## "The payment could not be started. Please try another method."

The gateway refused to open a payment. Almost always the **keys**:

- The keys are wrong, incomplete, or have a space at the start or end. Paste them again.
- **Environment** does not match the keys: test keys with **Live**, or live keys with **Test / sandbox**.
- The gateway has not activated your live account yet, or has suspended it — check your gateway dashboard.
- **Paytm:** **Website** is still `WEBSTAGING` with live keys.
- **PayU:** the salt is not the **v1** salt matching the key.
- **CCAvenue:** the working key was generated for a different domain, or regenerated since you saved it.

Switch the method to **Admins only**, fix the keys, and test again.

## "That payment method is no longer available." / "That payment method is not available."

The method was switched off or removed while the customer was checking out, or its rules no longer allow this order. Ask them to choose another method.

## Paid, but the order stays Pending

The customer paid, but your store never heard about it — usually because they closed the window before returning to your store.

- **Add the webhook** in your gateway's dashboard (Razorpay, PhonePe, Cashfree, Stripe, PayPal): copy the **Webhook / callback URL** from the method in your admin, and enter the matching secret. See the guide for your gateway.
- Check the payment in the gateway's dashboard. If it is captured, set the order to **Confirmed** by hand; note that its *payment status* stays Pending.

## A "Test" badge on checkout

The method's **Environment** is **Test / sandbox**. Customers paying with real cards will fail. Switch to **Live** with live keys.

## Customers see a gateway error page

The message on the gateway's page is the gateway's own — *card declined*, *bank server down*, *transaction limit exceeded*. These are between the customer and their bank; suggest another card, UPI, or another method.

## "Fill in every required credential before switching this on."

Some required keys are empty. Each gateway's required fields are marked with *****.

## Refund failed

*Gateway refund failed; recorded as a manual refund for you to settle.* — the gateway refused the refund (for example, too long after the payment, or insufficient balance). Pay the customer yourself and record the UTR. See [Refunds and store credit](https://www.nijeesweb.com/docs/ecommerce/orders/refunds-and-store-credit).
