Use the REST API to retrieve, create, update and delete Celoxis data and perform supported entity actions.

All endpoints are relative to your Celoxis installation:

Example
https://<your-celoxis-host>/psa/api/v2

The examples use https://app.celoxis.com/psa/api/v2.

Supported entities

An entity is a type of Celoxis record, such as a project. Entities also have associations with other entities. For example, a task is associated with its project and with another task that is its parent.

Use the entity key in API URLs. In the paths below, replace {entity} with a key from this table.
