We have an AMP form on one of our pages that posts to a Zapier webhook endpoint. The data is being sent to Zapier just fine but the response from Zapier has an improperly formatted header that causes the AMP-form to throw an error. This, in turn, stops the submit button from being disabled and is causing some users to inadvertently submit multiple identical forms.
Does anyone out there have experience using Zapier webhooks with AMP-forms? Any help would be greatly appreciated.
