Hi @Manuel Heye ,
Thanks for reaching out.
I understand you are trying to get the Azure AD B2C token to retrieve oid.
Unfortunately, it is not possible to authenticate the user without required parameters. These parameters specify what type of token is being requested to use by proper audience.
To get the token, you need to call authorize endpoint with the required parameters which will provide you authorize code to redeem the token from the /token endpoint.
