Backend Workflow, Request Using Python

Need help APIs
1

I’m currently working on sending a request to a backend workflow through python and this is what i currently have worked out:
response2 = requests.post(f"https://www.{url}.com/api/1.1/wf/{backendworkflowname}", headers=headers, params=data2)
print(response2)
This is only a snippet of the code, and every variable is assigned.
However, that request returns 405, even though the contact method is POST and it is sending a POST request.
