Frequently asked questions

Have a question? Here are answers to the most common ones.

From your SIGNESTO workspace, open “API and webhooks” under integrations and create a key. It is shown only once, so store it somewhere safe. You can revoke it at any time.

Yes. Test keys are included in the subscription (48-hour trial included): they are read-only and let you validate your integration without affecting your collaborators. Their calls count towards the monthly quota.

The REST API uses JSON and standard Bearer authentication: any tool able to send an HTTP request can connect to it, including Zapier or Make.

You provide a receiving URL: SIGNESTO sends a signed request to it for each event (signature created, updated or deployed), so your tools stay in sync.

The API is included in the SIGNESTO subscription: 1,000 requests per month per workspace, and 10 requests per second per key. If you exceed them, the API responds with a 429 code.

The official SDKs (PHP, Node.js, Python) are in preparation. In the meantime, the API documentation provides ready-to-copy cURL, Python, JavaScript and PHP examples.
