# Complete a Checkout

`POST /v1/checkouts/{order_reference_id}/complete`

Initiate order payment capture if `merchant_completes` was `true` at Create Checkout.
An example use-case is if users need to return to the merchant's site before finalizing the purchase with Sezzle.
Submit the Complete Checkout request within 30 minutes after the user is redirected to the merchant's site. Failure to do so results in Sezzle canceling the checkout.
The default expiration period for new orders can be extended up to 7 days via the Merchant Dashboard.
