Integrations

Event-driven workflows

Webhooks, message queues, pub/sub, retries, idempotency, dead-letter queues, and reconciliation. Handle duplicate messages and partial failures without quietly corrupting business records.

Discuss your project

An event may arrive more than once

order.created / event-42

First delivery → apply once

order.created / event-42

Repeat delivery → recognize prior processing

order.updated / event-43

Missing dependency → hold or retry

Queues and webhooks decouple systems, but they also make time and ordering visible. Consumers need explicit behavior for duplicate, delayed, and out-of-order messages so a delivery problem does not become a corrupted record.

Build the recovery lane with the happy path

01
Validate
Check the event schema and source.
02
Attempt
Apply an idempotent business operation.
03
Retry
Use bounded attempts for transient failures.
04
Escalate
Retain the failed event and its diagnostic context.

What belongs in a replay procedure?

Define which messages may be replayed, who can authorize it, and how the system recognizes previously applied effects. Review the reconciliation result after replay.
