I’m struggling to authenticate using an Azure AD B2C tenant. Despite trying various approaches, I’ve yet to succeed. A promising method involved using the OAuth2 API with the Authorization Code grant type. However, this requires a code_challenge, which appears to be unsupported in N8N. Has anyone successfully connected to Azure AD B2C?

Hi @akarray 
Welcome to the community

Hello, Yes I find a solution. Thank you
