A redwing-marsh mobile app must prove it subscribed to a protected APIM product. What credential does the app send on each call?
Select an answer to reveal the explanation.
Short Explanation
Protected product means subscription key—after the redwing-marsh app subscribes, send that key on every call (header or query).
Full Explanation
Subscription keys are the default API Management access model for protected products. After a developer subscribes, callers include the key in a header or query string as documented. Graph directory roles, management-plane tokens, and storage account keys are not the product subscription credential.
