--- title: One-time payment scenarios url: amazon-pay-checkout/one-time-payment-scenarios.html --- You can authorize and capture payment at time of checkout or after checkout is complete. Below are details for different one-time payment scenarios. * TOC {:toc} {::options toc_levels="3" /} *** ### Capturing full order amount at checkout Capture the full order amount at checkout by setting Checkout Session `paymentDetails.chargeAmount` to the full order amount and `paymentDetails.paymentIntent` to AuthorizeWithCapture. Do not capture payment at checkout for pre-orders, backordered items, or if the expected delivery date is in the future; you should only request payment authorization at checkout or authorize and capture payment after checkout once you’re ready to fulfill the order. ### Authorizing full order amount at checkout Authorize the full order amount at checkout by setting Checkout Session `paymentDetails.chargeAmount` to the full order amount and `paymentDetails.paymentIntent` to Authorize. Call Capture Charge with the `chargeId` returned at the end of checkout to capture payment. If you do not capture the full order amount or if the Charge expired after 30 days, you can call Create Charge up to 25 times using `chargePermissionId` as long as the total amount captured does not exceed the Charge Permission `amountLimit`. Note that the Charge Permission will expire after 180 days. ### Partial authorization or capture at checkout Authorize or capture for partial order amount at checkout by setting Checkout Session `paymentDetails.chargeAmount` to the amount you want to process during checkout and `paymentDetails.totalOrderAmount` to the full order amount. Specify whether you want to authorize or capture the `chargeAmount` when the order is placed by setting `paymentDetails.paymentIntent` to Authorize or AuthorizeWithCapture. If you use the Authorize `paymentIntent`, call Capture Charge with the `chargeId` returned at the end of checkout to capture payment; you can also call Create Charge up to 25 times using `chargePermissionId` as long as the total amount captured does not exceed the Charge Permission `amountLimit`. ### Authorization and capture after checkout Authorize and capture payment after checkout by setting Checkout Session `paymentDetails.chargeAmount` to the full order amount and `paymentDetails.paymentIntent` to Confirm. Call Create Charge up to 25 times with the `chargePermissionId` returned at the end of checkout to authorize and capture payment. Note that the Charge Permission will expire after 180 days.
