How to Integrate Telegram Number Checks into Synchronous Identity Workflows

When building user onboarding flows, verifying that a provided phone number is associated with an active Telegram account is a common requirement for fraud-prevention logic. By integrating account-presence signals directly into your registration pipeline, you can gather supporting data points to inform your internal risk-scoring rules.

The Role of Account Presence Signals

It is important to remember that a "registered" signal from a platform check serves as an indicator of account presence. It should be treated as a supporting data point for your customer-defined decision logic rather than a universal guarantee of user legitimacy or intent.

Choosing Your Integration Path

When deciding how to implement these checks, consider the following trade-offs:

• API Integration: Best for automated, synchronous workflows where you need to ingest signals programmatically during the user's registration journey.
• Named Checker Products: Suitable for ad-hoc verification or specialized checks where you need to target a specific platform.
• CSV/Bulk Uploads: Not supported for this product. All verification must be performed via the documented API interfaces to ensure consistent, synchronous processing.

Step-by-Step Integration Guide

Follow these stages to incorporate Telegram verification into your backend services.

1. Configure Your Service Combo

Before making your first call, define which services you need to verify. Using the Combo Check API allows you to verify multiple platforms simultaneously. You can configure your preferred services via the dashboard, or override them dynamically per request.

2. Implement the Synchronous Request

Use the /v1/check/combo/phone endpoint to submit an E.164 formatted phone number. Ensure you include your X-API-Key in the request headers.

// Conceptual request structure
{
 "identifier": "+1234567890",
 "service_types": ["telegram"]
}

3. Handle the Response

The API returns a synchronous response containing the registration status for each requested service. If a service check results in a null value, it indicates that the presence could not be determined for that specific identifier at the time of the request.

4. Integrate into Decision Logic

Map the registered boolean to your internal risk engine. For example, if your policy requires a verified Telegram account for specific high-value actions, you can use the returned signal to flag the account for manual review or secondary verification steps.

Conclusion

Integrating platform-specific signals like Telegram registration allows you to build more context-aware onboarding flows. By treating these signals as inputs for your internal risk-scoring rather than binary trust markers, you can effectively balance user friction with your security requirements.
