Create custom entity using REST API

Hello,

I'm in the process of trying to create a custom entity using the REST API.

I went through the documentation, or lack thereof, and found out that I can get all entities by doing a GET request to https://{MS Dynamics URL}/api/data/v9.2/entities

After this I figured that I could create an entity by doing a POST to the same endpoint mimicking an entity from the get all request, but it seems to return this error:

{
    "error": {
        "code": "0x80040800",
        "message": "The 'Create' method does not support entities of type 'entity'. MessageProcessorCache returned MessageProcessor.Empty. "
    }
}

Is it actually possible to create custom entities using the REST API? and if so, could someone point me in the direction of the documentation.

Thanks in advance,

Hi,

Please try below suggestion:

1. Create custom api and register plugin on it.

2. In plugin write a logic to create custom table using below link:

https://learn.microsoft.com/en-us/power-apps/developer/data-platform/org-service/create-custom-entity

3. Call this custom api from your application.
