Choosing your approach
Recommendation
Always provide acallback_url in your deposit and withdrawal requests. Webhooks deliver results within seconds of the payment settling — polling introduces latency and unnecessary load.
If your callback endpoint is temporarily unavailable, winam-payments retries 3 times with exponential backoff. After all retries are exhausted, use Replay Webhook to re-deliver the notification manually.
See Webhooks for payload format and signature verification.
