How to Generate Bearer or Access Token in Azure AD B2C Custom Policies (With Answer)

Question

Introduction

In this post, I will share how to configure Azure AD B2C Custom Policies to dynamically generate a bearer or access token using a token endpoint. This is particularly useful for scenarios where you need to authenticate with a third-party system or API and retrieve dynamic access tokens.

Why This is Useful

• Simplifies API authentication by automating token retrieval.
• Makes it easy to integrate with systems requiring OAuth 2.0 authentication.
• Enhances the capabilities of Azure AD B2C Custom Policies for advanced scenarios.

Key Concepts

1. Claims and Technical Profiles: Define claims to hold required values (e.g., client_id, client_secret) and use a Technical Profile to call the token URL.
2. Service URL: Points to the OAuth token endpoint, typically in the format: `https://login.microsoftonline.com/
