.asFlow().onEach {\n// this block will be called every minute at 5 seconds\n}.launchIn(someCoroutineScope)\n

    In case of usage builder (lets call it lambda way), you will be able to configure scheduler in more type-safe way:

    Start/step is a little bit more complicated syntax. It means start from the first element, repeat triggering every second element. Examples:

    Means that each minute starting from fifth second it will repeat triggering every fifteenth second: 5, 20, 35, 50.

    Every is more simple syntax and could be explained as a shortcut for 0/{int}. Example:

    "},{"location":"krontab/describing/string-format.html#just-at-the-time","title":"Just at the time","text":"

    The most simple syntax. It means, that scheduler will call triggering every time when element was reached:

    Means that each minute scheduler will call triggering at the fifteenth second.

    All the previous elements can be combined with listing. Lets just see several examples:

    You always able to create your own scheduler. In this section will be presented different ways and examples around standard CronDateTimeScheduler builders buildSchedule. You can read about schedulers in KrontabScheduler

    Currently, buildSchedule is the recommended start point for every scheduler. Usually, it is look like:

    val scheduler = buildSchedule(\"5 * * * *\")\n

    Message type notice

    On this page all the messages will be just simple String, but you may pass any object as the message

    As has been said in the setup section, this library contains next levels of logging with their default representations on each platform:

    Weight (by order) LogLevel name JS JVM Loggers Android 0 DEBUG console.log Level.FINEST Log.d 1 VERBOSE console.info Level.FINE Log.v 2 INFO console.info Level.INFO Log.i 3 WARNING console.warn Level.WARNING Log.w 4 ERROR console.error Level.SEVERE Log.e 5 ASSERT console.error Level.SEVERE Log.wtf

    Each of these levels have fullname and shortname shortcat extensions:

    And any of these shortcuts may accept one of several arguments combinations:

    So, when you want to log some expected exception, there are three common ways to do it:

    val logger = KSLog.default\n// with callback\nlogger.info(tag, throwable) {\n\"Some your message for this event\"\n}\n// with suspendable callback\nlogger.infoS(tag, throwable) {\nwithContext(Dispatchers.Default) {\n\"Some your message for this event\"\n}\n}\n// Just with message\nlogger.info(\"Some your message for this event\", throwable)\n// With message and tag as strings\nlogger.info(tag, \"Some your message for this event\", throwable)\n

    Of course, any of this calls can be shortenned:

    val logger = KSLog.default\n// with callback\nlogger.i(tag, throwable) {\n\"Some your message for this event\"\n}\n// with suspendable callback\nlogger.iS(tag, throwable) {\nwithContext(Dispatchers.Default) {\n\"Some your message for this event\"\n}\n}\n// Just with message\nlogger.i(\"Some your message for this event\", throwable)\n// With message and tag as strings\nlogger.i(tag, \"Some your message for this event\", throwable)\n

    There is special shortcat - for base performLog. In that case the only change is that you will require to pass the LogLevel more obviously:

    val logger = KSLog.default\n// with callback\nlogger.log(LogLevel.INFO, tag, throwable) {\n\"Some your message for this event\"\n}\n// with suspendable callback\nlogger.logS(LogLevel.INFO, tag, throwable) {\nwithContext(Dispatchers.Default) {\n\"Some your message for this event\"\n}\n}\n// Just with message\nlogger.log(LogLevel.INFO, \"Some your message for this event\", throwable)\n// With message and tag as strings\nlogger.log(LogLevel.INFO, tag, \"Some your message for this event\", throwable)\n

    OR

    val logger = KSLog.default\n// with callback\nlogger.l(LogLevel.INFO, tag, throwable) {\n\"Some your message for this event\"\n}\n// with suspendable callback\nlogger.lS(LogLevel.INFO, tag, throwable) {\nwithContext(Dispatchers.Default) {\n\"Some your message for this event\"\n}\n}\n// Just with message\nlogger.l(LogLevel.INFO, \"Some your message for this event\", throwable)\n// With message and tag as strings\nlogger.l(LogLevel.INFO, tag, \"Some your message for this event\", throwable)\n

