The text below is what I have in the "Insert form URL" 'Specify cURL Options' field (except for changing the phone numbers, SID & ACCOUNT).
It works fine when I hardcode the "To=" phone number. I cannot get it working when changing the "To=" phone number to a variable.
--data-urlencode Body=This phone is now registered for XYZ. If you did not register this phone, text +11234567890 to report misuse.
I have tried everything I can think of to replace the "To=" phone number with a variable to no avail. I even read the doc on the FM Support site a few times!
Your help is sincerely appreciated.
