Azure Data Factory

Question

Good afternoon, I require your support in resolving this issue. I am performing a copy in Data Factory from an HTTP request. The JSON being retrieved has a nextLink, but I have tried configuring it according to Microsoft's documentation, and it keeps making queries for a long time without finishing. Any advice would be greatly appreciated.

In the attached image "JSON", you can observe the key-value field 'nextPageKey' that I need to capture for the query to continue. When the query ends, the field still appears but is NULL.

With the value of the 'nextPageKey' field, a new URL is constructed. The original URL is https://xxxxxxxxxx.live.dynatrace.com/api/v2/metrics, and then this information should be appended to the original URL: https://xxxxxxxxxx.live.dynatrace.com/api/v2/metrics?nextPageKey=information form the json file"

Thanks
