This is a community maintained collection of samples for scenarios enabled by API connectors for Azure AD B2C 'built-in' user flows.

As a developer or IT administrator, you can use API connectors to integrate your sign-up and sign-in user flows with web APIs to customize the user experience. For example, with API connectors, you can:

• Validate user input data. Validate against malformed or invalid user data. For example, you can validate user-provided data against existing data in an external data store or list of permitted values. If invalid, you can ask a user to provide valid data or block the user from continuing the sign-up flow.
• Integrate with a custom approval workflow. Connect to a custom approval system for managing and limiting account creation.
• Overwrite user attributes. Reformat or assign a value to an attribute collected from the user. For example, if a user enters the first name in all lowercase or all uppercase letters, you can format the name with only the first letter capitalized.
• Perform identity verification. Use an identity verification service to add an extra level of security to account creation decisions.
• Run custom business logic. You can trigger downstream events in your cloud systems to send push notifications, update corporate databases, manage permissions, audit databases, and perform other custom actions.
• Augment tokens. Enrich tokens for your sign-in and sign-up user flows with attributes from legacy identity systems, custom data stores, and other cloud services.
