Real-Time Updates with Webhooks
A practical guide to using NoPOS webhook endpoint management and delivery history in integrations.

NoPOS Team
Developer Relations
The NoPOS developer relations team writes practical guides for building on the NoPOS REST API — from first smoke test to production POS.
Webhooks help external systems react when operational data changes. NoPOS includes webhook endpoint management, delivery tracking, and test delivery routes in the developer catalog.
Build defensively
- Store every received event ID.
- Make handlers idempotent.
- Verify signatures when configured.
- Retry safely and alert on repeated delivery failures.
- Keep a manual replay path for support.
Developer workflow
- Create or configure the webhook endpoint from the NoPOS API.
- Send a test delivery.
- Confirm your receiver stores the event and returns a 2xx response.
- Monitor delivery history before enabling the integration for production.
Use Swagger UI or OpenAPI for the current webhook request and response shapes.
