Symptom
A gateway migration can break checkout, callbacks, saved payment methods, refunds, subscriptions, customer messaging, or reconciliation if only the purchase path is tested.
For: WooCommerce agencies, developers, and store owners changing providers, merchant accounts, gateway plugins, or payment configurations.
Diagnosis
What to check before changing the site
Old Gateway Dependencies
Do not remove old provider access too quickly. Refunds, disputes, captures, reconciliation, and subscriptions may still need it.
Webhook Cleanup
Old and new webhooks should be mapped deliberately. Stale endpoints are a common source of pending orders and duplicate confusion.
Rollback And Freeze
A migration needs a freeze window, rollback owner, and clear decision point for disabling or re-enabling gateways.

Diagnosis
Symptoms, causes, checks, and fixes
Symptoms
- The store is switching providers, merchant accounts, gateway plugins, payment methods, or checkout implementations.
- Old and new gateway settings, webhooks, credentials, and return URLs coexist during migration.
- Refunds, saved methods, subscriptions, or pending orders may still depend on the old gateway.
Most Common Causes
- Gateway migrations affect more than checkout: refunds, captures, webhooks, subscriptions, saved payment methods, disputes, reports, and customer emails can all change.
- Old webhooks and return URLs often remain pointed at staging, a previous domain, or an inactive provider account.
- Rollback can be difficult if credentials, plugin versions, or provider access are removed too early.
How To Confirm The Cause
- Inventory old and new gateway plugins, credentials, modes, webhook endpoints, return URLs, supported currencies, saved methods, subscriptions, refunds, and provider dashboards.
- List open orders, pending payments, disputes, subscriptions, and refund windows that still depend on the old gateway.
- Test checkout, failure, pending, refund or void, email, webhook, and reporting behavior on staging before production changes.
Fixes
- Stage the migration with a freeze window, rollback owner, provider access, and customer-support note.
- Keep old gateway access long enough to handle refunds, disputes, subscription renewals, or reconciliation needs.
- Update webhooks, credentials, return URLs, checkout messaging, and internal support scripts together.
How To Verify The Fix
- Complete controlled production verification according to policy and confirm order status, provider record, email, webhook, and refund path.
- Monitor failed, pending, duplicate, refund, and subscription patterns after migration.
- Close migration only after old-gateway dependencies and rollback requirements are documented.
When To Contact Support
Escalate when subscriptions, saved cards, disputes, banking, settlement, legal compliance, or provider account ownership is involved.
