AddToWatchList
This call is used to add one or more items to a user's My eBay Watch list. The My eBay Watch list can be viewed on the user's My eBay page, or the list can be retrieved using GetMyeBayBuying.
Note: Only active listings can be added to a Watch list. If a user was watching an item when the listing ended, that item will be added back to the user's Watch list if the item is relisted.
Usage Details
Call AddToWatchList with one or more ItemID fields. Each active item is added to the user's Watch list.
The call response contains two fields, WatchListCount and WatchListMaximum. You can use these values to determine how many items are currently being watched, and how many available spaces are left in the user's Watch list.
Testing AddToWatchList
Test AddToWatchList in the Sandbox:
- Find an item on the My eBay Sandbox page (http://sandbox.ebay.com) and get the ItemID value.
- Make a call to AddToWatchList on behalf of a test user, adding the Sandbox item to the user's My eBay Watch list.
- Verify that the item is in the Watch list in one of two ways:
- Sign-in to the Sandbox as the test user and look for the item in the Watch list on the My eBay page.
- Use GetMyeBayBuying to retrieve the user's Watch list, and verify that the item is included in the list.

Argument | Type | Occurrence | Meaning |
---|
Call-specific Input Fields [Jump to standard fields] |
ItemID | ItemIDType (string) | Conditional,
repeatable: [0..*] |
The unique identifier of the single-variation listing that is to be added to the eBay user's Watch List. The item must be a currently active item, and the total number of items in the user's Watch List (after the items in the request have been added) cannot exceed the maximum allowed number of Watch List items. One or more ItemID fields can be specified. A separate error node will be returned for each item that was not successfully added to the Watch List. The user must use either one or more ItemID values or one or more VariationKey containers, but the user may not use both of these entities in the same call. |
VariationKey | VariationKeyType | Conditional,
repeatable: [0..*] |
This container is used to specify one or more item variations in a multi-variation, fixed-price listing that you want to add to the Watch List. The listing is identified through the ItemID value and each item variation existing within that listing is identified through a VariationSpecifics.NameValueList container. The user must use either one or more ItemID values or one or more VariationKey containers, but the user may not use both of these entities in the same call. |
VariationKey.ItemID | ItemIDType (string) | Conditional | The unique identifier of the fixed-price listing whose variation(s) should be added to or removed from the watch list. |
VariationKey .VariationSpecifics |
NameValueListArrayType | Conditional | This container is used to identify one or more item variations within the multiple-variation listing. If the specified name-value pairs do not match any item variation, the call behaves as if no variations were specified. |
VariationKey .VariationSpecifics .NameValueList |
NameValueListType | Conditional,
repeatable: [0..*] |
For the AddItem family of calls: Contains the name and value(s) for an Item Specific. Only required when the ItemSpecifics container is specified. For the AddFixedPriceItem family of calls: The same NameValueList schema is used for the ItemSpecifics node, the VariationSpecifics node, and the VariationSpecifcsSet node. If the listing has variations, any name that you use in the VariationSpecifics and VariationSpecificsSet nodes can't be used in the ItemSpecifics node. When you list with Item Variations:
For PlaceOffer: Required if the item being purchased includes Item Variations. For AddToWatchList and RemoveFromWatchList: The ItemID value of the multiple-variation listing and the name-value pair to identify each variation in the listing are required. Note: As of August 30, 2018, California will require sellers to display a Proposition 65 warning on online retail sites if products contain chemicals and/or substances that may impact the health of California buyers. This requirement is applicable to most eBay US categories, including eBay Motors, Motors Parts & Accessories, and catalog-enabled categories. The warning message can be customized by the seller, but should contain the following basic information:
|
VariationKey .VariationSpecifics .NameValueList.Name |
string | Conditional |
