In zoho subscriptions when a new subscriptions is created a new record must be created in creator with fields as subscription id and customer id. As there is no automation(custom function) in zoho subscription how can i do this.

On using webhook it only creates an empty record in zoho creator.

How can I pass the event data(Subscriptions data) to a multiline field in zoho creator and I will do the rest via scripts of creator .Please help me to frame the url with event data  for webhook
