Why Are CS-Cart Orders Stuck in Pending After Payment?

Customers may see a successful payment at the provider while a CS-Cart order remains pending. The payment confirmation may be delayed, the callback URL may be blocked, a signature may fail validation, or the provider may send a different status than the integration expects. Manually marking orders paid can create reconciliation problems if the payment was later declined or reversed.

Match one order across systems

Use the order number, provider transaction reference, and timestamps to compare CS-Cart order history with the gateway's event log. Check the callback response code, signing secret, allowed IP rules, and any recent add-on or server changes. Keep payment card details out of logs and screenshots.

Handle uncertain payments safely

• Check whether the provider captured, authorized, or only attempted the payment.
• Review duplicate callbacks and idempotency behavior before retrying.
• Use the provider's reconciliation view to identify settled transactions.
• Document affected order IDs and agree on a controlled correction process.
• Test callbacks in a sandbox after correcting the integration.

Prevent repeat incidents

Monitor callback failures and reconcile pending orders on a schedule. Keep the gateway integration and CS-Cart add-on versions documented so changes can be traced.
