Webhook Error - Zapier - ZohoCRM & Cudasign

Webhook Error - Zapier - ZohoCRM & Cudasign

ZohoCRM Enterprise and Zapier are not working together for an Instant Trigger.

I have set up an automation rule & webhook for an instant trigger using Zapier to autosend a document template from Cudasign when a specific field is updated within ZohoCRM. Unfortunately, Zapier can only get an error response from Zoho after a few hours of spinning wheel (left it in working in the background).

I have successfully set up other Zaps to this instance of Zoho and Cudasign that are based on NEW LEADS being posted an these other zaps function perfectly. The issue seems to be with the "Instant" zap associated with the "Enterprise Version" of ZohoCRM.

Here are a few things I checked on to make sure it isn't a user error:
1. Enterprise ZohoCRM is my version
2. Zapier is connected to both Cudasign and ZohCRM and all other zaps work
3. The webhook URL is connecting the Rule in the "Lead" module to Zapier is correct
4. I created multiple trigger fields using different types of fields (string, checkbox etc) and none of them work

The issue really seems to be Zapier not being able to connect to ZohoCRM for an instant trigger. Zapier attempted to connect to Zoho for hours until eventually, ZohoCRM Enterprise addition responded with an "Error" response.
