# owners on POST /v2/entities/search stops working

Calls to POST /v2/entities/search, body parameter data.owners on Productboard API stopped working on April 30, 2026.

On April 30, 2026, the Productboard API removed the legacy body parameter data.owners from POST /v2/entities/search. Requests sending this parameter fail since that date. The change permanently disables this flat property along with several other legacy request body properties.

## What to use instead

Send entity filters using the structured data.filter and data.return objects instead, including data.filter.type, data.filter.id, data.filter.fields.*, data.filter.relationships.*, and data.return.fields. Moving to these structured objects requires updating your request payload structure beyond changing a single field name.
