We've created a Webhook that fires when a form is filled out, and the webhook creates a case in Salesforce.
While testing the form, I'm able to get the webhook to fire if the lead is new to the system. However if it's an existing lead, the webhook is firing and returning a 200 code (which should be success), however the case isn't in Salesforce.
The form that fires the webhook is for existing clients, so none will be new to the system. Is there a way around this – getting the webhook to create a SFDC case for existing leads that submit a form?
