The integration of Droppas return service relies on integrating the Droppa public APIs. These APIs consist of two parts, the GraphQL API
and the webhooks.
The GQL API will mainly be used for passing data to Droppa that is needed to handle returns. This contains information like Orders, Products and Customers. If the return interface is build by the merchant themselves also the Return is added through the GQL API.
The webhooks are used to notify the merchant of events from inside of Droppa. These events are Return Created and tracking events.
