How to use JSON on POST in Python Requests

How I can use this JSON Data on POST

{"data":"{\"email\":\"anything65@gmail.com\",\"agreedToTerms\":true,\"profile\":{\"profileTypeID\":1,\"agreedToTerms\":true,\"firstName\":\"name\",\"lastName\":\"dfghjefws\",\"errors\":{}}}"}

This is My currently code, I got every time "message: Server Error"

data_profile2 = {"data":"{\"email\":\"anything65@gmail.com\",\"agreedToTerms\":true,\"profile\":{\"profileTypeID\":2,\"agreedToTerms\":true,\"firstName\":\"name\",\"lastName\":\"dfgh jefws\",\"errors\":{}}}"}
reqeust_1 = session.post(url_profile,headers=headers_profile, json=data_profile2)

Solution

requests doc

POST request

import requests

payload= {"data": {"email": "anything65@gmail.com", "agreedToTerms": True , "profile": {"profileTypeID": 1,"agreedToTerms": True, "firstName": "name", "lastName": "dfghjefws", "errors": {}}}}
request_1 = requests.get(url_profile, headers=headers_profile, data=payload)

update

If you use json=payload, your Content-Type in header will be application/json automatically. I assume that a session is not mandatory for that you want to do. Sessions persist parameters across many requests.
