Activity Messenger does not have a native Zapier app, but a form can trigger a Zap through its outgoing webhook. Activity Messenger sends the completed form submission to a Webhooks by Zapier Catch Hook URL.
You need:
Treat the Zapier Catch Hook URL as a secret. Anyone with the URL can send data to the Zap.
Use Catch Hook, not Retrieve Poll. Activity Messenger sends an HTTP POST with a JSON request body.
The setting belongs to this form. Repeat these steps for every form that should trigger a Zap.
The payload includes:
idemailmobilefirst_namelast_namecreated_atform_answersform_answers contains the answers collected by the form. Submit a realistic
test response so Zapier can discover the answer fields you plan to use.
To add every registration to a spreadsheet, create a Catch Hook trigger, paste
its URL into the registration form, and submit a test registration. In the next
Zap step, map first_name, last_name, email, and the required
form_answers values to spreadsheet columns.
