getProductMetadataBulk

Note: This call is deprecated, and will be decommissioned on March 31st, 2025.

Use this call to find the product metadata needed to add a product to the eBay catalog for a specified category.

All eBay Electronics categories require sellers to list with a product whenever there's a product match in the associated eBay catalog. Some other categories also require listing with a product. When listing with a product is required and the catalog does not contain a matching product, the seller must add the product to the catalog before listing.

You use this call to retrieve the product metadata for a given category. In turn, this product metadata is used to construct an addProducts call (Product API) for submitting new products for inclusion into an eBay catalog. Product metadata consists of the property names and the related value constraints used to construct the name-value pairs that describe a product.

Note: This call is not supported in the Sandbox environment. Product creation is supported in production for a subset of categories on the US (global ID EBAY-US) and UK (global ID EBAY-GB) sites only. Use GetCategoryFeatures in the Trading API to determine which categories support product creation.

See Product Creation for more information about when you should add a product to an eBay catalog, and how to do it.

Return Value	Type	Occurrence	Meaning

Call-specific Output Fields [Jump to standard fields]

productMetadataResponse	ProductMetadataResponse (BaseResponse)	Always, repeatable: [1..*]	Product metadata for the category specified in the corresponding productMetadataRequest in the request. Product metadata consists of individual property metadata, group properties, the metadata version, and the corresponding request.+++
productMetadataResponse.ack	AckValue	Always	Applicable values: Failure 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. PartialFailure The request that triggered the error was processed successfully but with some warnings. Success The request was processed successfully, but something occurred that may affect your application or the user. Warning The request that triggered the error was processed successfully but with some warnings.
productMetadataResponse .errorMessage	ErrorMessage	Conditionally	Description of an error or warning that occurred when eBay processed the request. Not returned if the ack value is Success.
productMetadataResponse .errorMessage.error	ErrorData	Conditionally, repeatable: [0..*]	Details about a single error.
productMetadataResponse .errorMessage.error.category	ErrorCategory	Conditionally	There are three categories of errors: request errors, application errors, and system errors. Applicable values: Application An error occurred due to a problem with the request, with the most likely source being the application sending the request. For example, the request is missing a required data element or it contains an invalid field. The problem must be corrected before the request can be resent. Inspect the error message to find the cause of the problem. If the problem is due to an application error, modify the application and resend the request. If the error is due to invalid data, the source of the data must be corrected before you resend the resend request to eBay. Request An error occurred due to a problem with the request, with the most likely source being missing or invalid data in the request. The problem must be corrected before the request can be retried. Inspect the error message to find the cause of the problem. If the problem is a result of end-user data, alert the end-user to the problem and provide the means for them to correct the problem. Once the problem is resolved, resend the request to eBay. System Indicates that an error has occurred on the eBay system side. For example, a database or server could be down. Inspect the error message to find the cause of the problem. If the problem is on the eBay 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.
productMetadataResponse .errorMessage.error.domain	string	Conditionally	Name of the domain in which the error occurred. domain values: Marketplace A business or validation error occurred in the service. SOA An exception occurred in the Service Oriented Architecture (SOA) framework.
productMetadataResponse .errorMessage.error.errorId	long	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.
productMetadataResponse .errorMessage.error .exceptionId	token	Conditionally	Unique identifier for an exception associated with an error.
productMetadataResponse .errorMessage.error.message	string	Conditionally	A detailed description of the condition that caused in the error.
productMetadataResponse .errorMessage.error.parameter	ErrorParameter (string)	Conditionally, repeatable: [0..*]	Various warning and error messages return one or more variables that contain contextual information about the error. This is often the field or value that triggered the error.
productMetadataResponse .errorMessage.error.parameter [ attribute name ]	string	Conditionally	Various warning and error messages return one or more variables that contain contextual information about the error. This is often the field or value that triggered the error.
productMetadataResponse .errorMessage.error.severity	ErrorSeverity	Conditionally	Indicates whether the reported problem is fatal (an error) or is less- severe (a warning). Review the error message details for information on the cause. If the request fails and the application is the source of the error (for example, a required element is missing), update the application before you retry the request. If the problem is due to incorrect user data, 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, re-send the request to eBay. If the source of the problem is on eBay's side, you can retry the request a reasonable number of times (eBay recommends you try the request twice). If the error persists, contact Developer Technical Support. Once the problem has been resolved, you can resend the request in its original form. If a warning occurs, warning information is returned in addition to the business data. Normally, you do not need to resend the request (as the original request was successful). However, depending on the cause of the warning, you might need to contact the end user, or eBay, to effect a long term solution to the problem. Applicable values: Error eBay encountered a fatal error during the processing of the request, causing the request to fail. When eBay encounters an error, it returns error data instead of the requested business data. Inspect the error details and resolve the problem before resubmitting the request. Warning The request was successfully processed, but eBay encountered a non-fatal error during the processing that could affect the data returned. For example, eBay might have changed the value of an input field. In this case, eBay returns a successful response, but it also returns a warning. For best results, requests should return without warnings. Inspect the warning details and resolve the problem before resubmitting the request.