    The main point in setup in your code is to setup default logger:

    You may use custom messageFormatter in any of KSLog factory to customize output of KSLog logging. For example:

    KSLog(\n\"loggingWithCustomFormat\",\nmessageFormatter = { level, tag, message, throwable ->\nprintln(\"[$level] $tag - $message: $throwable\")\n}\n)\n

    Additionally you may use one of several different settings:

    In case you are passing minLoggingLevel, the level and more important levels will be passed to logs. For example, when you are settings up your logger as in next snippet:

    val logger = KSLog(\n\"exampleTag\",\nminLoggingLevel = LogLevel.INFO\n)\n

    In the snippet above was used version 2.0.1 which is actual for TelegramBotAPI at the moment of filling this documentation (May 22 2022, TelegramBotAPI version 2.0.0) and you can update version of this dependency in case if it is outdated.

    For configuring proxy for your bot inside your program, you can use next snippet:

    val botToken = \"HERE MUST BE YOUR TOKEN\"\nval bot = telegramBot(botToken) {\nktorClientEngineFactory = OkHttp\nproxy = ProxyBuilder.socks(\"127.0.0.1\", 1080)\n}\n

    1. val botToken = \"HERE MUST BE YOUR TOKEN\" - here we are just creating variable botToken
    2. val bot = telegramBot(botToken) { - start creating bot
    3. ktorClientEngineFactory = OkHttp - setting up engine factory of our bot. On the time of documentation filling, OkHttp is one of the engines in Ktor system which supports socks proxy. More you can read on Ktor site in subparts about engines and proxy

    The base version of library was done a lot of time ago and just got several additions related to improvements, updates in Telegram Bot API or some requests from our community.

    There are several important things in context of this library:

    So, in most cases all your request calls with simplified api of this library (like bot.getMe()) will looks like bot.execute(GetMe). Result of these calls is defined in type of any request (for example, for GetMe request the result type is ExtendedBot). As a result, you can avoid any extension api (like special API extensions) and use low level request with full controlling of the whole logic flow.

    "},{"location":"tgbotapi/logic/low-level-work-with-bots.html#how-to-handle-updates","title":"How to handle updates","text":"

    As was written above, it will require some request:

    val updates = bot.execute(GetUpdates())\n

    Result type of GetUpdates request is Update. You may find inheritors of this interface in Update kdocs.

    As you know, Telegram have the feature named Media Groups. Media groups have several differences with the common messages:

    "},{"location":"tgbotapi/logic/media-groups.html#specific-of-media-groups-in-libraries","title":"Specific of media groups in libraries","text":"

    Row updates

    In tgbotapi there is no any additional handling of media groups by default and in case you will use simple bot.getUpdates, you will get the list of row updates and media groups will be included in this list as separated messages with MediaGroupPartContent. In that case you may use convertWithMediaGroupUpdates to be able to work with media groups as will be described below

    In case you are using standard long polling (one of alternatives is telegramBotWithBehaviourAndLongPolling) or webhooks updates will be converted uner the hood and as a result, you will take media groups as a content in one message:

    telegramBotWithBehaviourAndLongPolling(\n\"token\"\n) {\nonVisualGallery { // it: CommonMessage<MediaGroupContent<VisualMediaGroupPartContent>>\nit.content // MediaGroupContent<VisualMediaGroupPartContent>\nit.content.group // List<MediaGroupCollectionContent.PartWrapper<VisualMediaGroupPartContent>>\nit.content.group.forEach { // it: MediaGroupCollectionContent.PartWrapper<VisualMediaGroupPartContent>\nit.messageId // source message id for current media group part\nit.sourceMessage // source message for current media group part\nit.content // VisualMediaGroupPartContent\nprintln(it.content) // will print current content part info\n}\n}\n}\n

    KDocs:

    In two words, in difference with row Telegram Bot API, you will take media groups in one message instead of messages list.

