Zoho Payments for WHMCS

Accept payments natively in WHMCS via Zoho Payments' embedded checkout widget. Customers pay seamlessly on your invoice page without external redirects.

Key Features

• Embedded On-Page Checkout Widget: Customers complete their payment directly inside your WHMCS portal using credit/debit cards, net banking, UPI, and local payment options.
• Multi-Region Data Centre Support: Fully supports both India (.in) and US (.com) Zoho data centres with region-specific OAuth2 endpoints.
• OAuth 2.0 with Automatic Token Refresh: Secure token-based API authentication with automatic background refresh — no manual token re-entry needed.
• HMAC-SHA256 Signed Webhooks: Webhook callbacks are cryptographically verified using HMAC signatures to automate invoice updates safely.
• Direct Server-Side Verification: In addition to webhooks, every on-page transaction is immediately verified against Zoho's server-side Payment APIs before invoice marking.
• Sandbox & Live Environments: Easily switch between Zoho Payments Test/Sandbox and Live production modes.
