# source on POST /v2/notes/search stops working

Calls to POST /v2/notes/search, body parameter data.source on Productboard API stopped working on April 14, 2026.

On April 14, 2026, the body parameter data.source on POST /v2/notes/search was removed. Calls that include this parameter fail since that day. The change removes deprecated legacy flat properties from the request body.

## What to use instead

Send the notes filters in the structured data.filter and data.return objects instead, such as data.filter.id, data.filter.fields.*, data.filter.metadata.*, data.filter.relationships.*, data.filter.createdAt, and data.filter.updatedAt.
