Subject: Request for Developer Sandbox / Test Merchant Access — Integration Testing with Virtual Card

<syntaxhighlight>Hello [Developer Support / Integrations Team],

My name is John Patrick Oldfield, and I am integrating a payment validation and provisioning solution for testing with [Your Company / Project]. I require access to your developer sandbox environment and a merchant test checkout to validate card provisioning and payment flows.

Specifically, I request:
# Sandbox / staging URL for your checkout flow (or credentials for your developer sandbox).
# Test merchant account or test API keys for your payment gateway (if you use a gateway like Stripe/Adyen/Braintree) allowing payment processing in sandbox.
# A sample test cart endpoint or a reproducible test checkout (product ID, prices, and sample customer data) so I can execute end-to-end tests.
# Any developer documentation describing the exact test card numbers accepted and any special headers or test credentials.
# If you support wallet provisioning tests, instructions for adding virtual/test cards to Google Wallet for use in the sandbox.

Use case summary:
* We plan to provision an Issuing virtual card and test tokenized payments via Google Wallet/Google Pay on your checkout pages.
* This testing is strictly sandbox-only and will not be used for fraud or production charges.

Please let me know any NDAs or paperwork required to enable this access. I can provide technical contact details and scheduling for test sessions.

Thank you,
John Patrick Oldfield

If you prefer, I can customize this for each specific retailer (Booking / Takealot / Travelstart / Evetech) and highlight the exact API names or gateway those merchants typically use — provide the retailer-specific dev contact emails or support URLs and I’ll stitch it into the letters.
