Zefi APIBuild on Zefi from your own systems

A REST API over the things Zefi already does — starting with survey links, so a CRM, a support desk or a batch job can mint one without opening the platform.

Quickstart

API reference

One key, one workspace

Keys are scoped to a single workspace, with read and write granted separately. Created, replaced and revoked from Settings → API Keys.

Predictable errors

RFC 9457 problem documents with a stable code to branch on, published rate limits, and headers telling you what is left before you have to ask.

Partial success is an answer

Batch endpoints report per entry. One bad row out of fifty does not cost you the other forty-nine.

What you can build today

Survey links. Create the links Zefi would otherwise generate from the platform UI, carrying your own customer and respondent metadata, so a response arrives already attributed instead of anonymous.

Quickstart — a link in about five minutes
How links behave — single-use, expiry, and what a recipient cannot change
Creating links in bulk — up to 50 per call

Everything else

These apply to every part of the API, not just survey links:

Authentication — creating a key, scopes, replacing and revoking
Errors — the shape of a failure and which codes are worth retrying
Rate limits — what the budgets are and how to stay inside them

The API is versioned in the path. v1 is current, and additive changes — new fields, new endpoints — will not break a working integration.
