This User Manual is for the developers and clients who want to integrate their systems with our Bulk SMS service. The manual contains all the necessary API specifications required for automated SMS sending via the Internet.
Our API requires an Internet enabled system. The Internet connection may be established:
This server-based mode of communication is extremely simple. In case of large data transfer and data security requirements, we recommend HTTP POST form, however, both HTTP POST and HTTP GET forms can be used for the service. URL encoding of all calls to the API is a must and care must be taken that parameter names are case sensitive.
Every text message has a sender ID. Any text message sent through API should be sent via a sender ID approved for your account. In case you need a new sender ID, please connect with us and we would be happy to help you.
Setting a Sender ID (Alphabetic Originator)
Enjoy the flexibility of setting the sender ID based on your company name, or any other parameter relevant to you. Your chosen name will reflect as the sender to the recipients instead of a phone number. You may choose a sender ID containing alphabets only.
A message sent via this service can be written using the standard SMS mobile-phone character set. 160 characters including few of the Roman alphabet, certain special character, the most common accented forms, and few Greek alphabets are allowed in the character set.
The following characters are included:
@ £ \ $ ¥ è é ù ì ò Ç \ n Ø ø \ r Å å
? _ F " ? O ? ? S T ? Æ æ ß É ! \ " # ¤ % & ' ( ) * + , - ../ 0 1 2 3 4 5 6 7 8 9 : ; <=> ? ¡ A B C D E F
G H I J K L M N O P Q R S T U V W X Y Z ? Ö Ñ Ü § ¿ a b c d e f g h I j k l m n o p q r s t u v w x y z
ö ñ ü à ä Ä { } \ ~ [ ]
Note: In case of extended characters, they will be treated as two characters to send. Extended characters are: £ ¥ è é ù ì ò Ç Ø ø Å å Δ Φ Γ Λ Ω Π Ψ Σ Θ Ξ Æ æ ß É ¤ ¡ Ä Ö Ñ Ü § ¿ ä ö ñ ü à | \ { } ~ [ ] ^ In case of the extended character €, three characters will be consumed.
In case of non-GSM 03.38 characters, the SMS is transmitted as a Unicode message. The Unicode character support allows messages to be sent in multiple languages such as Hindi and regional languages like Kannada, Tamil etc.
Transmission of Unicode messages costs double even when sent in plain English. If you choose the Unicode format, the entire message will have to be sent as a Unicode message.
Unicode messaging allows a maximum of 70 characters per SMS. If you wish to send longer messages, our system will split them into two or three separate text messages. In this case, the maximum lengths of two-part and three-part multipart Unicode text messages will be 134 (2 x 67) and 201 (3 x 67) characters, respectively. You can send maximum 8 multi-part messages with character limit of maximum 500 characters.
