This parameter contains the Version details. This is the version number of the API code that you are programming against (for example, 1149). The version you specify for a call has the following basic effects:

  • Indicates the version of the code lists and other data that eBay should use to process your request
  • Indicates the schema version you are using
  • Version must still be specified in individual requests included in the payload, such as AddFixedPriceItem requests