    "},{"location":"tgbotapi/logic/types-conversations.html","title":"Types conversations","text":"

    One of the most important topics in context of tgbotapi is types conversations. This library is very strong-typed and a lot of things are based on types hierarchy. Lets look into the hierarchy of classes for the Message in 0.35.8:

    As you may see, it is a little bit complex and require several tools for types conversation.

    "},{"location":"tgbotapi/logic/types-conversations.html#as","title":"As","text":"

    as conversations will return new type in case if it is possible. For example, when you got Message, you may use asContentMessage conversation to get message with content:

    val message: Message;\nprintln(message.asContentMessage() ?.content)\n

    This code will print null in case when message is not ContentMessage, and content when is.

    "},{"location":"tgbotapi/logic/types-conversations.html#require","title":"Require","text":"

    require works like as, but instead of returning nullable type, it will always return object with required type OR throw ClassCastException:

    val message: Message;\nprintln(message.requireContentMessage().content)\n

    This code will throw exception when message is not ContentMessage and print content when is.

    "},{"location":"tgbotapi/logic/types-conversations.html#when","title":"When","text":"

    when extensions will call passed block when type is correct. For example:

    // Step 1 - create filter\nval filter = flowsUpdatesFilter {\n// Step 2 - set up handling. In this case we will print any message from group or user in console\nmessageFlow.onEach {\nprintln(it)\n}.launchIn(someCoroutineScope)\n}\n// Step 3 - passing updates to filter\nbot.getUpdates().forEach {\nfilter.asUpdatesReceiver(it)\n}\n

    longPolling is a simple way to start getting updates and work with bot:

    Due to the fact, that anyway you will get updates in one format (Update objects), some time ago was solved to create one point of updates filters for more usefull way of updates handling

    "},{"location":"tgbotapi/updates/updates-filters.html#updatesfilter","title":"UpdatesFilter","text":"

    UpdatesFilter currently have two properties:

    Anyway, this filter can\u2019t work with updates by itself. For retrieving updates you should pass this filter to some of getting updates functions (long polling or webhooks).

    "},{"location":"tgbotapi/updates/updates-filters.html#simpleupdatesfilter","title":"SimpleUpdatesFilter","text":"

    SimpleUpdatesFilter is a simple variant of filters. It have a lot of UpdateReceiver properties which can be set up on creating of this object. For example, if you wish to get messages from chats (but not from channels), you can use next snippet:

    SimpleUpdatesFilter {\nprintln(it)\n}\n
    "},{"location":"tgbotapi/updates/updates-filters.html#flowsupdatesfilter","title":"FlowsUpdatesFilter","text":"

    A little bit more modern way is to use FlowsUpdatesFilter. It is very powerfull API of Kotlin Coroutines Flows, built-in support of additional extensions for FlowsUpdatesFilter and Flow<...> receivers and opportunity to split one filter for as much receivers as you want. Filter creating example:

    val scope = CoroutineScope(Dispatchers.Default)\nflowsUpdatesFilter {\nmessageFlow.onEach {\nprintln(it)\n}.launchIn(scope)\n}\n
    "},{"location":"tgbotapi/updates/updates-filters.html#combining-of-flows","title":"Combining of flows","text":"

    In cases you need not separate logic for handling of messages from channels and chats there are three ways to combine different flows into one:

    FlowsUpdatesFilter have a lot of extensions for messages types filtering:

    flowsUpdatesFilter {\ntextMessages(scope).onEach {\nprintln(it) // will be printed each message from channels and chats both with content only `TextContent`\n}.launchIn(scope)\n}\n

