  Move Zoho Payments for WHMCS from test mode to live — verify your setup, run a
  real test payment, then switch Test Mode off with confidence.

# Going live

The final check before accepting real money: confirm the setup, prove the full flow in test mode, then flip **Test Mode** to live.

## 1. Test in test mode

Keep **Test Mode** set to **Yes** and run a complete payment.

1. Open an invoice in the client area → **Pay Now**.
2. Complete the payment inside the [Zoho widget](/zoho-payments-whmcs/features/widget-checkout).
3. Confirm the invoice reaches **Paid**, with transaction details and fee recorded.
4. If you use [Payment Links](/zoho-payments-whmcs/features/webhooks-and-payment-links), test one and confirm the webhook marks the invoice Paid.

::: tip Watch the Gateway Log
Keep **Utilities → Logs → Gateway Log** open while you test — the fastest way to see whether verification and webhooks succeed.

## 2. Go-live checklist

* \[ ] **License Key** entered and active — payments are blocked while it's inactive ([Licensing](/zoho-payments-whmcs/licensing))
* \[ ] **Data Center** matches your Zoho account (`IN` or `US`)
* \[ ] **Client ID**, **Client Secret**, and a valid **Refresh Token** in place
* \[ ] **Account ID** and **Widget API Key** entered — the widget loads
* \[ ] **Webhook** added in Zoho for **Payment completed** and **Payment Link paid**, with **Webhook Secret** matching the config
* \[ ] Valid **SSL certificate** so the webhook endpoint is reachable
* \[ ] A **test-mode payment** completed and reached **Paid**, fee recorded

::: warning Use live credentials for production
If your Zoho account uses separate credentials for test and live environments, update **Client ID**, **Client Secret**, **Refresh Token**, and **Widget API Key** before going live.
:::

## 3. Switch to live

**Setup → Payment Gateways → Zoho Payments** → set **Test Mode** to **No** → **Save Changes**.

## 4. Verify live

Process a small live payment to confirm end-to-end processing. Verify the invoice marks **Paid** and processing fees log accurately. Monitor **Utilities → Logs → Gateway Log** during early live transactions.

::: tip If something looks off
