I can not add Entities over the API

[Andorxor]

Whenever i try to add a entity over the API i get the following error in the log:

API [POST]:/:controller, Params:Array (     [controller] => Account ) , InputData: {"assignedUserId":"system","name":"XTestX"} -  [] []
Display Error: , Code: 400 URL: /CRM/api/v1/Account [] []

Hello.
Error 400 means BadRequest. You have an incorrect parameter. Also, check this https://www.espocrm.com/documentation/development/api/.

I made a entity with only name as required field and got a 400 when i tried to create it with {"name":"test"} as payload.

Also, you have to define the all fields with the 'required' status.
