I am trying to change one value from a JSON GET Payload and PUT a response back. Fulcrum requires the full JSON payload to be sent back or the data is erased. All I am trying to do is change the field value 71ca to a response (Primary Key value) after posting some data into our databse. I have everything working except how to change the value of 71ca. I tried pass through mode but that just passes all the data. I am sure I missing something simple with all the zapier step options.
