## Overview

After creating a `charge`, you can manage it through various states and integrate each of these actions into your order management system where you fulfill orders and/or process payments, refunds, and cancelations.

## Read charge

With the `Read charge` API, you can use the `charge_id` to retrieve all checkout data and the charge status associated with a specific charge. Reading charge information is useful for updating your records or order management system with the current state of a charge before performing any actions on it. It can also keep your system in sync with Affirm if your staff is manually managing loans in the merchant dashboard.

You can read single or multiple charges. Note that if you don't specify a `charge_id`, the response includes a list of charges. You can define how the results are paginated using the `limit`, `before`, and `after` query parameters.

## Void

To cancel or delete an authorized charge, you can use the `charge_id` to void it. For example, when a user decides to cancel their order before it's fulfilled. Voiding an authorized charge does the following:

  • Permanently cancels a loan

  • Notifies the user that the transaction was canceled

## Refund

Refund a charge based on the original purchase, similar to refunding a credit card transaction. Affirm automatically calculates all interest and fees corresponding to the refunded amount. You can also optionally refund part of a transaction by specifying an amount. For partial refunds, you can apply any amount of refunds so long as there is a positive balance on the loan.

Once a loan has been fully refunded, it can’t be reinstated. You can refund the customer using the Refund API or the [Merchant Portal](🔗).

## Update

Use the `Update` API to update a charge with new fulfillment or order information, such as `shipping_confirmation`, `shipping_carrier`, or `order_id`. Settlement reports associate your internal order IDs with specific Affirm charges.
