> Receive Formstack form submissions in Finseo for attribution tracking.

# 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):

```text theme={"system"}
https://app.finseo.ai/api/attribution/webhook/YOUR_PROJECT_ID?source=formstack&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](https://help.formstack.com/s/article/Webhook-integration) 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

  <Accordion title="Submissions don't arrive">
    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.
  </Accordion>

  <Accordion title="The attribution answer isn't detected">
    Use Field Mapping once to select the right field — Finseo remembers the mapping for all future submissions.
