This method is used by the seller to add one or more evidence files to address a payment dispute initiated by the buyer. The unique identifier of the payment dispute is passed in as a path parameter, and unique identifiers for payment disputes can be retrieved with the getPaymentDisputeSummaries method.

Note: All evidence files should be uploaded using addEvidence and updateEvidence before the seller decides to contest the payment dispute. Once the seller has officially contested the dispute (using contestPaymentDispute or through My eBay), the addEvidence and updateEvidence methods can no longer be used. In the evidenceRequests array of the getPaymentDispute response, eBay prompts the seller with the type of evidence file(s) that will be needed to contest the payment dispute.

The file(s) to add are identified through the files array in the request payload. Adding one or more new evidence files for a payment dispute triggers the creation of an evidence file, and the unique identifier for the new evidence file is automatically generated and returned in the evidenceId field of the addEvidence response payload upon a successful call.

The type of evidence being added should be specified in the evidenceType field. All files being added (if more than one) should correspond to this evidence type.

Upon a successful call, an evidenceId value is returned in the response. This indicates that a new evidence set has been created for the payment dispute, and this evidence set includes the evidence file(s) that were passed in to the fileId array. The evidenceId value will be needed if the seller wishes to add to the evidence set by using the updateEvidence method, or if they want to retrieve a specific evidence file within the evidence set by using the fetchEvidenceContent method.


Resource URI


This method is supported in Sandbox environment. To access the endpoint, just replace the root URI with

URI parameters

payment_dispute_idstringThis is the unique identifier of the payment dispute. This path parameter must be passed into the call URI to identify the payment dispute for which the user plans to add evidence for a contested payment dispute. This identifier is automatically created by eBay once the payment dispute comes into the eBay system. The unique identifier for payment disputes is returned in the paymentDisputeId field in the getPaymentDisputeSummaries response.

This path parameter is required, and the actual identifier value is passed in right after the payment_dispute resource. See the Resource URI above.

Request payload

Request fields

Input container/fieldTypeDescription

This field is used to indicate the type of evidence being provided through one or more evidence files. All evidence files (if more than one) should be associated with the evidence type passed in this field. See the EvidenceTypeEnum type for the supported evidence types.

Occurrence: Required

filesarray of FileEvidence

This array is used to specify one or more evidence files that will become part of a new evidence set associated with a payment dispute. At least one evidence file must be specified in the files array.

The unique identifier of an evidence file is returned in the response payload of the uploadEvidence method.

Occurrence: Required


If an uploadEvidenceFile call is successful, a unique identifier of this evidence file will be returned in the uploadEvidenceFile response payload. This unique fileId value is then used to either add this evidence file to a new evidence set using the addEvidence method, or to add this file to an existing evidence set using the updateEvidence method.

Note that if an evidence set already exists for a payment dispute, the getPaymentDispute method will return both the evidenceId (unique identifier of evidence set) value, and the fileId (unique identifier of a file within that evidence set) value(s).

Occurrence: Required

lineItemsarray of OrderLineItems

This required array identifies the order line item(s) for which the evidence file(s) will be applicable. Both the itemId and lineItemID fields are needed to identify each order line item, and both of these values are returned under the evidenceRequests.lineItems array in the getPaymentDispute response.

Occurrence: Required


The unique identifier of the eBay listing associated with the order.

Occurrence: Required


The unique identifier of the line item within the order. The lineItemId value is created once the buyer actually purchases the item, or if there is a commitment to buy (such as an auction that is won by the buyer, an accepted Best Offer, or other situation that does not require immediate payment from the buyer).

Occurrence: Required


HTTP response headers

This call has no response headers.

Response payload

Response fields

Output container/fieldTypeDescription

The value returned in this field is the unique identifier of the newly-created evidence set. Upon a successful call, this value is automatically genererated. This new evidence set for the payment dispute includes the evidence file(s) that were passed in to the fileId array in the request payload. The evidenceId value will be needed if the seller wishes to add to the evidence set by using the updateEvidence method, or if they want to retrieve a specific evidence file within the evidence set by using the fetchEvidenceContent method.

Occurrence: Always

Sample 1: Create an evidence set

In this call, the seller is creating a new evidence set with one new evidence file. The unique identifier of the payment dispute is passed in as a path parameter, and the evidence file is identified in the request payload.


After passing in the payment dispute ID as a path parameter, the request payload is used to identify the ID of the evidence file that will initiate the new evidence set, to identify the order line item, and to specify the type of evidence being provided.



With a successful call, the response payload shows the unique identifier of the new evidence set that was successfully create. This evidence set ID will be used if the seller wishes to add files to this evidence set using the updateEvidence method.
