Rest API - Handling multiple records in Response

Content

Hi,

How to handle the multiple rows in the Rest API response?

Use Case: When we enter the Dept, the user should see all the employees associated with the Dept. 

Tried below options.

Collection - This option is not useful, since we could not pass (find) the parameter dynamically.

Action - We could not map the head -> item (i) -> Data1 value into variable, 

Thanks,

Mohan
