## CI

[![Tests](https://github.com/bizon/mws-sdk/actions/workflows/tests.yml/badge.svg)](https://github.com/bizon/mws-sdk/actions/workflows/tests.yml)
[![Release](https://github.com/bizon/mws-sdk/actions/workflows/release.yml/badge.svg)](https://github.com/bizon/mws-sdk/actions/workflows/release.yml)

## Getting started

```bash
npm install --save @bizon/mws-sdk
```

## Usage

```js
const MWSClient = require('@bizon/mws-sdk')

const client = new MWSClient({
  accessKeyId: '', // defaults to process.env.MWS_ACCESS_KEY_ID
  secretAccessKey: '', // defaults to process.env.MWS_SECRET_ACCESS_KEY
  sellerId: '',
  mwsToken: '',
  mwsRegion: ''
})
```

### Region and Marketplaces

[The MWS documentation](https://github.com/bizon/mws-api-doc/blob/master/doc/en_FR/dev_guide/DG_Endpoints.md) defines a list of regions and marketplaces available in each region.

The marketplaces in a region do not all share a common API endpoint, so this library defines a new concept of *MWS region*, based on the API endpoint. Here’s the list of the available MWS regions:

**Generic MWS regions:**

Region | API Endpoint | Name
-------|--------------|-----
na | mws.amazonservices.com | North America
eu | mws-eu.amazonservices.com | Europe
fe | mws-fe.amazonservices.com | Far East

**Country specific MWS regions:**

Region | API Endpoint | Name
-------|--------------|-----
ca | mws.amazonservices.ca | Canada
mx | mws.amazonservices.com.mx | Mexico
ae | mws.amazonservices.ae | United Arab Emirates
in | mws.amazonservices.in | India
jp | mws.amazonservices.jp | Japan
au | mws.amazonservices.com.au | Australia

This library also allows to specify a list of marketplaces (either 2 letter country codes, marketplace IDs or domains) so you can restrict API calls to your marketplace participations:

```js
const client = new MWSClient({
  accessKeyId: '',
  secretAccessKey: '',
  sellerId: '',
  mwsToken: '',
  marketplaces: [
    'A1F83G8C2ARO7P', // UK
    'fr',
    'Amazon.it'
  ]
})
```

Keep in mind that the specified marketplaces will have to be in the same MWS region, otherwise an error will be thrown.

## Pagination

The MWS API defines multiple API calls for pagination. They have been abstracted in this SDK. Whenever there are more retrievable results, a `nextToken` property will be available in the operation’s result. The `nextToken` can then be used as an option of that same operation to fetch an additional page.

```js
let nextToken

do {
  const result = await client.orders.listOrders({
    nextToken, // If nextToken is truthy, all the other options are ignored.
    lastUpdatedAfter: new Date(2020, 0, 1)
  })

nextToken = result.nextToken
} while (nextToken)
```

## Error handling

Whenever the MWS API returns a non-OK HTTP status, a `MWSError` will be thrown. Use `error.body` to inspect the contents of the error, and `error.response` to access the raw HTTP response.

```js
const {MWSError} = require('@bizon/mws-sdk')

try {
  const result = await client.products.getLowestPricedOffersForSku({
    marketplaceId: 'A1F83G8C2ARO7P',
    sellerSku: 'some-sku',
    itemCondition: 'new'
  })
} catch (error) {
  if (error instanceof MWSError) {
    console.log(error.sellerId)
    console.log(error.marketplaces)
    console.log(error.body) // This will contain the parsed XML body
    console.log(error.response.statusCode)
  }
}
```
