Trigger types

TriggerStarts the automation when
Comment keywordSomeone comments on a post or reel of a connected account. See comment to DM automations.
DM keywordSomeone sends a direct message to a connected account.
Story replySomeone replies to one of your stories. See story reply automations.

Set the trigger when you create the automation, or change it later on the trigger step in the flow builder.

Set keywords

Select the trigger step and enter the keywords in the Keywords field, separated by commas, for example link, free, price. Any one of them starts the automation.

  • Whole words only

    link matches "Link please!" but not "linkedin". A keyword can also be a phrase of several words.

  • Capital letters do not matter

    GUIDE, Guide and guide are the same keyword.

  • No keywords means everything

    An empty field answers every comment, or every DM or story reply. For DMs and story replies such an automation answers the same person at most once every 24 hours.

Which automation answers

Each comment, DM or story reply starts at most one automation. When several live automations match, ChatPeak picks in this order:

  1. 1
    The more specific group

    For a comment, automations limited to that post come before automations for all posts. For a story reply, story reply automations come before DM keyword automations.

  2. 2
    Keyword matches first

    Within a group, an automation whose keyword matched comes before one without keywords.

  3. 3
    Newest published first

    Among equal matches, the most recently published automation answers.

Choosing a good keyword

  • Short and distinctive

    One word that rarely appears by accident, such as guide rather than yes.

  • Tied to the reward

    A keyword that names what people get is easier to remember and to type.
