Formstack

Connect Formstack to send form submissions to Finseo for attribution tracking. Formstack’s native webhooks POST JSON payloads with the form field data on every submission.

​
Get your webhook URL

  1. In Finseo, open Integrations → Formstack → Connect.
  2. Copy your personal webhook URL (contains your project ID, ?source=formstack, and a secret token):

​
Set up the Formstack webhook

  1. In Formstack, open your form and go to Settings → Integrations → Webhooks.
  2. Add your Finseo webhook URL as the endpoint.
  3. Choose to send the data as JSON with field labels if available, then save.
See Formstack’s webhook help article for details.

​
Test and map fields

  • Use the live listener in the Finseo connect dialog: submit a test entry and inspect the received payload.
  • Formstack maps field IDs to values — select your “How did you find us?” field under Field Mapping in the dialog.

​
Troubleshooting

Confirm the webhook is active on the specific form (webhooks are configured per form, not account-wide) and the URL includes source and token parameters.
Use Field Mapping once to select the right field — Finseo remembers the mapping for all future submissions.
