An Azure service that provides a hybrid, multi-cloud management platform for APIs.
Welcome to Microsoft Q&A! Thanks for posting the question.
I see that you are doing a POST request against the management URI. Can you please change the method to GET instead and try. Please refer to the doc here for more details, which specifies GET method for performing this operation.
I did a sample test using REST Client extension in VS Code against the management URI and got the expected result when using GET as specified in the documentation. For POST, i see a 404 returned.
Please me me know if you have any questions.
