 ## Endpoints
 
 All endpoint URIs are relative to the `SPAPI_ENDPOINT` value you specify in your `.env` file (the default is https://sellingpartnerapi-na.amazon.com). For instance, the `SellersApi::getMarketplaceParticipations()` endpoint, `/sellers/v1/marketplaceParticipations`, is expanded to `https://sellingpartnerapi-na.amazon.com/sellers/v1/marketplaceParticipations`.

 The [`docs/Api/`](https://github.com/jlevers/selling-partner-api/tree/main/docs/Api) directory contains the documentation for interacting each distinct section of the Selling Partner API. Those sections are referred to as **APIs** throughout the documentation---you can think of the Selling Partner API as having many sub-APIs, where each sub-API has a number of endpoints that provide closely related functionality.
 
 Endpoint methods that perform `POST`, `PUT`, and `DELETE` requests typically take some model as a parameter, and nearly all endpoint methods return a model with result information. For instance, [`ShippingApi::createShipment()`](https://github.com/jlevers/selling-partner-api/blob/main/docs/Api/ShippingApi.md#createShipment) takes an instance of the [`CreateShipmentRequest`](https://github.com/jlevers/selling-partner-api/blob/main/docs/Model/Shipping/CreateShipmentRequest.md) model as its only argument, and returns an instance of the [`CreateShipmentResponse`](https://github.com/jlevers/selling-partner-api/blob/main/docs/Model/Shipping/CreateShipmentResponse.md) model.
