Signing API requests
All of your API calls must be signed for them to work properly.
To sign your API requests, you need Amazon MWS keys. To get the keys, sign in to Seller Central, click Integration, and then click MWS Access Key.
For more information about how to configure your services to make signed API calls, see the Signature parameter in the Required Request Parameters section of the Amazon MWS Developer Guide.
Note: If you are using Amazon Pay SDKs, signing your API calls is handled for you.