    The same things were created for media groups:

    flowsUpdatesFilter {\nmediaGroupMessages(scope).onEach {\nprintln(it) // will be printed each media group messages list from both channels and chats without filtering of content\n}.launchIn(scope)\nmediaGroupPhotosMessages(scope).onEach {\nprintln(it) // will be printed each media group messages list from both channels and chats with PhotoContent only\n}.launchIn(scope)\nmediaGroupVideosMessages(scope).onEach {\nprintln(it) // will be printed each media group messages list from both channels and chats with VideoContent only\n}.launchIn(scope)\n}\n

    Besides, there is an opportunity to avoid separation on media groups and common messages and receive photos and videos content in one flow:

    flowsUpdatesFilter {\nsentMessagesWithMediaGroups(scope).onEach {\nprintln(it) // will be printed each message including each separated media group message from both channels and chats without filtering of content\n}.launchIn(scope)\nphotoMessagesWithMediaGroups(scope).onEach {\nprintln(it) // will be printed each message including each separated media group message from both channels and chats with PhotoContent only\n}.launchIn(scope)\nvideoMessagesWithMediaGroups(scope).onEach {\nprintln(it) // will be printed each message including each separated media group message from both channels and chats with VideoContent only\n}.launchIn(scope)\n}\n

    In telegram bot API there is an opportunity to get updates via webhooks. In this case you will be able to retrieve updates without making additional requests. Most of currently available methods for webhooks are working on ktor server for JVM. Currently, next ways are available for using for webhooks:

    "},{"location":"tgbotapi/updates/webhooks.html#setwebhookinfoandstartlistenwebhooks","title":"setWebhookInfoAndStartListenWebhooks","text":"

    It is the most common way to set updates webhooks and start listening of them. Example:

    val bot = telegramBot(TOKEN)\nval filter = flowsUpdatesFilter {\n// ...\n}\nbot.setWebhookInfoAndStartListenWebhooks(\n8080, // listening port. It is required for cases when your server hidden by some proxy or other system like Heroku\nCIO, // default ktor server engine. It is recommended to replace it with something like `Netty`. More info about engines here: https://ktor.io/servers/configuration.html\nSetWebhook(\n\"address.com/webhook_route\",\nFile(\"/path/to/certificate\").toInputFile(), // certificate file. More info here: https://core.telegram.org/bots/webhooks#a-certificate-where-do-i-get-one-and-how\n40, // max allowed updates, by default is null\nfilter.allowedUpdates\n),\n{\nit.printStackTrace() // optional handling of exceptions\n},\n\"0.0.0.0\", // listening host which will be used to bind by server\n\"subroute\", // Optional subroute, if null - will listen root of address\nWebhookPrivateKeyConfig( // optional config of private key. It will be installed in server to use TLS with custom certificate.

    If you will use previous example, ktor server will bind and listen url 0.0.0.0:8080/subroute and telegram will send requests to address address.com/webhook_route with custom certificate. Alternative variant will use the other SetWebhook request variant:

    SetWebhook(\n\"address.com/webhook_route\",\n\"some_file_bot_id\".toInputFile(),\n40, // max allowed updates, by default is null\nfilter.allowedUpdates\n)\n

    As a result, request SetWebhook will be executed and after this server will start its working and handling of updates.

    "},{"location":"tgbotapi/updates/webhooks.html#startlistenwebhooks","title":"startListenWebhooks","text":"

    This function is working almost exactly like previous example, but this one will not set up webhook info in telegram:

    val filter = flowsUpdatesFilter {\n// ...\n}\nstartListenWebhooks(\n8080, // listening port. It is required for cases when your server hidden by some proxy or other system like Heroku\nCIO, // default ktor server engine. It is recommended to replace it with something like `Netty`.

    The result will be the same as in previous example: server will start its working and handling of updates on 0.0.0.0:8080/subroute. The difference here is that in case if this bot must not answer or send some requiests - it will not be necessary to create bot for receiving of updates.

    KSLog is a simple multiplatform tool for native logging.

