Hello,

We have started using the wikimedia-android-data-client library( https://github.com/wikimedia/wikimedia-android-data-client) to make mediawiki api calls in the Commons Android app, replacing the legacy library that we were using previously. Most of the authenticated calls (i.e. login, upload, nomination for deletion, thank, notifications etc) made to Commons wiki are working with the new library, but we are stuck with a cross-wiki call to Wikidata. We are trying to call `Service:wbcreateclaim` to create a claim on Wikidata but the call is failing.

We have posted relevant http logs at https://github.com/wikimedia/wikimedia-android-data-client/issues/21#issue-4...

We would greatly appreciate it if could take a look at the logs and suggest what we might be doing wrong. Is it because of some issue with cookies? Because as far as we can see, as expected we are sending the params in POST request body with application/x-www-form-urlencoded.

Relevant code: https://github.com/commons-app/apps-android-commons/blob/backend-overhaul/ap...

Relevant method call: service.postCreateClaim(entityId, snaktype, property, value, "en", csrfTokenClient getTokenBlocking())

Thank you so much!

Best regards, Josephine
