User Problem

Currently, retrieving Custom Fields via API calls for multiple Work Items simultaneously is not possible. Custom Fields can only be fetched by specifying the Work Item ID in the API call, which means they must be retrieved one at a time. It would be beneficial to have the capability to retrieve Custom Fields using Filter and Select parameters on GET API calls.

Suggested Solutions

At present, the only potential solution to this would be to create a script that makes "n" calls based on the number of Work Items. There are no other suggested solutions available at this time.

Current Workarounds

As of now, there are no known workarounds for this issue.
