SmsType (Optional): This optional parameter can be used to skip template addition on Exotel Dashboard and configure SMS type based on the template registered on DLT in India.
Possible values-
transactional (OTP or Service Implicit content)
transactional_opt_in (Service Explicit content)

If not set or incorrectly passed, Exotel will look up if content matches Templates added on Exotel for fetching SMS Type and DLT details.
