How to impement URL rewrite on Azure

Question

I have an app that integrates to CRM on-premise through azure. The app references the latest version of CRM API (v9.0 and v9.1) whilst our client has a lower CRM API version (v8.2).

The app calls a URL as follows:
https://app1.msappproxy.net//api/data/v9.1/contacts?$select=fullname,telephone1,address1_composite&$filter=contains(fullname,%27Test%27)

We would like to rewrite the v9.1 to v8.2. to get the below URL called.

https://app1.msappproxy.net//api/data/v8.2/contacts?$select=fullname,telephone1,address1_composite&$filter=contains(fullname,%27Test%27)

Answer 1

URL Rewrite is available through Azure Application Gateway or Azure Front Door. These services would need to be placed in front of the application receiving the request, and the URL Rewrite can be performed.

As a disclaimer, it is likely easier to just change the request to the correct version at the source.