Depending on the call and context, this value is either a name of an Item/Variation Specific, or a Parts Compatibility name. For the AddItem and AddFixedPriceItem families of calls: In the Item.ItemSpecifics context, the value in this field will either be the name of a required/recommended/optional item specific name for the category, or it may be a seller's customized item specific name. For the AddFixedPriceItem family of calls: In the Compatibility.NameValueList context, this value is a motor vehicle aspect such as Year, Make, and Model. A Compatibility.NameValueList container is applicable for motor vehicle parts and accessories listings. For PlaceOffer: Required if the line item being purchased is an item variation within a multiple-variation listing. Note: For required and recommended item specifics that are returned in the getItemAspectsForCategory method of the Taxonomy API, the seller should pass in the name of these item specifics just as they are shown in the getItemAspectsForCategory response. Similarly, for catalog-enabled categories, the seller should pass in the name of instance aspects just as they are shown in the getItemAspectsForCategory response. Instance aspects are additional details unique to a specific item or listing that a seller can include along with the product aspects that are already defined in the eBay catalog product associated with the listing. Instance aspects common to many catalog-enabled categories include 'Bundle Description' and 'Modification Description'. eBay US sellers who ship to California are required to pass in a 'California Prop 65 Warning' item specific if the item in the listing contains one or more chemicals known to be harmful to human health. This item specific is passed at the listing level for both single-variation and multiple-variation listings. The 'California Prop 65 Warning' is considered an instance specific because it will be retained on the listing even when the seller lists using an eBay catalog product. The 'California Prop 65 Warning' may be applicable in most eBay US categories, including eBay Motors, Motors Parts & Accessories, and catalog-enabled categories. Note: If Brand and MPN (Manufacturer Part Number) are being used to identify product variations in a multiple-variation listing, the Brand must be specified at the item level (ItemSpecifics container) and the MPN for each product variation must be specified at the variation level (VariationSpecifics container). The Brand name must be the same for all variations within a single listing. Max length: 65. |
VariationKey .VariationSpecifics .NameValueList.Value |
string | Conditional,
repeatable: [0..*] |
Depending on the call and context, this value is either the value of an Item/Variation Specific, a Parts Compatibility value, or a product identifier. For the AddItem family of calls: Multiple values can only be specified for an Item Specific if the itemToAspectCardinality field of the getItemAspectsForCategory method shows a value of MULTI . If an item specific only supports a single value, only the first item specific value specified in the request will be used. For the Compatibility.NameValueList context, this is the corresponding value of a motor vehicle aspect such as Year, Make, and Model. A Compatibility.NameValueList container is applicable for motor vehicle parts and accessories listings. For PlaceOffer: Required if the line item being purchased is an item variation within a multiple-variation listing. Note: The standard maximum length for the value of an item specific is 65, but the maximum allowed length increases for instance aspects such as 'Bundle Description' and 'Modification Description'. For item specifics with max lengths greater than 65, the actual max length will be returned in a corresponding aspectMaxLength field. The maximum allowed length for the new 'California Prop 65 Warning' item specific is 800 characters. For more information about the 'California Prop 65 Warning' item specific, see the ItemSpecifics.NameValueList field description. Max length: 50. |
Standard Input Fields |
ErrorLanguage | string | Optional |
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.
|
||||||||||||||||||||||||||||||||||||||||
MessageID | string | Optional |
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. |
||||||||||||||||||||||||||||||||||||||||
Version | string | Conditional |
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:
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.) See:
|
||||||||||||||||||||||||||||||||||||||||
WarningLevel | WarningLevelCodeType | Optional |
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. Applicable values: High if the user wishes to receive warnings when the application passes unrecognized or deprecated elements in an API call request. Setting the WarningLevel value to High is not recommended in a production environment. Instead, it should only be used during the development/debugging stage.Low if the user does not wish to receive warnings when the application passes unrecognized or deprecated elements in an API call request. This is the default value if WarningLevel is not specified in the call request.See Warning Level. |

Call-specific Output Fields [Jump to standard fields] |
WatchListCount | int | Always | This integer value indicates the total number of items in the user's Watch List (after those specified in the call request have been successfully added). |
WatchListMaximum | int | Always | This integer value indicates the maximum number of items allowed in a user's Watch List. The maximum number of items that can be added to a Watch List is 400, but this can vary by eBay marketplace. |
Standard Output Fields |
Ack | AckCodeType | Always |
A token representing the application-level acknowledgement code that indicates the response status (e.g., success). The AckCodeType list specifies the possible values for the Ack field.
