SignatureAPI for Zapier

We ran a private preview of a dedicated Zapier connector. We are not continuing it for now.

You do not need one. Zapier calls any REST API through its Webhooks by Zapier action, and that is how most of our no-code customers connect: the platform’s own API connector, pointed at the SignatureAPI REST API. The same approach works in Make, n8n, Workato, and any other tool with an HTTP step.

Send documents for signature

Add a Webhooks by Zapier action, choose POST, and call https://api.signatureapi.com/v1/envelopes. Pass your API key in the X-API-Key header. The Quickstart shows the request body.

React to signing events

Add a Catch Hook trigger, copy the URL Zapier gives you, and register it as a webhook endpoint in your Dashboard. Zapier receives an event every time an envelope or recipient changes state.

API Quickstart

Create your first envelope and send it for signature.

Webhooks

Every event we emit, and what each one carries.

Contact us if you would rather have a dedicated connector. Enough demand and we will revisit it.
