# Authorize & Capture

Merchants integrating Sezzle into their eCommerce platform can choose between two payment settings: `Authorize Only` or `Authorize and Capture`. This page provides a detailed explanation of the differences between these options to help you select the best setting for your needs.

### **Authorize Only**

* Payment will only be automatically authorized, not captured, after a successful checkout
* In the History section of order details, the `Captured` field displays 0, and `Not Captured` displays the order amount
* If `Authorize Only` is set, you must capture the order amount manually before the auth is expired in order to mark the payment as paid

### **Authorize and Capture**

* Payment is captured automatically after a successful checkout.
* In the `History`section of order details, the `Captured` field displays the order amount, and `Not Captured` displays 0

### Notes

* The default authorization expiration is 30 minutes for all merchants except Shopify, whose default is 7 days
  * You can extend this up to a maximum of 7 days
* Once the authorization expires, capturing is denied, and any uncaptured amount is released
  * If the order total is not captured before expiration, the order is deleted
* Payment is considered paid only when the amount is captured
  * If the order amount shows `Not Captured` and the `Captured` value in the `History` section of the Merchant Dashboard is 0, the order amount has not been captured
* If the amount remains uncaptured before the authorization expires, the order will be deleted

### How to Change Authorization Expiration in Merchant Dashboard

1. Log in to your Merchant Dashboard account
2. Go to the `Settings` > `Payment Captures` > `Authorization Expiration Period` and click `update`
3. Set the value for days, hours, and minutes and click `confirm`
