Unable to connect to Zapier
I have used Zapier successfully with Sendy for years. Lately none of my Zaps are working although they don't show errors in the Zapier interface. Their tech support sent me the log file of one of my Zaps I use to update Salesforce when a customer unsubscribes from emails etc.
This is the log.
