* [ ] [Using the Refunds API, can you initiate a refund request from the admin portal of your commerce system?](#initiate-refunds-in-your-admin-portal)
* [ ] [Using the Refunds API, can you display details about previous refund requests from the admin portal of your commerce system](#display-refund-information-in-your-admin-portal)?

## Integration standards

These integration standards relate to reversals:

### Initiate refunds in your admin portal

You should build a mechanism for submitting refund requests in your commerce system's admin portal. When you build this feature, you should also ensure you can capture and display any [failure reasons](/digital-river-api/order-management/returns-and-refunds-1/refunds.md#dealing-with-refund-failures) returned by a call to the [Refunds API](https://docs.digitalriver.com/digital-river-api-reference/2021-12-13/refunds).

### Display refund information in your admin portal

In your commerce system's admin portal, you should build a mechanism that [searches for previously requested refunds](https://docs.digitalriver.com/digital-river-api-reference/2021-12-13/refunds#refunds) and displays that information. This information should be available per order using the [Orders resource](https://docs.digitalriver.com/digital-river-api-reference/2021-12-13/orders) and per refund using the [Refunds resource](https://docs.digitalriver.com/digital-river-api-reference/2021-12-13/refunds).
