Hi all,
I want to set up an oauth2 API call to battlenet (blizzard)
The setup is as follows:

When running the workflow (API) I get the following error:
Where Callback URL is : http://website_name.gg/version-test/index/debug_mode=true
and the URL where the call comes from is : http://website_name.ggversion-test/index/sample:user?debug_mode=true
First thing I noticed is the part in the url /sample:user? - where does this come from ? Does this need to be in the call back url? I guess not because the API response should send the user?
Is something wrong in the settings in bubble (in my settings)?
Thank you very much for your help! This is the last feature to finish before launch so I really need your help
