Use this page to quickly see which events Blaaiz emits and what every webhook payload contains.

Event types

Payout events

  • payout.initiated — Payout has been created
  • payout.processing — Payout is being processed
  • payout.completed — Payout completed successfully
  • payout.failed — Payout failed

Collection events

  • collection.initiated — Collection request created
  • collection.pending — Awaiting customer payment
  • collection.completed — Payment received successfully
  • collection.failed — Payment failed

Customer events

  • customer.created — New customer created
  • customer.verified — Customer KYC verified
  • customer.rejected — Customer KYC rejected

Virtual account events

  • virtual_account.created — Virtual account created
  • virtual_account.credited — Funds received in virtual account

Payload structure

All webhook payloads include:
  • event — The event type
  • data — The event data object
  • timestamp — When the event occurred
  • signature — HMAC signature for verification (header: x-blaaiz-signature)
Always verify the x-blaaiz-signature to ensure the webhook originates from Blaaiz.

Webhook retries

We retry deliveries with exponential backoff and jitter to avoid thundering herds.
  • Attempts: up to 10 total
  • Initial backoff: 5 minutes
  • Backoff factor: 2x per attempt
  • Max backoff cap: 24 hours (1440 minutes)
  • Jitter: 80–120% randomization on each delay
  • Success: any HTTP 2xx response stops retries
  • Any non-2xx (4xx/5xx/timeout/connection error) triggers the next retry
Approximate schedule (actual delays vary ±20% because of jitter):
AttemptApprox. delayCumulative time
1Immediate0
2~5 minutes~5 min
3~10 minutes~15 min
4~20 minutes~35 min
5~40 minutes~1.25 hours
6~80 minutes~2.5 hours
7~160 minutes~5 hours
8~320 minutes~10 hours
9~640 minutes~21 hours
10~1280 minutes~42 hours
After 10 failed attempts, the webhook is marked permanently failed and no further automatic retries occur. You can manually replay via the API.
⚙️ Best practices
  • Reply with a 2xx quickly (within 30 seconds) and process work asynchronously if needed.
  • Implement idempotency using the event_id so duplicate deliveries don’t double-process work.
  • Return non-2xx only when you truly want a retry.

Data retention

Webhook logs (payloads, responses, attempt history) are retained for 90 days. After 90 days, records are pruned for both successful and failed deliveries.
  • If you need webhook data beyond 90 days, store it in your own systems.
  • Replay is only available for webhooks within the 90-day window.
