Fixed: Problems with OAuth

Bugs & Features
1

I use python and using this script:

client_id = 'Hello' # I am using here my real id and client secret as mentioned in the tutorial
client_secret = 'World'

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

token = oauth.fetch_token(
    token_url='https://identity.dataspace.copernicus.eu/auth/realms/CDSE/protocol/openid-connect/token',
    client_id=client_id,
    client_secret=client_secret
)
resp = oauth.get("https://services.sentinel-hub.com/oauth/tokeninfo")
print(resp.content)

def sentinelhub_compliance_hook(response):
    response.raise_for_status()
    return response

oauth.register_compliance_hook("access_token_response", sentinelhub_compliance_hook)

And I still got this error:
oauthlib.oauth2.rfc6749.errors.InvalidClientError: (invalid_client) Invalid client or Invalid client credentials

I checked multiple times that I for sure have the correct id and secret and even recreated it, but still this error.

I am using this version:
oauthlib==3.2.2
requests-oauthlib==1.3.1

Found the error: Wrong link for token fetching.

Hello,
I’m having the same issue… What was the correct link for token fetching?
Thanks,

Hi @pauline.millet ,

For the Copernicus endpoint the token url is: https://identity.dataspace.copernicus.eu/auth/realms/CDSE/protocol/openid-connect/token.

For detailed configuration please refer to my colleague’s answer here and the Copernicus Data Space Ecosystem documentation.
