How to add http headers along with data to send a POST request to an API endpoint using Oauth2Session (requests_oauthlib)?

I have a python code like this to interact with an API

from oauthlib.oauth2 import BackendApplicationClient
from requests_oauthlib import OAuth2Session
import json
from pprint import pprint

key = "[SOME_KEY]"          # FROM API PROVIDER
secret = "[SOME_SECRET]"    # FROM API PROVIDER

api_client = BackendApplicationClient(client_id=key)
oauth = OAuth2Session(client=api_client)

url = "[SOME_URL_FOR_AN_API_ENDPOINT]"
# GETTING TOKEN AFTER PROVIDING KEY AND SECRET
token = oauth.fetch_token(token_url="[SOME_OAUTH_TOKEN_URL]", client_id=key, client_secret=secret)

# GENERATING AN OAuth2Session OBJECT; WITH THE TOKEN:
client = OAuth2Session(key, token=token)
body = {
    "key1": "value1",
    "key2": "value2",
    "key3": "value3"
}
response = client.post(url, data=json.dumps(body))
pprint(response.json())

When I run this py file, I get this response from the API, that I have to include the content type in the header. How do I include the header with Oauth2Session?

{'detailedMessage': 'Your request was missing the Content-Type header. Please '
                    'add this HTTP header and try your request again.',
 'errorId': '0a8868ec-d9c0-42cb-9570-59059e5b39a9',
 'simpleMessage': 'Your field could not be created at this time.',
 'statusCode': 400,
 'statusName': 'Bad Request'}
Solution

  • Have you tried to you send a header paramter with this requests?

    headers = {"Content-Type": "application/json"}
response = client.post(url, data=json.dumps(body), headers=headers)
