fetchByVid method returns a PaymentMethod object whose VID matches the input.
VID is Vindicia’s unique identifier for a PaymentMethod object. While creating a PaymentMethod object, do not specify a VID for it yourself. When Subscribe receives a PaymentMethod object in a call, such as PaymentMethod.update() or Transaction.AuthCapture(), if no VID or merchantPaymentMethodId exists inside the object, Subscribe creates a new PaymentMethod object and assigns it a VID. Retrieve this VID from the PaymentMethod object Subscribe returns to you in response to your call. Then, you may identify the object with the VID, and retrieve it by calling this method.
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.
vid: the PaymentMethod object’s Vindicia identifier, which serves as the search criterion.
Output
return: an object of typeReturn that indicates the success or failure of the call.
paymentMethod: the PaymentMethod object whose VID matches the input.
