| MWS | 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
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
})A section of MWS API. Note: all sections and associated endpoints are generated automatically when instanciating a new client
Kind: global class
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¶m.2=bar) |
Example
// 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' })Response received from MWS API
Kind: global typedef
Properties
| Name | Type | Description |

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 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.
This client uses signed requests to communicate with the MWS API. See docs here and there for more details.
All items listed here point to the MWS API docs
