ERP Integration Services: Fixing Event Order

说明与用途

文章说明如何通过使用 outbox 模式、明确的业务事件建模和幂等工作者来修复 ERP、仓库和 CRM 集成中的一致性问题。

问题

ERP integration services returned successful API responses while the business workflow remained incorrect, leading to inconsistent system states and manual reconciliation.

结果

By separating business events from API calls, persisting events locally, and making workers idempotent, the integration achieves reliable ordering and consistency across ERP, warehouse, and CRM systems.

工作流

• 1. Receive order and trigger business event sequence rather than inline API calls.
• 2. Persist order and corresponding business event in a local outbox table within a single transaction.
• 3. Dispatch events to external systems asynchronously via workers.
• 4. Ensure workers are idempotent by marking events processed and enforcing uniqueness in the database.
• 5. Use webhooks for notifications but keep workflow ownership in the worker logic.

证据

The order reached the ERP. The warehouse received the inventory request. The CRM received the customer update. Every HTTP call returned 2xx.

The application then commits the order and event together:

ERP Integration Services should treat duplicate delivery as a normal condition.
