Reporting API rejects ad hoc segments after upgrade
1 source thread · first seen 2026-10
Summary
After upgrading to Matomo 5.14.x, reporting API calls using ad hoc segments return an error unless each segment is first created in the Segment Editor. The reporter needs date-specific segments that change daily, making pre-creating them cumbersome.
- Affects
- Teams retrieving visitor data through the Reporting API
- Workaround
- Create each segment manually in the Segment Editor or programmatically with SegmentEditor.add, then wait for its data to be pre-processed.
