Welcome to the Loop Returns API reference! Below you'll find a summary of our current API and webhook capabilities. Click on any of the links to learn more.

Webhooks

Webhooks are HTTP callbacks processed and sent by Loop to a pre-defined URL. They allow your application to receive information from Loop without having to reach out to Loop via an API call.

Returns API

The Returns API is by far the most common API used by our brands and partners. Use the Returns API to generate RMAs and ASN reports, as well as process returns when they've been received.

Listings API

The Listings API is used to maintain a brand's blocklists and allowlists. Blocklists are used to prevent returns based on certain criteria, while allowlists are used to make certain exceptions to blocklist entries.

Orders API

The Orders API, formerly known as the Deeplink API, allows you to link directly to a customer's order in Loop so they can initiate a new return, without requiring them to submit their order details.

Cart API

The Cart API is specifically used for brands using our Shop Now On Store functionality. This feature enables customers to exchange a returned product for another product directly from your online store.
