fetchByVid method returns an Account object whose VID matches the input. When you first create an Account object with the update method, leave the VID field empty; Subscribe automatically assigns the object a VID. For convenience, store the VID in your application so that you can retrieve or refer to that object with its VID later. If you do not assign unique account IDs (merchantAccountId) yourself, you may identify Account objects with their VIDs.
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 Account 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.
account: the Account object whose VID matches the input.
