Hello, 

I am trying to send a webhook when certain fields in a contact have changed. I know that I can send a webhook with a workflow rule. However, the number of fields in a contact that should trigger this workflow rule exceeds the maximum number of allowed fields. 

So I guess I have to solve this via function or something like that. 

How can I do this? Trigger/send a webhook when 10 fields in a contact have changed? 

Thanks for help
