Hi,
After doing some research on how to consume Retail server APIs using external application, I found this Microsoft documentation link https://learn.microsoft.com/en-us/dynamics365/commerce/dev-itpro/consume-retail-server-api#register-the-application-in-azure-app-registration that explain the steps to do this, and I found this video tutorial https://www.youtube.com/watch?v=VjbLr0BB4AE created by Huzaifa Gain
The difference that I noticed in the steps to follow is that in the video I see the creation of just one App registration in Azure portal which is the app registration for the client, but in the Microsoft link I see that we need to create two Apps registration (one for the retail server and the other for the client) and I don't understand why we need the App registration for the retail server as long as we can do this integration using just the app registration for the client like mentioned in the video
each answer is appreciated
best regards