Applicable values: (Not all values in AckCodeType apply to this field.) Code so that your app gracefully handles any future changes to this list. |
Build | string | Always | This refers to the specific software build that eBay used when processing the request and generating the response. This includes the version number plus additional information. eBay Developer Support may request the build information when helping you resolve technical issues. |
CorrelationID | string | Conditionally |
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. |
Errors | ErrorType | Conditionally,
repeatable: [0..*] |
A list of application-level errors (if any) that occurred when eBay processed the request. |
Errors.ErrorClassification | ErrorClassificationCodeType | Conditionally |
API errors are divided between two classes: system errors and request errors.
Applicable values: Code so that your app gracefully handles any future changes to this list. |
Errors.ErrorCode | token | Conditionally |
A unique code that identifies the particular error condition that occurred. Your application can use error codes as identifiers in your customized error-handling algorithms.
See Errors By Number. |
Errors.ErrorParameters | ErrorParameterType | Conditionally,
repeatable: [0..*] |
This optional element carries a list of context-specific error variables that indicate details about the error condition. These are useful when multiple instances of ErrorType are returned. |
Errors.ErrorParameters [ attribute ParamID ] |
string | Conditionally | This optional element carries a list of context-specific error variables that indicate details about the error condition. These are useful when multiple instances of ErrorType are returned. |
Errors.ErrorParameters.Value | string | Conditionally | This is the value of the request parameter noted in the ParamID attribute. So, if the ParamID value was ItemID, the value in this field would be the actual value of that ItemID. |
Errors.LongMessage | string | Conditionally | A more detailed description of the condition that raised the error. |
Errors.SeverityCode | SeverityCodeType | Conditionally |
Indicates whether the error is a severe error (causing the request to fail) or an informational error (a warning) that should be communicated to the user.
Applicable values: If the source of the problem is within the application (such as a missing required element), change the application before you retry the request.
See the Error handling section of the Making a Trading API call guide for more information. When a warning occurs, the error is returned in addition to the business data. In this case, you do not need to retry the request (as the original request was successful). However, depending on the cause or nature of the warning, you might need to contact either the end user or eBay to effect a long term solution to the problem to prevent it from reoccurring in the future. Code so that your app gracefully handles any future changes to this list. |
Errors.ShortMessage | string | Conditionally | A brief description of the condition that raised the error. |
HardExpirationWarning | string | Conditionally | Expiration date of the user's authentication token. Only returned within the 7-day period prior to a token's expiration. To ensure that user authentication tokens are secure and to help avoid a user's token being compromised, tokens have a limited life span. A token is only valid for a period of time (set by eBay). After this amount of time has passed, the token expires and must be replaced with a new token. |
Timestamp | dateTime | Always |
This value represents the date and time when eBay processed the request. The time zone of this value is GMT and the format is the ISO 8601 date and time format (YYYY-MM-DDTHH:MM:SS.SSSZ). See the Time Values section in the eBay Features Guide for information about this time format and converting to and from the GMT time zone. Note: GetCategories and other Trading API calls are 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, this time value reflects the time the cached response was created. Thus, this value is not necessarily when the request was processed. 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, this time value does reflect when the request was processed. |
Version | string | Always | The version of the response payload schema. Indicates the version of the schema that eBay used to process the request. See the Standard Data for All Calls section in the eBay Features Guide for information on using the response version when troubleshooting CustomCode values that appear in the response. |

Adds an item (or items) to a buyers Watch List.
Description
Using the Finding API, a potential buyer has found several Harry Potter books that she is interested in buying. The seller's book (M*****l B********r) is of particular interest and the potential buyer wants to keep an eye on the auction's progress.
Using AddToWatchList, the potential buyer adds the Harry Potter book to her Watch List. The call returns the current number of items on her Watch List, along with the maximum number of items that she can watch at a time. Subtract the WatchListCount value from WatchListMaximum to calculate how many additional watches potential buyer can add to her watch list.
