JSON payload
Full submission data plus form metadata in a clean JSON shape.
Developer tools
Send submission payloads to Zapier, Make, n8n, Slack, or any custom endpoint.
Webhooks are the universal escape hatch. Point Core Forms at any HTTP endpoint and it’ll POST a JSON payload of every submission — perfect for Zapier zaps, Make scenarios, n8n flows, or your own API.
Full submission data plus form metadata in a clean JSON shape.
Add Authorization, X-API-Key, or any signature header.
Built-in retry policy with exponential backoff.
Only POST when the submission matches your conditions.
Zapier, Make, n8n, your own API — anything that speaks HTTP.
Form → Actions → Webhook, paste the URL and pick the method (POST / PUT / PATCH).
Authorization, X-API-Key, signing secrets.
