DFF created but not showing when extracting through API

Summary:

Receivables-Customer DFF created but not showing when extracting through API

Content (please ensure you mask any confidential information):

We created a DFF in Receivables-Customer at the Organization level, hoping to extract the customer through a query parameter in a REST API call. The DFF and its value are showing in the UI and in BIP, but not in the REST API response payload.

Has anyone encountered the same issue and resolved it? What were the steps you needed to do to enable the DFF in the REST API response?
