fetchByMerchantTransactionId method returns one or more Chargeback objects for the transaction whose ID assigned by you (merchantTransactionId) matches the input. Multiple chargebacks may be associated with one transaction, because a customer can charge back a transaction’s line items separately.
Input
srd: sparse response description, a SOAP string (which must be a JSON object), in which you specify the elements you want returned.This parameter enables the calling system to constrain amethod call to return only components you specify. This gives you greater control over returned content, and improves response time within the Vindicia platform by reducing the processing needed for the call.
Some fields are required, either practically or in the WSDL, and will be returned regardless of the srd. A null srd returns the complete response.
merchantTransactionId: your ID (merchantTransactionId) of the transaction whose chargebacks you wish to fetch.
Output
return: an object of typeReturn that indicates the success or failure of the call.
chargebacks: an array of one or more Chargebacks associated with the transaction whose ID matches the one specified as the input parameter.
