The Certyneo electronic signature API on RapidAPI
Subscribe to the Certyneo API directly from the RapidAPI marketplace: a single RapidAPI key to test and integrate envelope creation, sending for signature and status tracking, without creating a separate Certyneo account just to explore the API.
Discovery via RapidAPI. A Certyneo account is still required for production use beyond the discovery quota.
Why discover Certyneo via RapidAPI
RapidAPI is handy for quickly evaluating an API without multiplying sign-ups — your single RapidAPI key covers the whole catalogue you follow on the marketplace.
One RapidAPI key to test everything
If you already use other APIs listed on RapidAPI, your existing key also works with Certyneo — no new sign-up needed.
Test before integrating
RapidAPI's "Test Endpoint" tab lets you send a request straight from the browser, no code required, to explore the API's responses.
Transparent pricing
The usage tiers shown on the RapidAPI listing mirror the Certyneo plans, with a free quota to discover the API.
Built-in documentation
Every endpoint is documented with its parameters, response codes and a sample request, right inside the RapidAPI interface.
What the RapidAPI listing covers
An overview of the endpoint groups exposed on the RapidAPI marketplace.
| Group | What it contains |
|---|---|
| Envelopes | Create, send, list and check the status of a signature envelope. |
| Documents | Upload a document or import it from a URL to include it in an envelope. |
| Signers | Add recipients and set their signature level (SES/AES). |
| Status and proof | Retrieve an envelope's status and download the eIDAS proof certificate once signed. |
The RapidAPI listing exposes a stable subset of the REST v1 API. The full set of endpoints stays available with a regular Certyneo API key.

- All requests travel over HTTPS/TLS 1.2 minimum.
- Access via RapidAPI is limited to the quota and endpoints published on the listing.
- No signer data is stored by RapidAPI: the platform only relays the request to the Certyneo API.
- The RapidAPI key can be revoked from your RapidAPI dashboard, independently of your Certyneo API keys.
