set-webhook

setWebhook

Use this method to specify a URL and receive incoming updates via an outgoing webhook
Whenever there is an update for the bot, we will send an HTTPS POST request to the specified URL, containing a JSON-serialized Update
In case of an unsuccessful request (a request with response HTTP status code different from 2XY), we will repeat the request and give up after a reasonable amount of attempts
If you'd like to make sure that the webhook was set by you, you can specify secret data in the parameter secret_token
If specified, the request will contain a header “X-Telegram-Bot-Api-Secret-Token” with the secret token as content.

Parameters for set-webhook
Field	Description
`url` *	HTTPS URL to send updates to Use an empty string to remove webhook integration

`ip_address`	The fixed IP address which will be used to send webhook requests instead of the IP address resolved through DNS
`max_connections`	The maximum allowed number of simultaneous HTTPS connections to the webhook for update delivery, 1-100 Defaults to 40 Use lower values to limit the load on your bot's server, and higher values to increase your bot's throughput.
`allowed_updates`	A JSON-serialized list of the update types you want your bot to receive For example, specify ["message", "edited_channel_post", "callback_query"] to only receive updates of these types See Update for a complete list of available update types Specify an empty list to receive all update types except chat_member, message_reaction, and message_reaction_count (default) If not specified, the previous setting will be used . Please note that this parameter doesn't affect updates created before the call to the setWebhook, so unwanted updates may be received for a short period of time.
`drop_pending_updates`	Pass True to drop all pending updates
`secret_token`	A secret token to be sent in a header “X-Telegram-Bot-Api-Secret-Token” in every webhook request, 1-256 characters Only characters A-Z, a-z, 0-9, _ and - are allowed The header is useful to ensure that the request comes from a webhook set by you.
