Hi @Daniel Domingues , Azure AD B2C does not provide features to upload files; Azure Storage does. So you would have to utilize another Azure product for this. Azure AD B2C is for user identities, which provides information to Azure Storage about who is/can upload files. Please let me know if you would like me to show you how you can do this. Please tell me more about your use case so I can cater it to your cause. Please let me know if you have any questions or if I misunderstood yours.
