Asynchronous calls, polling vs Webhooks

Asynchronous calls, polling vs Webhooks

When data is updated on the external system side, it is important to get it in time and without unnecessary load on the server. API integrations use two approaches for this: polling and webhooks. We support both methods and help you choose the best one for the task: regular polling is suitable for non-critical data, awebhooks - for instant response to events.

This flexibility allows you to save resources, increase stability and quickly respond to any changes in the external system.

Comparison of approaches

Method	Benefits	Application Features
Polling	Simple implementation, no need to accept requests	Polling an external API at a given interval
Webhooks	Instant response, no unnecessary traffic	The external system itself sends a notification

How we implement

Polling via CRON, queues, deferred tasks
Webhooks with Secure Endpoints, Signature Validation (HMAC)
Polling interval control, repeat deduplication
Security: tokens, IP filtering, retry on errors
Logging events: who, when, with what payload and result

Webhook Event Examples

Payment receipt notification
Confirmation of KYC or registration
End of session, bet, win
Update player or balance
Email/SMS delivery statuses

Integration benefits

Quick reaction to external events
No API overload with unnecessary requests
Flexible retry/timeout configuration
Compatibility with providers (Stripe, Telegram, Meta, etc.)
Centralize notification processing logic

Where especially important

Payment platforms and financial gateways
iGaming platforms with real-time events
Marketing Services and Email Integration
Systems with large amounts of dynamically changing data

Polling or Webhooks - choose the best for the task. We implement both schemes with strong security, logging and scalable architecture to make your API work efficiently and without delay.
