Pass through an identity provider's access token in Azure AD B2C
Published date: August 15, 2019
It's now easier for an Azure AD B2C application to leverage the power of social identity providers and their APIs. When a user signs in using an identity provider, your application can now get the identity provider's access token passed through as part of the Azure AD B2C token. You’ll be able to use this access token when you call the identity provider’s API.
