Webhooks

Webhooks allow PrintPrice to notify external systems when important events occur inside the platform.

They provide a push-based integration model for automation and orchestration.

Purpose​

Webhooks are used to transmit event-driven updates such as:

  • document analyzed
  • pricing completed
  • compatibility evaluated
  • routing decision created
  • order generated
  • processing failed

This allows connected systems to react in near real time.

Event Model​

Each webhook should represent a clearly defined event type.

Typical event payloads may include:

  • event name
  • event timestamp
  • entity identifier
  • environment
  • structured event data

This makes downstream processing easier and more reliable.

Delivery Principles​

Webhook delivery should be:

  • authenticated
  • signed where possible
  • retryable
  • idempotent-aware
  • observable

These principles reduce integration fragility.

Security​

Webhook endpoints should verify that incoming requests are legitimate.

Recommended protections include:

  • shared secret signatures
  • timestamp checks
  • replay attack protection
  • strict payload validation

This is especially important when webhooks trigger downstream operational actions.

Retry Strategy​

Webhook delivery may fail due to temporary network or application issues.

A robust webhook model should support retries with controlled backoff.

This increases reliability without overwhelming receivers.

Idempotency​

Receivers should assume that the same event may be delivered more than once.

For that reason, webhook consumers should process events idempotently whenever possible.

This prevents duplicate side effects.

Observability​

Webhook flows should be observable across the platform.

Useful telemetry includes:

  • event count
  • delivery success rate
  • retry count
  • last delivery attempt
  • endpoint error patterns

This supports integration debugging and operational trust.

Typical Consumers​

Webhook consumers may include:

  • order systems
  • CRM tools
  • workflow automation platforms
  • production dashboards
  • partner systems

As the platform grows, webhook-driven integrations become increasingly important.

Long-Term Evolution​

Future webhook capabilities may include:

  • partner-specific subscriptions
  • filtered event streams
  • retry dashboards
  • dead-letter handling
  • delivery audit logs
  • event versioning

These patterns help support a mature multi-party production ecosystem.
