Hi David,

Thanks a lot for your answer.

We can now obtain all required data like this: https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q78&format=json

The result contains the labels organised by language tags and geo data (P625) that we need as well. This is great!

I was also able to create a OAUTH 2.0 token (linked to my user).

What did not work, was token refreshing (https://www.wikidata.org/wiki/Wikidata:REST_API/Authentication#Non-owner-only_clients).

I tried this:

 curl --request POST \                                                                        

  --url https://www.wikidata.org/w/rest.php/w/rest.php/oauth2/access_token \

  --header 'Content-Type: application/x-www-form-urlencoded' \

  --data grant_type=client_credentials \

  --data client_id=abc \

  --data client_secret=xyz

I get the following response:

{"messageTranslations":{"en":"The requested relative path (/w/rest.php/oauth2/access_token) did not match any known handler"},"httpCode":404,"httpReason":"Not Found"}

Any idea what I am doing wrong?

Thanks again and kind regards,

Tobias
