Any form or app (webhooks)
Paste an API keyEvery flow has a secret URL — anything that can POST can start it.
What you can do
- Webhook trigger — each flow gets a unique, rotatable URL; the JSON payload is available in every step as {{trigger.body.field}}
- HTTP step — call any REST API outbound as part of a flow
Point any app at your flow
- 1Open your flow, set the trigger to “When a webhook arrives”, and copy the URL shown.
- 2Paste that URL into the sending app's webhook settings (Typeform, Stripe, Shopify, Tally, your own backend — anything).
- 3Send a test event, then reference values as {{trigger.body.field}} in any step.
Use it in a flow
In the flow builder, add the Any form or app (webhooks) step, pick your connection, and fill the fields — values from earlier steps drop in as {{s1.field}} placeholders. Then hit Test this step in the step's panel to run it on its own before switching the flow on.
Troubleshooting
404 when posting

The flow is turned Off — flip it On before sending events.
FAQ
Is the URL guessable?
No — it contains a secret token, compared in constant time. Rotate it any time from the trigger bar.
