Integrate document signing into your applications with our RESTful API. Create, manage, and track documents and signing requests programmatically.
Generate one in your settings. It starts with sq_ and is shown to you only once.
Send the PDF to the documents endpoint and keep the id it returns.
Create a signing request with that id and your signers. SignQuick emails each of them their link.
Send your API key as a Bearer token on every request. Keys are created in your settings and can be revoked at any time.
Authorization: Bearer sq_your_api_key_here
Pass the key in the Authorization header over HTTPS. It belongs on your server, never in code a browser can read.
Requests are metered per key. A 429 response means you have gone too fast, wait and retry.
A key resolves to the account that created it and reaches nothing outside it. Revoke it from your settings at any time.
Everything you can do from your own code.
