Dynamic UI Orchestration: Using the Services List API to Manage Frontend Verification Options

Building a robust registration or verification flow requires more than just collecting user input; it requires knowing exactly which verification services are available at any given moment. Hardcoding your UI to support specific platforms can lead to broken user experiences if a service becomes temporarily unavailable or if your account configuration changes.

By leveraging the Services List API, you can build a dynamic frontend that adapts to your current service availability in real time.

Understanding the Integration Boundary

The GET /v1/services endpoint is your source of truth for service availability. Instead of manually updating your registration form when you add or remove support for a platform, your application can fetch the current list of enabled services and render the appropriate input fields accordingly.

The Data Contract

When you query the API, you receive a list of services, each defined by its type, the required data_type (phone or email), and an enabled boolean flag.

// Conceptual representation of the API response
{
 "success": true,
 "services": [
 { "type": "facebook", "data_type": "phone", "enabled": true },
 { "type": "netflix", "data_type": "email", "enabled": true }
 ]
}

Implementation Strategy

To ensure your UI remains resilient, follow these steps:

1. Fetch on Initialization: Trigger a request to /v1/services when your application initializes or before rendering the registration component.
2. Filter by State: Only iterate over services where enabled is true.
3. Map to UI Components: Use the data_type field to determine whether to render a phone input or an email input.

Testing and Sandboxing

When building this integration, it is critical to test how your UI handles different API states. Use fixture files to simulate various responses from the API:

• Happy Path: A response containing a mix of phone and email services.
• Partial Outage: A response where specific services have enabled: false.
• Empty State: An empty services array to ensure your UI gracefully handles a scenario with no available verification methods.

By mocking these responses in your local test environment, you can verify that your logic correctly toggles input visibility without making actual network calls during development.

Important Considerations

When integrating, keep in mind that the API has rate limits that restrict requests per minute and that concurrency is also limited. Always consult the official API documentation for the most current information regarding these limits to ensure your application remains stable under load.

Conclusion

Dynamic UI orchestration allows you to decouple your frontend logic from your backend service configuration. By treating the Services List API as the primary source for your UI state, you create a more maintainable and reliable verification experience for your users.
