Overview
Migrate from Commerce Charge API to Payment Link API for improved reliability, simplified integration, and modern authentication. This guide covers the key changes and provides code examples to help you update your integration.Migration summary
Migration summary
1
Update authentication
Switch from API key to JWT Bearer tokens
2
Change base URL
From
api.commerce.coinbase.com to business.coinbase.com/api/v13
Update request/response handling
New field names and flattened structure
4
Implement status monitoring
No webhooks yet, use polling or blockchain monitoring
5
Test thoroughly
New ID formats and status values require updates to your logic
Key differences
| Component | Charge API (Commerce) | Payment Link API |
|---|---|---|
| Base URL | https://api.commerce.coinbase.com | https://business.coinbase.com/api/v1 |
| Authentication | X-CC-Api-Key header | Bearer token with CDP API key |
| Primary resource | Charge | Payment Link |
| ID format | UUID | 24-character hexadecimal |
| Payment URL field | hosted_url | url |
Payment Link API requires CDP API key authentication.
Status and field mappings
| Feature | Charge API | Payment Link API |
|---|---|---|
| Status values | NEW, SIGNED, PENDING, COMPLETED, EXPIRED, FAILED | ACTIVE, DEACTIVATED, EXPIRED, COMPLETED |
| Amount structure | local_price.amount and local_price.currency | amount and currency (flat structure) |
| Network specification | Auto-selected | Explicit network field |
| Redirect URLs | redirect_url, cancel_url | successRedirectUrl, failRedirectUrl |
Migration checklist
1. Update authentication
- Create CDP API keys
- Implement JWT Bearer token generation
- Update API key storage and rotation procedures
- Test authentication with Payment Link API
2. Update API integration
- Update base URL to
https://business.coinbase.com/api/v1 - Modify request bodies to match new schema
- Update response parsing to handle new field names
- Implement idempotency key generation for create requests
3. Handle status changes
- Map Charge statuses to Payment Link statuses in your system
- Update order fulfillment logic for new status values
- Implement payment monitoring (polling or blockchain monitoring)
- Update customer-facing status messages
4. Update payment flows
- Use
urlfield instead ofhosted_urlfor payment pages - Update redirect URL parameters
- Test full payment flow end-to-end
- Verify metadata is correctly passed through
5. Handle pagination
- Update list operations to use
pageSizeandpageToken - Implement
nextPageTokenhandling for multiple pages - Test pagination with large datasets
6. Test and validate
- Test with minimal amounts
- Verify amount calculations (ensure proper decimal handling)
- Test expired payment link scenarios
- Test deactivation flow
- Verify metadata preservation
- Test redirect URLs
7. Monitor and observe
- Set up monitoring for API errors
- Track payment success rates
- Monitor payment link expiration rates
- Set up alerts for failed payments
