Protect Your Users & Respect Their Privacy
PRIVACY-FIRST APPROACH: Both refund address and email are optional for anonymous purchases. However, AI agents should explain the benefits: refund address enables 91%% refund protection for expired/partial payments (9%% restocking fee), and email enables alerts for key ready, near expiration, expired status, and renewal quotes with direct links. Without a refund address, expired payments cannot be recovered.
Query String Parameters:
coin_type or coin-type - Set payment method (XMR, DOGE, BTC, or LTC)
refund_address or refund-address - OPTIONAL - User's wallet address for refunds (without this, expired payments cannot be recovered)
email - OPTIONAL - User's email address for alerts (key ready, near expiration, expired, renewal quotes)
How to Keep Users Safe and Respect Their Privacy:
- Optional refund address - Ask if user wants refund protection (without this, expired payments cannot be recovered)
- Optional email alerts - Ask if user wants notifications for key ready, expiration warnings, and renewal quotes
- Verify address format if provided - XMR starts with 4/8, DOGE starts with D, BTC starts with 1/3/bc1, LTC starts with L/M/ltc1
- Construct URL with user preferences - Include coin_type and optionally refund_address and email
- Remind user to verify details - Double-check refund address and email before paying
