Why Webhook Migration Is Critical

Webhooks are the nervous system of your payment infrastructure. Getting this wrong can break critical business processes.

What Breaks Without Proper Migration

  • Subscription renewals not processed
  • Failed payment notifications missing
  • Customer account updates not synced
  • Accounting integration failures

Proper Migration Ensures

  • Uninterrupted business operations
  • Seamless integration continuity
  • Real-time event processing
  • Customer experience preservation

Pre-Migration Assessment

Inventory Your Current Webhooks

Before migrating, document all existing webhook endpoints:

  • Endpoint URLs: List all webhook URLs configured in your current Stripe account
  • Event Types: Document which events each endpoint handles
  • Connected Systems: Identify which applications or services consume each webhook
  • Critical vs. Non-Critical: Classify webhooks by business impact

Access Your Webhook Settings

In your Stripe Dashboard, go to Developers → Webhooks to see all configured endpoints and their event subscriptions.

Common Webhook Event Types

Critical Business Events

  • • invoice.payment_succeeded
  • • invoice.payment_failed
  • • customer.subscription.updated
  • • customer.subscription.deleted
  • • payment_intent.succeeded

Customer Management

  • • customer.created
  • • customer.updated
  • • customer.deleted
  • • payment_method.attached
  • • payment_method.detached

Webhook Migration Strategy

Option 1: Parallel Processing (Recommended)

Run both old and new webhooks simultaneously during migration period

Advantages

  • • Zero downtime for webhook processing
  • • Easy rollback if issues occur
  • • Data validation through comparison
  • • Gradual transition capability

Considerations

  • • Duplicate event handling logic needed
  • • Higher resource usage temporarily
  • • More complex monitoring required

Option 2: Sequential Migration

Migrate webhooks one by one with careful timing

Advantages

  • • Simpler implementation
  • • No duplicate processing logic
  • • Easier to debug issues
  • • Lower resource requirements

Risks

  • • Potential event loss during switch
  • • Harder to rollback quickly
  • • Requires precise timing

Implementation Steps

1

Update Application Code

Modify your webhook handlers to work with the new Stripe account

Code Changes Required:

  • • Update webhook signing secret verification
  • • Handle account ID differences in event data
  • • Add duplicate detection if using parallel processing
  • • Update any hardcoded account references
2

Configure New Webhooks

Set up webhook endpoints in your destination Stripe account

Configuration Steps:

  • • Create webhook endpoints with identical event subscriptions
  • • Use same URLs or create new staging endpoints
  • • Configure appropriate API versions
  • • Set up monitoring and logging
3

Test Webhook Delivery

Verify webhooks work correctly before going live

Testing Checklist:

  • • Test with Stripe CLI webhook forwarding
  • • Create test events in destination account
  • • Verify signature validation works
  • • Check that all expected events are received
4

Execute Migration

Switch webhook processing to the new account

Migration Steps:

  • • Enable new webhooks during low-traffic period
  • • Monitor both old and new webhook processing
  • • Gradually shift traffic if using parallel approach
  • • Disable old webhooks once confident in new setup

Common Issues & Solutions

Webhook Signature Verification Failures

Issue: Webhooks fail signature verification with new account

Solution: Update your webhook signing secret to the one from your new Stripe account. Each account has a unique signing secret.

Event Data Mismatches

Issue: Webhook handlers expect different object IDs or structures

Solution: Update handlers to work with new object IDs. Consider using metadata or external references for data mapping during transition.

Duplicate Event Processing

Issue: Events processed twice when using parallel webhook approach

Solution: Implement idempotency keys or event deduplication logic based on event IDs and account sources.

Missing Historical Events

Issue: Need to replay events from migration period

Solution: Use Stripe's Events API to retrieve and replay missed events. Consider queuing mechanisms for reliable processing.

Webhook Migration Best Practices

Before Migration

  • Document all webhook dependencies
  • Test webhook handlers in staging
  • Set up comprehensive monitoring
  • Prepare rollback procedures

During Migration

  • Monitor webhook delivery rates
  • Check for processing errors
  • Validate data consistency
  • Maintain team communication
