Hi,
I am trying to create a custom connector to Zendesk in order to add it to an app. the below screenshot is from postman which I can get the result that I need

"user": {
"id": ID,
"url": "https://URL/api/v2/users/ID.json",
"name": "Required info",
"email": "required info",
I was wondering what is the best way to be able to create the custom connector so I can pass the USERID as a variable and get the result inside the app.
Any help is much appreciated
