Change Shape Of The Custom Connector Response

(0) ShareShare
ReportReport
Posted on by mdevaney 29,987 Super User 2025 Season 1
I built a custom connector whose default response is a nested JSON object (left-side) but I want to make it look like the JSON object on the right-side:
 
  • Remove nesting
  • Rename keys to my own preferred names
  • Change text to numbers for some pairs
Is there a way to shape a custom connector response?  I am willing to write code in other languages to do it.

    I figured out how to transform the response using some C# code and detailed the steps on my blog:

    While we expect your API to do any type of transform and use connector as a pass through, we released a new feature yesterday that will allow you to write custom code: https://docs.microsoft.com/en-us/connectors/custom-connectors/write-code

    @Syndicate_Admin 
    I would prefer to code the connector so it gives the desired JSON object instead.  Is this possible?
