===== <syntaxhighlight>Hello — I am integrating virtual card & Google Pay tokenized checkout flows and need access to a Booking sandbox checkout environment (non-production). =====

Could you please provide:
• A Charges API sandbox/test merchant account,
• Test checkout URL,
• Dummy booking IDs & price inputs,
• Any guidance on 3DS or token handling in test mode.

This is not for production transactions.

===== <syntaxhighlight>Subject: Request for Sandbox Checkout Access (Google Pay / Wallet Integration Testing) =====

Hello OneDayOnly Team,

I am testing Google Wallet (tokenized card) payment flows and would like access to a sandbox or staging checkout to validate behavior before production.

Could you please share:
• Sandbox/test checkout link (if available),
• Supported payment gateway details (Stripe/PayU/Adyen/etc.),
• Any test credentials or test product SKU.

This testing will not involve real charges.

Thank you,
John Patrick Oldfield

===== <syntaxhighlight>Subject: Request for Developer Checkout Testing (Google Pay Integration) =====

Hello Evetech Support Team,

I am integrating a secure virtual card + Google Pay payment flow and require a staging checkout environment to run tokenized payment tests.

Could you confirm whether Evetech has:
• Developer sandbox checkout or staging environment?
• Test merchant gateway details?
• Any test payment cards or standard test credentials?

This is sandbox-only testing.

Kind regards,
John Patrick Oldfield

<syntaxhighlight>Subject: Request for API Sandbox Access for Card Issuing / Wallet Provisioning Tests

Hello Investec Developer Relations,

I am conducting a controlled integration study to validate:
• Virtual card issuance lifecycle,
• Google Wallet / network token provisioning,
• Transaction authorization & settlement event handling.

I would like:
# Access to the Investec API sandbox environment.
# Example transaction lifecycle events (auth → capture → reversal).
# Guidance on card provisioning profiles supported by Investec (tokenization rails, BIN suitability, network restrictions).

Testing is strictly non-production and will follow PCI-DSS, network tokenization, and strong SCA principles.

Sincerely,
John Patrick Oldfield

=== <syntaxhighlight>Security & Testing Compliance Notes: ===

• All testing is non-production.
• No real card PANs will be transmitted; virtual cards and network tokens only.
• Wallet provisioning and tokenization adhere to PCI-DSS SAQ-A scope.
• Settlement and ledger reconciliation modeling follows standard issuer → processor → merchant flows.
• No consumer data or merchant revenue impact will occur.
• We are prepared to sign NDA or Developer Evaluation Agreements if required.