    "},{"location":"kslog/logging.html","title":"Logging","text":"

    Message type notice

    On this page all the messages will be just simple String, but you may pass any object as the message

    As has been said in the setup section, this library contains next levels of logging with their default representations on each platform:

    Weight (by order) LogLevel name JS JVM Loggers Android 0 DEBUG console.log Level.FINEST Log.d 1 VERBOSE console.info Level.FINE Log.v 2 INFO console.info Level.INFO Log.i 3 WARNING console.warn Level.WARNING Log.w 4 ERROR console.error Level.SEVERE Log.e 5 ASSERT console.error Level.SEVERE Log.wtf

    Each of these levels have fullname and shortname shortcat extensions:

    And any of these shortcuts may accept one of several arguments combinations:

    So, when you want to log some expected exception, there are three common ways to do it:

    val logger = KSLog.default\n// with callback\nlogger.info(tag, throwable) {\n\"Some your message for this event\"\n}\n// with suspendable callback\nlogger.infoS(tag, throwable) {\nwithContext(Dispatchers.Default) {\n\"Some your message for this event\"\n}\n}\n// Just with message\nlogger.info(\"Some your message for this event\", throwable)\n// With message and tag as strings\nlogger.info(tag, \"Some your message for this event\", throwable)\n

    Of course, any of this calls can be shortenned:

    val logger = KSLog.default\n// with callback\nlogger.i(tag, throwable) {\n\"Some your message for this event\"\n}\n// with suspendable callback\nlogger.iS(tag, throwable) {\nwithContext(Dispatchers.Default) {\n\"Some your message for this event\"\n}\n}\n// Just with message\nlogger.i(\"Some your message for this event\", throwable)\n// With message and tag as strings\nlogger.i(tag, \"Some your message for this event\", throwable)\n

    There is special shortcat - for base performLog. In that case the only change is that you will require to pass the LogLevel more obviously:

    val logger = KSLog.default\n// with callback\nlogger.log(LogLevel.INFO, tag, throwable) {\n\"Some your message for this event\"\n}\n// with suspendable callback\nlogger.logS(LogLevel.INFO, tag, throwable) {\nwithContext(Dispatchers.Default) {\n\"Some your message for this event\"\n}\n}\n// Just with message\nlogger.log(LogLevel.INFO, \"Some your message for this event\", throwable)\n// With message and tag as strings\nlogger.log(LogLevel.INFO, tag, \"Some your message for this event\", throwable)\n

    OR

    val logger = KSLog.default\n// with callback\nlogger.l(LogLevel.INFO, tag, throwable) {\n\"Some your message for this event\"\n}\n// with suspendable callback\nlogger.lS(LogLevel.INFO, tag, throwable) {\nwithContext(Dispatchers.Default) {\n\"Some your message for this event\"\n}\n}\n// Just with message\nlogger.l(LogLevel.INFO, \"Some your message for this event\", throwable)\n// With message and tag as strings\nlogger.l(LogLevel.INFO, tag, \"Some your message for this event\", throwable)\n

    The main point in setup in your code is to setup default logger:

    KSLog(\n\"loggingWithCustomFormat\",\nmessageFormatter = { level, tag, message, throwable ->\nprintln(\"[$level] $tag - $message: $throwable\")\n}\n)\n

    Additionally you may use one of several different settings:

    In case you are passing minLoggingLevel, the level and more important levels will be passed to logs. For example, when you are settings up your logger as in next snippet:

    "},{"location":"kslog/setup.html#taglogger","title":"TagLogger","text":"

    It is simple value class which can be used for zero-cost usage of some tag and calling for KSLog.default. For example, if you will create tag logger with next code:

    In the example above baseLogger will perform logs in two ways: when it has been called directly or when we call log performing with the tag \"base\" or null. Besides, you can see there extension filtered which allow to create FilterKSLog logger with simple lambda.

