REST API remove/delete SP User from Group

Hello together,

i like to remove a SharePoint User from a SharePoint Group with a SharePoint Workflow with the REST API.

With a workflow i can already create users over the rest api in groups.

But i could not find any helpful post which gives me a howto for delete users from a group.

I am using the designer 2013 for creating. Is there a option for delete users?

Please help me.

I found this informations:

URL:

https://URL/subsite/_api/Web/GetUserById(17)/Groups"

headers:

accept: application/json; odata=verbose

content-type: application/json; odata=verbose

IF-MATCH: *

X-HTTP-Method: DELETE

FUNCTION:

http requst: POST

What is wrong?

Thanks
