API charset=utf-8 remove

Hello all,
I have a little challenge with an API connection via postman everything works fine only via easymorph I can’t get it to work.
My problem is the charset=utf-8 I think. I am not so familiar with such a binding for this reason please help me.
Thanks in advance.

Hi @Sebastian_von_Borzyk

Based on your screenshot, the HTTP method PATCH is not allowed for this endpoint. Only POST, OPTIONS, HEAD, GET, and TRACE are supported.

Consider checking the Endpoint URL and API documentation.

Thanks for the quick help.
I have contacted the manufacturer of the software. There is an error in the API.
Thank you for the help
