RespondToBestOffer

This call enables the seller to accept or decline a buyer's Best Offer on an item, or make a counter offer to the buyer's Best Offer. A seller can decline multiple Best Offers with one call, but the seller cannot accept or counter offer multiple Best Offers with one call. Best Offers are not applicable to auction listings.

Note: Historically, the Best Offer feature has not been available for auction listings, but beginning with Version 1027, sellers in the US, UK, and DE sites are able to offer the Best Offer feature in auction listings. The seller can offer Buy It Now or Best Offer in an auction listing, but not both.

See Best Offer.

See also the reference documentation for this call:

GetBestOffers - This call can be used by a seller to retrieve all active Best Offers, all Best Offers on a specific listing, a specific Best Offer for a specific listing, or Best Offers in a specific state.

Argument	Type	Occurrence	Meaning

Call-specific Input Fields [Jump to standard fields]

Action	BestOfferActionCodeType	Required	The enumeration value that the seller passes in to this field will control whether the seller accepts or make a counter offer to a single buyer's Best Offer, or declines one or more buyers' Best Offers. A seller can decline multiple Best Offers with one call, but the seller cannot accept or counter offer multiple Best Offers with one call. Applicable values: Accept (in) This value should be passed in to the Action field to accept the Best Offer identified in the BestOfferID field. Note that only one Best Offer may be accepted in a single RespondToBestOffer call. Counter (in) This value should be passed in to the Action field to counter a buyer's Best Offer or Counter Offer. Note that a seller may only counter one Best Offer in a single RespondToBestOffer call. If a seller is using the RespondToBestOffer call to counter a Best Offer, the counter offer price must be specified in the CounterOfferPrice field, and the quantity of items in the Best Offer must be specified in the CounterOfferQuantity field. CustomCode (in) Reserved for internal or future use. Decline (in) This value should be passed in to the Action field to decline one or more Best Offers identified by one or more BestOfferID fields. Note that multiple Best Offers may be declined in a single RespondToBestOffer call.
BestOfferID	BestOfferIDType (string)	Required, repeatable: [1..*]	The unique identifier of a buyer's Best Offer for the order line item. This ID is created once the buyer makes a Best Offer. It is possible that a seller will get multiple Best Offers for an order line item, and if that seller would like to decline multiple/all of the Best Offers with one RespondToBestOffer call, the seller would pass in each of these identifiers in a separate BestOfferID field. However, the seller can only accept or counter offer one Best Offer at a time.
CounterOfferPrice	AmountType (double)	Conditional	The seller inserts counter offer price into this field. This field is conditionally required and only applicable when the Action value is set to `Counter`, The counter offer price cannot exceed the Buy It Now price for a single quantity item. However, the dollar value in this field may exceed the Buy It Now price if the buyer is requesting or the seller is offering multiple quantity of the item (in a multiple-quantity listing). The quantity of the item must be specified in the CounterOfferQuantity field if the seller is making a counter offer.
CounterOfferPrice [ attribute currencyID ]	CurrencyCodeType	Optional	The seller inserts counter offer price into this field. This field is conditionally required and only applicable when the Action value is set to `Counter`, The counter offer price cannot exceed the Buy It Now price for a single quantity item. However, the dollar value in this field may exceed the Buy It Now price if the buyer is requesting or the seller is offering multiple quantity of the item (in a multiple-quantity listing). The quantity of the item must be specified in the CounterOfferQuantity field if the seller is making a counter offer. For a list of possible enumeration values, see CurrencyCodeType.
CounterOfferQuantity	int	Conditional	The seller inserts the quantity of items in the counter offer into this field. This field is conditionally required and only applicable when the Action value is set to `Counter`, The counter offer price must be specified in the CounterOfferPrice field if the seller is making a counter offer. This price should reflect the quantity of items in the counter offer. So, if the seller's counter offer 'unit' price is 15 dollars, and the item quantity is '2', the dollar value passed into the CounterOfferPrice field would be `30.0`.
ItemID	ItemIDType (string)	Required	The unique identifier of the listing to which the seller is responding to a Best Offer.
SellerResponse	string	Conditional	This optional text field allows the seller to provide more details to the buyer about the action being taken against the buyer's Best Offer. Max length: 250.

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:

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.)

See:
    HTTP headers
    eBay Schema Versioning Strategy
    Lowest Supported Version

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

(in) The WarningLevel value is set to 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

(in) The WarningLevel value is set to 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.

Return Value	Type	Occurrence	Meaning

Call-specific Output Fields [Jump to standard fields]

RespondToBestOffer	BestOfferArrayType	Always	The BestOffer.CallStatus value returned in this container will indicate whether or not the action specified in the call request (accept, decline, or counter offer) was successful. The accept and counter offer actions can only be applied toward a single Best Offer. However, multiple Best Offers on a listing can be declined with one call. All Best Offers must be successfully declined with the RespondToBestOffer call for the BestOffer.CallStatus value to be `Success`.
RespondToBestOffer.BestOffer	BestOfferType	Always, repeatable: [1..*]	For GetBestOffers, each BestOffer container consists of detailed information on the Best Offer/Counter Offer, including the type of Best Offer (Best Offer, Buyer/Seller Counter Offer), amount of the Best Offer/Counter Offer, and status of Best Offer/Counter Offer. For RespondToBestOffer, each BestOffer container provides the status ('Success' or 'Failure') of the Best Offer action (Accept, Counter, or Decline), which are defined in BestOfferActionCodeType.
RespondToBestOffer.BestOffer .CallStatus	string	Always	The value in this field (`Success` or `Failure`) will indicate whether or not the seller's attempt to accept, decline, or counter offer a Best Offer was successful. This field is only used by the RespondToBestOffer response.

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: CustomCode (out) Reserved for internal or future use. Failure (out) This value indicates that the call request processing failed. Success (out) This value indicates that the call request was processed successfully without any issues. Warning (out) This value indicates that the call request was successful, but processing was not without any issues. These issues can be checked in the Errors container, that will also be returned when one or more known issues occur with the call request. (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: CustomCode (out) Reserved for internal or future use. RequestError (out) An error has occurred either as a result of a problem in the sending application or because the application's end-user has attempted to submit invalid data (or missing data). In these cases, do not retry the request. The problem must be corrected before the request can be made again. If the problem is due to something in the application (such as a missing required field), the application must be changed. If the problem is a result of end-user data, the application must alert the end-user to the problem and provide the means for the end-user to correct the data. Once the problem in the application or data is resolved, resend the request to eBay with the corrected data. SystemError (out) Indicates that an error has occurred on the eBay system side, such as a database or server down. An application can retry the request as-is a reasonable number of times (eBay recommends twice). If the error persists, contact Developer Technical Support. Once the problem has been resolved, the request may be resent in its original form. 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: CustomCode (out) Reserved for internal or future use. Error (out) The request that triggered the error was not processed successfully. When a serious application-level error occurs, the error is returned instead of the business data. If the source of the problem is within the application (such as a missing required element), change the application before you retry the request. If the problem is due to end-user input data, please alert the end-user to the problem and provide the means for them to correct the data. Once the problem in the application or data is resolved, you can attempt to re-send the request to eBay. If the source of the problem is on eBay's side, An application can retry the request as-is a reasonable number of times (eBay recommends twice). If the error persists, contact Developer Technical Support. Once the problem has been resolved, the request may be resent in its original form. See the Error handling section of the Making a Trading API call guide for more information. Warning (out) The request was processed successfully, but something occurred that may affect your application or the user. For example, eBay may have changed a value the user sent in. In this case, eBay returns a normal, successful response and also returns the warning. 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.
