I then disabled the CREATE workflow rule and created a new rule to execute on CREATE or EDIT and setup the webhook in the same way. This resulted in a new account being entered in the Zoho Creator app whenever a CRM record is changed. Initially I thought that EDIT would refer tho the existing record in the Creator app being updated with information that was changed in the CRM rather than a duplicate being created though given the URL specified in the webhook is  https://creator.zoho.com/api/<ownername>/<format>/<applicationName>/form/<formName>/record/add/ it's understandable (yet confusing) that all data that is sent from the CRM is added.

So at this point I disable the CREATE or EDIT workflow rule and reactive the initial CREATE rule. I then create a second workflow rule which executes on EDIT and follow these instructions  https://www.zoho.com/creator/help/api/rest-api/rest-api-edit-records.html noting that the URL used in the webhook is now  https://creator.zoho.com/api/<ownername>/<format>/<applicationName>/form/<formName>/record/update/. And when a record is edited in the CRM the result in the Creator app...... NOTHING

Should I be able to have a NEW record created in the CRM be sent to the Creator app and then have any subsequent updates to that CRM record update without any duplication in Creator?
