What is an SMS API?
An SMS API lets your website, app or server send text messages automatically. Your code sends a request with the number and message, and the SMS gateway delivers it to the mobile operator.
The Amar SMS API works for every message type: masking, non-masking and OTP. Bangla Unicode is detected automatically and long messages are split for you.
