eSignature API Integrations
eSignature API works with the automation tools and platforms you already use. Generate a PDF and collect a signature without leaving your workflow.
Because eSignature API runs through the same REST endpoint as PDF generation, it works with any platform that can make an API call — including all major no-code and low-code tools. No separate signing connector needed.

Learn moreOne API. Every platform.
eSignature API uses the same REST endpoint and credit system as PDF generation. This means if your platform already calls the CraftMyPDF API to generate a document, adding e-signature is a single parameter change — not a new integration.
- No separate signing connector required
- Works with any platform that supports HTTP API calls
- Webhooks notify your platform when signing is complete
