Scope: imbot

Who can execute the method: owner of the registered bot

The method imbot.v2.Bot.update updates the properties of the bot.

BotToken Rotation

Passing fields.botToken replaces the current bot token with a new one. Request authorization is performed with the old token at the top level; the new token is passed in fields.botToken.

After a successful rotation:

  • All the bot's subscriptions to events ONIMBOTV2* are re-linked to the new APPLICATION_TOKEN if the bot operates in webhook mode.
  • The old token instantly loses access to the bot — subsequent requests with it will return the error BOT_OWNERSHIP_ERROR.

In case of a collision (the new token is already linked to another bot), a generic error BOT_TOKEN_ROTATION_FAILED is returned without specifying the reason, to avoid revealing the existence of foreign tokens.

Managing Event Subscriptions

When calling Bot.update, the bot's subscriptions to events ONIMBOTV2* are automatically brought up to date:

Change

Behavior

webhookUrl changes (mode remains webhook)

The old eight subscriptions to the previous URL are deleted, and eight new ones are created for the new URL. The previous URL stops receiving events

eventMode: webhookfetch

All eight subscriptions of the bot are deleted. After the transition, events are only available through imbot.v2.Event.get

eventMode: fetchwebhook

Eight subscriptions are created for the specified webhookUrl. If there were any "legacy" subscriptions on another URL, they are also deleted before creating new ones

Other fields properties, isHidden, and others

Subscriptions remain unchanged

OAuth applications with multiple bots: if one application has registered multiple bots under a common clientId, the automatic cleanup of subscriptions when changing webhookUrl or eventMode is skipped to avoid affecting subscriptions of neighboring bots. Webhook-authorized bots with their own botToken do not have this limitation — each of them has its own synthetic APPLICATION_TOKEN.
