 - `consumerId`: Your Walmart Consumer ID. Required if you are making requests to endpoints that use signature-based auth (see the [Authorization](#authorization) section)
 - `privateKey`: Your Walmart private key. Ditto the requirements for the `consumerId` option.
 - `channelType`: The channel type value you received during onboarding. Required in CA.
+- `partnerId`: Your Walmart Partner ID. Required when using the Supplier APIs.
 - `accessToken`: An instance of `Walmart\AccessToken`, containing an access token and its expiration time. If provided, this will be used instead of the client ID and secret to authenticate API calls, until the token expires. This is useful if you want to reuse an access token that you've already retrieved from Walmart. More details on access token auth [below](#access-token-auth).
 
 If you try to instantiate an instance of an API class that is not supported in the country you've specified, an exception will be thrown.

 This endpoint requires the following authorization methods:
 
 * `signatureScheme`: Request signature authentication. Request signatures are generated using a combination of request info, a timestamp, and your Walmart consumer ID and private key. The signature is passed in the WM_SEC.AUTH_SIGNATURE header. This is always used in tandem with consumer ID authentication (above). When using endpoints that require signature authentication, you must pass the `privateKey` and `consumerId` options to the `Configuration` constructor.
+* `partnerScheme`: Header authentication with your Walmart partner ID, which is passed in the WM_PARTNER.ID header. Required by Supplier API endpoints. When using endpoints that require partner ID authentication, you must pass the `partnerId` option to the `Configuration` constructor.
 * `consumerIdScheme`: Header authentication with your Walmart consumer ID, which is passed in the WM_CONSUMER.ID header. This is always used in tandem with signature authentication (below). When using endpoints that require consumer ID authentication, you must pass the `consumerId` option to the `Configuration` constructor.
 * `accessTokenScheme`: Header authentication with a Walmart access token, which is automatically generated using your Client ID and Client Secret. The token is valid for 15 minutes, and will be passed in the WM_SEC.ACCESS_TOKEN header
