AbstractRequestType

This container is only used by the PlaceOffer call request if the previous PlaceOffer call resulted in a BotBlock container in the response. If the caller receives this container in the response, that caller must make another PlaceOffer call, this time, passing in the encrypted token and URL that is returned in the BotBlock container in the response. This safeguard lets eBay know that a real user is making a PlaceOffer call and not a bot.

Detail levels are instructions that define standard subsets of data to return for particular data components (e.g., each Item, Transaction, or User) within the response payload. For example, a particular detail level might cause the response to include buyer-related data in every result (e.g., for every Item), but no seller-related data.

Specifying a detail level is like using a predefined attribute list in the SELECT clause of an SQL query. Use the DetailLevel element to specify the required detail level that the client application needs pertaining to the data components that are applicable to the request.

The DetailLevelCodeType defines the global list of available detail levels for all request types. Most request types support certain detail levels or none at all. If you pass a detail level that exists in the schema but that isn't valid for a particular request, eBay ignores it and processes the request without it.

For each request type, see the detail level tables in the Input/Output Reference to determine which detail levels are applicable and which elements are returned for each applicable detail level.

Note that DetailLevel is required input for GetMyMessages.

With GetSellerList and other calls that retrieve large data sets, please avoid using ReturnAll when possible. For example, if you use GetSellerList, use GranularityLevel instead, or use GetSellerEvents. If you do use 'ReturnAll' with GetSellerList, use a small Pagination.EntriesPerPage value and a narrow EndTimeFrom/EndTimeTo date range for better performance.

The public IP address of the machine from which the request is sent. Your application captures that IP address and includes it in a call request. eBay evaluates requests for safety (also see the BotBlock container in the request and response of this call).

Error tolerance level for the call. This is a preference that specifies how eBay should handle requests that contain invalid data or that could partially fail. This gives you some control over whether eBay returns warnings or blocking errors and how eBay processes the invalid data.

This field is only applicable to AddItem and related calls, and only when the listing includes ProductListingDetails.

Use ErrorLanguage to return error strings for the call in a different language from the language commonly associated with the site that the requesting user is registered with. Below are some examples from different countries.

A unique identifier for a particular call. If the same InvocationID is passed in after it has been passed in once on a call that succeeded for a particular application and user, then an error will be returned. The identifier can only contain digits from 0-9 and letters from A-F. The identifier must be 32 characters long. For example, 1FB02B2-9D27-3acb-ABA2-9D539C374228.

Most Trading API calls support a MessageID element in the request and a CorrelationID element in the response. If you pass in a MessageID in a request, the same value will be returned in the CorrelationID field in the response. Pairing these values can help you track and confirm that a response is returned for every request and to match specific responses to specific requests. If you do not pass a MessageID value in the request, CorrelationID is not returned.

Note: GetCategories is designed to retrieve very large sets of metadata that change once a day or less often. To improve performance, these calls return cached responses when you request all available data (with no filters). When this occurs, the MessageID and CorrelationID fields aren't applicable. However, if you specify an input filter to reduce the amount of data returned, the calls retrieve the latest data (not cached). When this occurs, MessageID and CorrelationID are applicable.

You can use the OutputSelector field to restrict the data returned by a call. This field can make the call response easier to manage, especially when a large payload is returned. If you use the OutputSelector field, the output data will only include the field(s) you specified in the request, as well as all of its child fields (if a field is a container) and its parent fields (if any). Note that it is possible that a field included through an OutputSelector field may still not be returned if it is not applicable, or if it is not found based on other criteria set up in the request payload.

For example, if you are using GetItem and you only want to retrieve the URL of the View Item page (emitted in ViewItemURL field) and the item's Buy It Now price (emitted in BuyItNowPrice field), you would include two separate OutputSelector fields and set the value for each one as ViewItemURL and BuyItNowPrice as in the following example:

 If the following output selectors are used: 

...
 <OutputSelector>ViewItemURL</OutputSelector>
 <OutputSelector>BuyItNowPrice</OutputSelector> 
... 

 ...the response might look like the following 

  <Item>
 <BuyItNowPrice currencyID="USD">0.0</BuyItNowPrice>
 <ListingDetails>
 <ViewItemURL>http://www.ebay.com/itm/Tag-Heuer-Mens-Watch/182879833261</ViewItemURL>
 </ListingDetails>
 </Item>  

The version number of the API code that you are programming against (e.g., 1149). The version you specify for a call has these basic effects:

• It indicates the version of the code lists and other data that eBay should use to process your request.
• It indicates the schema version you are using.

You need to use a version that is greater than or equal to the lowest supported version.
For the SOAP API: If you are using the SOAP API, this field is required. Specify the version of the WSDL your application is using.

For the XML API: If you are using the XML API, this field has no effect. Instead, specify the version in the X-EBAY-API-COMPATIBILITY-LEVEL HTTP header. (If you specify Version in the body of an XML API request and it is different from the value in the HTTP header, eBay returns an informational warning that the value in the HTTP header was used instead.)

Controls whether or not to return warnings when the application passes unrecognized or deprecated elements in a request.

An unrecognized element is one that is not defined in any supported version of the schema. Schema element names are case-sensitive, so using WarningLevel can also help you remove any potential hidden bugs within your application due to incorrect case or spelling in field names before you put your application into the Production environment.

WarningLevel only validates elements; it doesn't validate XML attributes. It also doesn't control warnings related to user-entered strings or numbers, or warnings for logical errors.

We recommend that you only use this during development and debugging. Do not use this in requests performed in the Production environment.
