@muobeidat can you help me with testing the APIs?

[hishamco]

I started testing the APIs with the help of .http file

I would move every request to it's own file similar approach to all of the existing endpoint we already have. Here is an example https://github.com/OrchardCMS/OrchardCore/blob/main/src/OrchardCore.Modules/OrchardCore.Contents/Endpoints/Api/CreateEndpoint.cs

There is no need for IEndpoint interface. Also there is not need MapMediaApi extension since you can just register that once in the Startup using the same approach here https://github.com/OrchardCMS/OrchardCore/blob/main/src/OrchardCore.Modules/OrchardCore.Contents/Startup.cs#L216-L218

First of all, it's still WIP PR :)

I saw what you have done before. TBH, I don't like to have every request in each file unless it's needed, like what I have, because there are many lists, create methods

There is no need for IEndpoint interface

I introduced the interface for a reason, but the PR is still incomplete. Then I will check if it will be needed or not

We should group things by type and not actions, like FolderEndpoints instead of DeleteEndpoints.
