AutoBill’s VID. If you provide the VID for any item in the AutoBill’s upgrade history, Subscribe will return the entire series of upgrades.
Note that the VID changes each time a customer upgrades the AutoBill. Use fetchAutoBillUpgradeHistoryBy to generate a complete list of VIDs for the AutoBill.
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 ID for any revision in the AutoBill’s upgrade history.
Output
return: an object of typeReturn that indicates the success or failure of the call.
upgradeHistorySteps: an array of steps or revisions in the AutoBill’s history. The AutoBillUpgradeHistoryStep object contains
vid: the Vindicia ID for the object,startTimestamp: the date and time the step began, andendTimestamp: the date and time the step ended. This time stamp is omitted if the step is current.
