This tutorial covers how to create, retrieve, and update customer records, which are needed for payment processing and storing payment methods.
Create Customer
Use POST /customers to create a customer record. See the Onboard a Merchant tutorial for a concrete example.
Retrieve & Update
Use existing GET /customers/{customerId} and PATCH /customers/{customerId} endpoints to retrieve and update customer information.
Best Practices
- Attach metadata to customers for easier reconciliation (order IDs, source, etc.).
- Use webhooks to track updates to saved payment methods or customer changes.
