## mws-client

Creates a new client to communicate with MWS API

**Returns**: [`MWS`] - MWS client

| Param | Type | Description |
| --- | --- | --- |
| opts | [`Options`] | Options to be passed to instanciate a new client |

**Example**
```js
const MWS = require('mws-client')({
AWSAccessKeyId: process.env.YOUR_AWS_ACCESS_KEY,
SellerId: process.env.YOUR_SELLER_ID,
MWSAuthToken: process.env.YOUR_MWS_AUTH_TOKEN
})
```

## Section

A section of MWS API. **Note: all sections and associated endpoints are generated automatically when instanciating a new client**

**Kind**: global class

### Section.endpoint(opts)

Send a request to the given endpoint

**Kind**: static method of [`Section`]
**Returns**: [`MWSResponse`] - Response received from MWS API

| Param | Type | Description |
| --- | --- | --- |
| opts | `Object` | Parameters for the API call. See [here] for details regarding parameters for every endpoints. **Note: list parameters are not supporting `Array` type yet. You will have to build them in the same way as they appear in the query string of the signed request to MWS API (i.e. `param.1=foo&param.2=bar`)** |

**Example**
```js
// retrieves inventory from given date for the German marketplace
const list = await MWS.fulfillmentInventory.listInventorySupply({
QueryStartDateTime: new Date(d).toISOString(),
ResponseGroup: 'Basic',
_marketplace: 'DE'
})

// retrieve status of the fullfillmentInventory API for the German marketplace
const status = await MWS.fulfillmentInventory.getServiceStatus({ _marketplace: 'DE' })
```

## MWSResponse

Response received from MWS API

**Kind**: global typedef
**Properties**

| Name | Type | Description |
| --- | --- | --- |
| headers | `Object` | Headers of the response received from the _MWS API_. Those are typical `Headers` as you would find in the [`Fetch`] API. |
| status | `number` | Response status code |
| body | `Object` | Parsed body from _MWS API_ response |

## Options

Options for the new MWS client instanciation

**Kind**: global typedef
**Properties**

| Name | Type | Default | Description |
| --- | --- | --- | --- |
| AWSAccessKeyId | `string` | | AWS access key ID |
| MWSAuthToken | `string` | | MWS authentication token |
| SellerId | `string` | | Seller ID |
| \[SignatureVersion\] | `string` | `'2'` | Signature version used for signing to request URL |
| \[SignatureMethod\] | `string` | `'HmacSHA256'` | Signature method used for signing to request URL |
| \[userAgent\] | `string` | `'kaskadi-mws-client/VERSION (Language=node.js)'` | User agent used when sending request |
| \[parserType\] | `string` | `'xml'` | Parser used for the response received from MWS. Accepted values: `'xml'`, `'text'` |

# Notes

## Throttling

This client **does not** include throttling handling. The reason being that our internal implementation uses `Lambda` functions which are not persistent and therefore instantiate a new client at each function call. This makes a throttling handled via client irrelevant since multiple clients may be instantiated in a short period of time (or even in parallel) to call the same endpoint which leads to a client throttling state not reflecting the actual throttling state of the _MWS API_.

We encourage you to implement your own throttling handling in your infrastructure so that it fits your implementation. You can refer to [_MWS API_ documentation](https://docs.developer.amazonservices.com/en_UK/dev_guide/DG_Throttling.html) for more information on this.

_Reminder:_ response headers are exposed via the `mws-client` return value so you may use those to handle an hourly capped endpoint.

## Client implementation

This client uses **_signed requests_** to communicate with the _MWS API_. See docs [here](https://docs.developer.amazonservices.com/en_UK/dev_guide/DG_QueryString.html) and [there](https://docs.developer.amazonservices.com/en_UK/dev_guide/DG_SigningQueryRequest.html) for more details.
