This method is used by the seller to update an existing evidence set for a payment dispute with one or more evidence files. 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 unique identifier of the evidence set to update is specified through the evidenceId field, and the file(s) to add are identified through the files array in the request payload. The unique identifier for an evidence file is automatically generated and returned in the fileId field of the uploadEvidence response payload upon a successful call. Sellers must make sure to capture the fileId value for each evidence file that is uploaded with the uploadEvidence method.

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 http status code of 204 Success is returned. There is no response payload unless an error occurs. To verify that a new file is a part of the evidence set, the seller can use the fetchEvidenceContent method, passing in the proper evidenceId and fileId values.
