Product Advertising API requests can include up to two operations. These requests, called multiple operations requests, can be a combination of any number of simple and/or batch requests. The following figure shows how two simple requests can be combined into one multiple operations request, as shown in the following example.

The syntax to declare parameters in a multiple operations request is the same as it is in a batch request. A multiple operations request differs from a batch request in the definition of the Operation parameter. In a multiple operations request, the value of Operation is set to two, comma-separated operations.

Multiple operations requests can have only two different operations. One operation in the request, however, can be used as a batch operation so that it is used more than once. Extending the previous example, a valid multiple operations request could be as follows.

In this request, ItemLookup is called twice and SellerLookup is called once.
