Decision Record: Implementing Proactive Balance Management for Synchronous Telegram Checks
When building a contact-cleansing pipeline that relies on synchronous Telegram registration checks, managing your account balance is as critical as handling network latency. Because the service operates on a pay-per-check model with automatic refunds for failed or undetermined results, developers must ensure their orchestration logic does not stall due to insufficient funds.
The Challenge: Synchronous Batching vs. Account State
The Telegram registration check API supports synchronous batch processing of up to 100 identifiers per request. While this is efficient for throughput, it introduces a boundary condition: if a batch request is submitted when the remaining account balance is lower than the cost of the batch, the request will fail.
To maintain high availability in your data pipeline, you must decide between two strategies:
- Aggressive Batching: Sending the maximum allowed identifiers (100) per request.
- Adaptive Incremental Processing: Dynamically adjusting batch sizes based on real-time balance checks.
The Recommended Approach: Proactive Balance-Aware Orchestration
For most production pipelines, we recommend an Adaptive Incremental approach. By querying your account balance via the dashboard or API before initiating a large batch, you can create a "go/no-go" gate.
Implementation Checklist
- Pre-flight Balance Check: Before triggering a batch, verify that your current balance covers the intended volume. If the balance is insufficient, reduce the batch size or trigger a top-up alert.
- Error Handling: Always implement robust logic to handle specific error codes related to balance insufficiency. If a request returns an error indicating insufficient funds, the system should pause further requests to prevent cascading failures.
- Rate and Concurrency Awareness: The API has rate limits that restrict requests per minute and concurrency is also limited. Consult the current API documentation for applicable limits, as exceeding these will lead to rejections that do not consume your balance but will interrupt your pipeline flow.
- Graceful Degradation: If your balance is low, switch to single-number checks or smaller batches to maintain continuity while your replenishment process completes.
Operational Boundaries
It is important to note that the API is synchronous. A request returns the result (or an error) in the same HTTP response. Because the system automatically refunds failed or undetermined checks, your balance management logic does not need to account for "lost" credits from unsuccessful attempts.
Final Takeaway
Do not treat account balance as a static configuration value. By integrating a balance-check gate into your orchestration layer, you prevent the "insufficient balance" error state from blocking your pipeline. Always prioritize checking your current API documentation for the most accurate rate and concurrency limits to ensure your implementation remains within the service's operational boundaries.
