Webhook test
  • Before moving on, go to your Webhook settings page in the Architect platform and submit a test form. This sends a sample to the webhook.
If you are using multi-field forms, you can test directly from the Architect page by submitting the full form. This will help you with mapping all of the fields to the right areas later.

  • Click Continue.

Test and publish your Zap
