Order statuses and payment flow

1. The customer confirms the order. The order is created in the status COMGATE – waiting for payment.
2. As you set it up, the module redirects the customer to the Comgate gateway, or shows the payment page with the inline gateway or the Checkout SDK. See Gateway display methods.
3. The customer pays. The module always verifies the payment result directly with Comgate, in three ways:
   • when the customer returns from the gateway,
   • from a PUSH notification from Comgate,
   • by cron, if the notification does not arrive.
4. A paid order moves to the chosen status and the transaction number is stored with the order’s payment.

The payment status is never taken from the browser; it is always verified in Comgate.

On installation the module creates four order statuses. They do not send PrestaShop e-mails and do not create a credit note.

Status	When
COMGATE – waiting for payment	The order was created and waits to be paid.
COMGATE – payment interrupted	The payment was cancelled or expired.
COMGATE – payment authorization confirmed	With pre-authorization the amount is blocked on the card.
COMGATE – refund	The full amount was refunded.

You can choose the statuses after payment and after a refund in the Order statuses panel.

• A paid payment changes the order status if the order has not been paid yet.
• An authorized and a cancelled payment change the status only when the payment is the latest one and the order is still waiting (the status waiting for payment or payment interrupted). A status you set in the order yourself stays.
• Repeated notifications change nothing.
• After a payment is cancelled, the order is not cancelled (by default), so the customer can pay it again. You can change this in the settings.

• A pending payment of the same display (within 30 minutes) is reused by the module. Another payment is cancelled first.
• Cron checks pending payments older than 5 minutes and younger than 8 days.

Without a valid license, payment is not offered at checkout. Notifications from Comgate are then not accepted (Comgate retries them) and cron catches them up after a license is uploaded, so payments are not lost.

Payments and refunds are stored in their own tables in the database. Uninstalling does not delete them.
