What should you prepare for PayPal?

Gather merchant, website and order information, then prepare test cases for payments, refunds and reconciliation.

Write down who receives the payment, how a customer checks out and when an order is considered paid. This helps identify gaps in checkout, support and operations before the integration begins.

Gather merchant and website information

• Merchant location, target markets, product category and expected currencies.
• Public website, product pages, checkout entry and customer contact options.
• Delivery, cancellation, refund and support information customers can read.

Confirm the payment capabilities available to the actual merchant and markets before setting the integration scope.

Map payment status to orders

Keep an order number and transaction identifier that can be matched. Define what customers and staff see when a payment succeeds, fails, is cancelled or remains pending.

Build a pre-launch test checklist

1. Start from a product page and verify the checkout currency, shipping and total.
2. Test success, failure and cancellation and check the status shown on the website.
3. Reconcile refunds against orders and document how support can find exceptions.
