With Azure API Management can you hide Try me function for API and limit product subscription count

APIM uses different controls for these requirements. For anonymous visitors, the managed developer portal can redirect anonymous users to sign-in from Developer portal > Identities > Settings. Limit product and page visibility to selected user groups. The built-in API reference owns Try it, so no simple product switch hides only that control from a signed-in nonsubscriber. Use access-controlled page sections or a custom widget; self-hosting is the option when core portal behavior must be changed. Regardless of visibility, protect the API itself: enable Requires subscription on the product, and use OAuth or another gateway policy when stronger authorization is needed. Hiding a button is not an access control. To prevent duplicate subscriptions, edit the product and set Subscription count limit to 1. Optionally enable Requires approval. Test with an anonymous browser, a signed-in nonsubscriber, and a subscriber before republishing the portal.
