post requests in python

Question

I want to do a post request in python with basic authentication AND token. I have already tested the post in postman and it worked but with python I always get status code 403.

For this API I have to do...

first fetch a token from the header with a GET request
use this token in header for POST request

auth = HTTPBasicAuth('User', 'Password')

token = requests.get(URL_token, auth=auth, headers={"x-csrf-token":"FETCH"}).headers['x-csrf-token']

requests.post(POST_url, data=json.dumps(test_data), headers={"x-csrf-token":token}, auth=auth)

The test_data are type of a list and again, in postman it works.

Is there something which I am doing wrong in the POST?

In Postman, your JSON payload as the body, but you're passing it data which is used for form data.

Therefore, try changing this line

requests.post(POST_url, data=json.dumps(test_data), headers={"x-csrf-token":token}, auth=auth)

to

requests.post(POST_url, json=test_data, headers={"x-csrf-token":token}, auth=auth)

requests.post does not have the keyword `body` – Christian Jul 10 '23 at 09:16
Extremely sorry, my bad, I mixed up between scrapy and requests, corrected it now. – Zero Jul 10 '23 at 09:18
the error code 403 still exists – Christian Jul 10 '23 at 11:00
403 means Forbidden, then you need to check if you're passing headers correctly like Bearer token and CSRF token, and anything else which is needed. – Zero Jul 10 '23 at 11:04

You have to do every step within a requests.Session():

s = requests.Session()
token = s.get(get_test_token, auth=auth, headers={"x-csrf-token":"FETCH"}).headers['x-csrf-token']
s.post(get_test_token, json=test_data, headers={"x-csrf-token":token}, auth=auth)