    This logger accepts map of types with the target loggers. You may build this logger with the special simple DSL:

    class SomeClass {\ninit {\nlogger.i(\"inited\")\n}\n}\n

    The code above will trigger calling of logging in KSLog.default with level LogLevel.INFO using tag SomeClass and message \"inited\". As you could have guessed, logger is using TagLogger with logTag underhood and the most expensive operation here is automatical calculation of logTag.

    But there is a little bit more useful way: entities builder:

    First of all, you will need to use one more library:

    build.gradle:

    implementation \"io.ktor:ktor-client-okhttp:2.0.1\"\n

    Dependency note

    In the snippet above was used version 2.0.1 which is actual for TelegramBotAPI at the moment of filling this documentation (May 22 2022, TelegramBotAPI version 2.0.0) and you can update version of this dependency in case if it is outdated.

    For configuring proxy for your bot inside your program, you can use next snippet:

    val botToken = \"HERE MUST BE YOUR TOKEN\"\nval bot = telegramBot(botToken) {\nktorClientEngineFactory = OkHttp\nproxy = ProxyBuilder.socks(\"127.0.0.1\", 1080)\n}\n

    Explanation line by line:

    1. val botToken = \"HERE MUST BE YOUR TOKEN\" - here we are just creating variable botToken
    2. val bot = telegramBot(botToken) { - start creating bot
    3. ktorClientEngineFactory = OkHttp - setting up engine factory of our bot. On the time of documentation filling, OkHttp is one of the engines in Ktor system which supports socks proxy. More you can read on Ktor site in subparts about engines and proxy
    4. proxy = ProxyBuilder.socks(\"127.0.0.1\", 1080) - here we are setting up our proxy. Here was used local server which (as assumed) will connect to server like shadowsocks

    flowsUpdatesFilter {\ntextMessages(scope).onEach {\nprintln(it) // will be printed each message from channels and chats both with content only `TextContent`\n}.launchIn(scope)\n}\n

    The same things were created for media groups:

    flowsUpdatesFilter {\nmediaGroupMessages(scope).onEach {\nprintln(it) // will be printed each media group messages list from both channels and chats without filtering of content\n}.launchIn(scope)\nmediaGroupPhotosMessages(scope).onEach {\nprintln(it) // will be printed each media group messages list from both channels and chats with PhotoContent only\n}.launchIn(scope)\nmediaGroupVideosMessages(scope).onEach {\nprintln(it) // will be printed each media group messages list from both channels and chats with VideoContent only\n}.launchIn(scope)\n}\n

    Besides, there is an opportunity to avoid separation on media groups and common messages and receive photos and videos content in one flow:

    flowsUpdatesFilter {\nsentMessagesWithMediaGroups(scope).onEach {\nprintln(it) // will be printed each message including each separated media group message from both channels and chats without filtering of content\n}.launchIn(scope)\nphotoMessagesWithMediaGroups(scope).onEach {\nprintln(it) // will be printed each message including each separated media group message from both channels and chats with PhotoContent only\n}.launchIn(scope)\nvideoMessagesWithMediaGroups(scope).onEach {\nprintln(it) // will be printed each message including each separated media group message from both channels and chats with VideoContent only\n}.launchIn(scope)\n}\n

    In telegram bot API there is an opportunity to get updates via webhooks. In this case you will be able to retrieve updates without making additional requests. Most of currently available methods for webhooks are working on ktor server for JVM. Currently, next ways are available for using for webhooks:

    "},{"location":"tgbotapi/updates/webhooks.html#setwebhookinfoandstartlistenwebhooks","title":"setWebhookInfoAndStartListenWebhooks","text":"

