Retrieving items belonging to a specific baseline using Rest API

IV_10178511 — Thu, 26 Feb 2026 15:09:22 GMT

Dear Support!

We are using Codebeamer 2.0.0.0

We would like to retrieve all the items of a specific tracker that are associated with a specific baseline using Rest API.

Is this possible?

Can you provide a "URL-template" for this?

Thank you in advance!

An additional question: in case this would not be possible with our current version, can this be done with a higher version of Codebeamer?

Hello @IV_10178511 ,

1. You can use: "GET /v3/trackers/{trackerId}/baselines" endpoint to obtain the list of baselines for each tracker.

2. To get all items in a baseline for a Project, you could use, for example, "GET" or "POST /v3/items/query" in combination with a "baselineId" and "queryString" like e.g. project.id IN (4).

Request body example:

{
"baselineId": 1234,
"page": 1,
"pageSize": 50,
"queryString": "priority='Normal'"
}

Best Regards,

Cristina
