Cintra People - Integrations API 1.0 (1.0.43)
Download OpenAPI specification:Download
The Cintra IAPI is a RESTful HTTP API built on the JSON:API specification. It exposes predictable resource URLs, uses standard HTTP response codes for error signalling, and exchanges JSON in request and response bodies. Any HTTP/REST library in your language of choice is compatible with this API.
Send dates as YYYY-MM-DD, for example 2026-11-01. Dates come back as a date-time at midnight
with no offset, for example 2026-11-01T00:00:00, even where a property is documented as format: date.
Read only the date part.
List endpoints that support paging take page[number] (from 1) and page[size], the number of records
per page, from 1 to 100. page[size] defaults to 100. Responses carry no next or last links and no
totals, so keep requesting the next page until one comes back with fewer records than the size you asked for.
