In short

Open your group, go to the Triggers tab, click Add trigger, choose a match mode (contains, exact, regex, commands or mentions), enter the pattern, pick an action such as Reply, write the response text, set priority and save.

Create a trigger on the Triggers page.

1What a trigger is

A trigger is an automatic reaction to a condition. When a message matches the pattern you set, the bot fires the action you chose, from posting a ready-made reply to muting or banning the sender.

Triggers are great for FAQ auto-answers, rule reminders and lightweight automation, as well as for moderating specific phrases, so your group feels responsive even when no admin is online.

  • Fires the moment a matching message appears.
  • Can reply, delete, warn, mute, kick or ban.
  • Each trigger can be switched on or off, edited, and exported or imported as a file.

2Match modes

The match mode decides how the bot compares a message to your pattern. Pick the one that fits your goal.

  • Contains: fires if the message contains your text anywhere. The most common choice.
  • Exact: fires only when the whole message equals your text.
  • Regex: matches by a regular expression pattern for advanced cases, such as ^hello.*world$.
  • Commands: reacts to slash commands only, like /rules.
  • Mentions: reacts to @mentions only.
  • All: reacts to every message, so combine it with the extra conditions below.

3Action and response text

Choose what the trigger does: Reply, Delete, Warn, Mute, Kick or Ban. For Reply, write the message the bot posts back. You can also turn on Delete original to remove the message that triggered the reaction.

The response text supports placeholders shown under the field, so you can greet a user by name or reference the group. That small touch makes auto-answers feel personal instead of robotic.

For an FAQ auto-answer, use the Contains mode with the Reply action and leave Delete original off, so the question stays visible next to your answer.

4Extra conditions and priority

Under Additional conditions you can narrow when a trigger fires: only for new users, only for forwarded messages, or only for replies. Combine these with a match mode to target exactly the situation you want.

Priority (1 to 100) sets the order when several triggers could match. Higher priority runs first. For moderation triggers this works just like custom rules, see the custom rule tutorial.
