Mota, Adrian (extern DSS) Visan, Nicolae We appreciate the additional context you provided. At the moment, GraphQL in APIM only supports POST requests for sending the query in the body and query string parameters. Unfortunately, GET requests are not supported and we have a backlog item to support this feature but no ETA available at the moment.
We value your feedback and ideas, so please feel free to submit your use case via https://aka.ms/apimwish. Others with similar interests can upvote your idea too and this will help us prioritize the features. I hope this helps with your question and let me know if you have any.
If you found the answer to your question helpful, please take a moment to mark it as "Yes" for others to benefit from your experience. Or simply add a comment tagging me and would be happy to answer your questions.
