Request parameters

Key Value
username API account user name from the Messente's web page
password API account security key (API key) from the Messente's web page
to Receiver's phone number with the country code

pin_length Length of the PIN code. Minumum 4 digits, maximum 16. Defaults to 4.
from Optional parameter that sets the Sender name.
When not set, the default Sender name "Verify" is used. This sender ID also needs to be added to your account beforehand.
max_tries Optional. Maximum number of times the PIN code is sent in total.
Defaults to "2" - initial PIN code and one retry.
It is discouraged to set this value to "1" as only the initial PIN code is sent and retry is disabled.
