What are Webhooks?
Webhooks are HTTP POST requests that bnplx.io sends to your application when payment events occur. Instead of checking payment status repeatedly, you’ll receive immediate notifications about status changes. Benefits- Real-time updates - Know instantly when payments are approved, captured, or refunded
- Reliable delivery - Automatic retries ensure you don’t miss critical events
- Reduced API calls - No need to poll for status updates
- Better user experience - Update your UI immediately when events happen
- Webhook endpoints must use HTTPS
- Never expose webhook secrets in client-side code
- Store webhook secrets securely in environment variables
| Environment | Webhook Endpoint |
|---|---|
| sandbox | https://api.staging.bnplx.io/webhooks/{merchant_id}/{merchant_connector_id} |
| Production | https://api.bnplx.io/webhooks/{merchant_id}/{merchant_connector_id} |
