Can I retrieve app name based on some custom attribute value using developer apps API ?

[Ragava1]

Example:

GET /organizations/{org_name}/developers/{developer_email}/apps/{attribute_name}/

Not directly, unfortunately. The query capability of the Apigee API is pretty limited. 

The way I would do it is "brute force" - just query each app and look for the matching attribute.
