For seller applications only
A hybrid Selling Partner API application is an application that can make calls both to the Selling Partner API and to Amazon Marketplace Web Service (Amazon MWS). Use a hybrid application when your solution requires functionality from both services. When a selling partner authorizes your hybrid Selling Partner API application, they are (1) authorizing your Amazon MWS developer ID to make calls to Amazon MWS on their behalf, and (2) authorizing the application to make calls to the Selling Partner API on their behalf.
Amazon considers a hybrid application to be a single application. For example, when you publish a hybrid application to the Amazon Seller Central Partner Network, you manage it as a single application.
# To create a hybrid application
Note: Application registration is an irreversible process that changes the authorization model. If you are updating a hybrid application, make sure that you have implemented OAuth authorization before registering your application. See the Authorization API Use Case Guide for more information.
Publish your Amazon MWS application to the Amazon Seller Central Partner Network. For information about publishing your application, see Amazon Seller Central Partner Network Listing Guide (opens new window) in the Amazon MWS documentation.
Sign into Seller Central using the credentials that you used to register as a developer.
In the Partner Network menu, click Develop Apps.
The Developer Central page appears.
Next to your Amazon MWS application, click Edit app.
Follow the instructions to register your application.
After creating a hybrid application you can:
Set up and test an OAuth authorization workflow. For more information, see Authorizing Selling Partner API applications.
Migrate existing Amazon MWS authorizations to your hybrid Selling Partner API application. For more information, see the Authorization API use case guide.