    It is the most common way to set updates webhooks and start listening of them. Example:

    val bot = telegramBot(TOKEN)\nval filter = flowsUpdatesFilter {\n// ...\n}\nbot.setWebhookInfoAndStartListenWebhooks(\n8080, // listening port. It is required for cases when your server hidden by some proxy or other system like Heroku\nCIO, // default ktor server engine. It is recommended to replace it with something like `Netty`. More info about engines here: https://ktor.io/servers/configuration.html\nSetWebhook(\n\"address.com/webhook_route\",\nFile(\"/path/to/certificate\").toInputFile(), // certificate file. More info here: https://core.telegram.org/bots/webhooks#a-certificate-where-do-i-get-one-and-how\n40, // max allowed updates, by default is null\nfilter.allowedUpdates\n),\n{\nit.printStackTrace() // optional handling of exceptions\n},\n\"0.0.0.0\", // listening host which will be used to bind by server\n\"subroute\", // Optional subroute, if null - will listen root of address\nWebhookPrivateKeyConfig( // optional config of private key. It will be installed in server to use TLS with custom certificate. More info here: https://core.telegram.org/bots/webhooks#a-certificate-where-do-i-get-one-and-how\n\"/path/to/keystore.jks\",\n\"KeystorePassword\",\n\"Keystore key alias name\",\n\"KeystoreAliasPassword\"\n),\nscope, // Kotlin coroutine scope for internal transforming of media groups\nfilter.asUpdateReceiver\n)\n

    If you will use previous example, ktor server will bind and listen url 0.0.0.0:8080/subroute and telegram will send requests to address address.com/webhook_route with custom certificate. Alternative variant will use the other SetWebhook request variant:

    SetWebhook(\n\"address.com/webhook_route\",\n\"some_file_bot_id\".toInputFile(),\n40, // max allowed updates, by default is null\nfilter.allowedUpdates\n)\n

    As a result, request SetWebhook will be executed and after this server will start its working and handling of updates.

    "},{"location":"tgbotapi/updates/webhooks.html#startlistenwebhooks","title":"startListenWebhooks","text":"

    This function is working almost exactly like previous example, but this one will not set up webhook info in telegram:

    val filter = flowsUpdatesFilter {\n// ...\n}\nstartListenWebhooks(\n8080, // listening port. It is required for cases when your server hidden by some proxy or other system like Heroku\nCIO, // default ktor server engine. It is recommended to replace it with something like `Netty`. More info about engines here: https://ktor.io/servers/configuration.html\n{\nit.printStackTrace() // optional handling of exceptions\n},\n\"0.0.0.0\", // listening host which will be used to bind by server\n\"subroute\", // Optional subroute, if null - will listen root of address\nWebhookPrivateKeyConfig( // optional config of private key. It will be installed in server to use TLS with custom certificate. More info here: https://core.telegram.org/bots/webhooks#a-certificate-where-do-i-get-one-and-how\n\"/path/to/keystore.jks\",\n\"KeystorePassword\",\n\"Keystore key alias name\",\n\"KeystoreAliasPassword\"\n),\nscope, // Kotlin coroutine scope for internal transforming of media groups\nfilter.asUpdateReceiver\n)\n

    The result will be the same as in previous example: server will start its working and handling of updates on 0.0.0.0:8080/subroute. The difference here is that in case if this bot must not answer or send some requiests - it will not be necessary to create bot for receiving of updates.

    "},{"location":"tgbotapi/updates/webhooks.html#extensions-includewebhookhandlinginroute-and-includewebhookhandlinginroutewithflows","title":"Extensions includeWebhookHandlingInRoute and includeWebhookHandlingInRouteWithFlows","text":"

    For these extensions you will need to start your server manualy. In common case it will look like:

    val scope = CoroutineScope(Dispatchers.Default)\nval filter = flowsUpdatesFilter {\n// ...\n}\nval environment = applicationEngineEnvironment {\nmodule {\nrouting {\nincludeWebhookHandlingInRoute(\nscope,\n{\nit.printStackTrace()\n},\nfilter.asUpdateReceiver\n)\n}\n}\nconnector {\nhost = \"0.0.0.0\"\nport = 8080\n}\n}\nembeddedServer(CIO, environment).start(true) // will start server and wait its stoping\n

    In the example above server will started and binded for listening on 0.0.0.0:8080.
