USDPAY for WHMCS lets hosting providers, VPN services, SaaS businesses, AI tools, and other online services accept USDT payments directly from WHMCS.

After a customer pays, USDPAY verifies the blockchain transaction and sends a signed webhook to WHMCS. The corresponding invoice is automatically marked as paid, allowing WHMCS to continue with its standard provisioning and service activation workflow.
