401 error with OAuth2 token

[Yoonjung Cho]

I get 401 error with code below.

GOOGLE_APPLICATION_CREDENTIALS exported.

What would be a problem?

Thanks in advance.

(project id and token masked)

import requests
url = "https://translation.googleapis.com/v3beta1/projects/p*******3/locations/global:translateText"
token = "4/xAG_QxNqxN5IlNPx96ge******nM5mSmWt8lGZY0Zv-j1Wom196DFQ"
headers = {"Authorization": "Bearer " + token, 
        "Content-Type": "application/json; charset=utf-8"}        
data = {
  "model": "projects/p*******3/locations/global/models/general/base",
  "sourceLanguageCode": "en",
  "targetLanguageCode": "de",
  "contents": ["Come here!"]
}
res = requests.post(url, headers=headers, data=data)
print(res.text)

Response:

{
  "error": {
    "code": 401,
    "message": "Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
    "status": "UNAUTHENTICATED"
  } 

}

I solved the problem. What I used was a code, not access token. According to this document(https://developers.google.com/youtube/v3/guides/auth/installed-apps?hl=ko), I got access_token with code and it worked.

Hi,

Can you elaborate further on your solution? Perhaps as before, placing the entire code and obfuscating your credentials?

Best,

Hi Daniel, 

I believe he followed the instructions at [1] for obtaining OAuth 2.0 access tokens, but you can wait for elaboration from the original poster on his solution.
