I use Twilio through some other software we have written so I do have active Twilio account/subaccounts.
I am trying to set up sending SMS via Twilio from a workflow for the first time.
I believe I have the Twilio Account SID and Twilio Auth Token set up correctly
These come from the Sub Account which holds the number we wish to use.
When sending a message via Twilio - there is no record of the message in Twilio logs and of course I don't receive an SMS.
it's not clear how to debug this.
I have tried both Send From SID, and Send from Number (the SID being the SID of the number not the subaccount)
I assume that is correct or you couldn't pick a specific number to the send from.
Any suggestion pointers would be welcome.
