Where can I obtain my Azure AD B2C Issuer URL in the Portal

Question

Currently trying to configure "Advanced" authorization/authentication for my Azure Functions using an Azure AD B2C directory. In order to do so it is stating that I need an issuer URL:

When I navigate to the app that I've set up in Azure AD B2C and select endpoints, I am presented with several urls, however it is unclear to me which one represents the "Issuer URL". Also what should be put in place for "policy-name". I've set up a user flow for login, but would this also support client credentials flow?:

Answer 1

It should be this format:

https://{tenant}.b2clogin.com/{tenant}.onmicrosoft.com/v2.0/.well-known/openid-configuration?p={policy name}

Select any of your user flows or custom policies and you will see this URL at the top of the blade.

Answer 2

policy-name is the user flow name. You can use it is in the Endpoints.
