activate method to start an existing AutoBill that was created with a deferred start date (unknownStart = True) and is in status: Pending Activation. Calling activate sets the startTimestamp to today and initiates the billing process.
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.
auth: credentials required to authenticate this request.
autobill: the object of type AutoBill to activate.
Output
status: the status of the activatedAutoBill.
return: an object of type Return that indicates the success or failure of the call.
