## What you need to know

### How should ecommerce integrations be migrated?

Document each integration’s contract, credentials, data flow, identifiers, timing and failure behavior. Rebuild or configure it in the new environment, test both success and failure, and reconcile downstream outputs.

### Which integrations should be rebuilt vs replaced?

Rebuild integrations that remain strategically important and can be supported safely; replace those tied to obsolete contracts, fragile custom code or capabilities the new platform already provides. Record the owner and migration path for each.

### How should ERP integrations be tested?

Test product, customer, price, inventory, order, cancellation and refund flows in both directions as applicable. Verify identifiers, sequencing, retries, and reconciliation with the ERP owner.

### How should CRM integrations be tested?

Test customer creation, updates, consent, segmentation, and duplicate handling with known identities. Confirm field ownership, so the store and CRM do not overwrite each other unexpectedly.

### How should shipping integrations be tested?

Test rates, labels, tracking, cancellation, service errors, and delayed carrier responses. Use representative packages, origins and destinations and confirm safe retry behavior.

### How should tax integrations be tested?

Test taxable and exempt customers, product categories, locations, prices, discounts, shipping and refunds. Compare expected and actual calculations with the tax owner or provider.

### How should marketing integrations be tested?

Test audience updates, product feeds, campaigns, conversions, consent and deduplication. Confirm failed or delayed events can be found and replayed safely where supported.

### How do I know whether an integration is ready for launch?

An integration is ready when critical scenarios and failures pass, credentials and monitoring are production-ready, outputs reconcile and an accountable business owner approves the evidence.

### A quick store check

Pick one critical integration and trace a successful event, a retry and a permanent failure through logs and destination records.

## Frequently asked questions

### Who signs off an integration?

The technical owner proves the contract and monitoring; the business owner confirms the resulting workflow and data.

### Should failed events be replayed automatically?

Only when replay is supported and idempotent so it cannot duplicate payments, orders or inventory actions.
