Our SMS API, simply, easy


This page provides a reference for all features available to you via the HTTP interface for sending SMS.
The HTTP-API allows you to integrate your system (client) to Easy Send SMS using the HTTP protocol to send SMS. HTTPS is also supported for secure transactions using SSL encryption.
The Client issues either a HTTP GET or POST request to the Easy Send SMSHTTP interface supplying a list of required parameters. Our system issues back a HTTP response which indicates the status of the sent message.
The HTTP-API is used for one-way messaging only. Therefore, you need to provide a valid the Sender ID of the message to enable the recipient to respond.

userYour Easy Send SMS usernameMandatory
passwordYour Easy Send SMS passwordMandatory
fromSender Name that the message will appear from.

 Max Length of 18 if numeric.
 Max Length of 11 if alphanumeric.
To prefix the plus sign (+) to the sender’s address when the message is displayed on their cell phone, please prefix the plus sign to your sender’s address while submitting the message (note the plus sign should be URL encoded). Additional restrictions on this field may be enforced by the SMSC.
toMSIDSN of the recipient that the message will be sent to. Eg: 61409317436 (Do not use + before the country code)Mandatory
textThe message to be sent. It can be used for 'long' messages, that is, messages longer than 160 characters for plain text, 140 for flash and 280 for Unicode. For concatenated (long) messages every 153 characters are counted as one message for plain text and 268 characters for Unicode, as the rest of the characters will be used by the system for packing extra information for re-assembling the message on the cell phoneMandatory
TypeIt indicates the type of message. Values for type include:

0: Plain text (GSM 3.38 Character encoding)
1: Unicode
2: Flash (GSM 3.38 Character encoding)
3: Unicode Flash

All rights reserved 4 Request Parameters characters are counted as one message for plain text and 268 characters for Unicode, as the rest of the characters will be used by the system for packing extra information for re-assembling the message on the cell phone. )


HTTP Response

The HTTP response from our system contains the following:

  • Status Code
  • Sent OK Message ID (Internal use only)
  • SMS ID
  • Error message (if present)


Status Codes

If the message has been sent successfully the status code will return OK: 0



If the message was unable to be delivered it will return ERROR: {Error code}





Below are example requests when using the HTTP interface.


Example Send Single SMS (English)

Username: testuser

Password: secret

From: Test

To: 103333333333

Text: Hello World

Type: 0




Example Send To Multi Numbers ( Bulk SMS )


A request containing multiple destinations will be aborted immediately if any error other than “Invalid Destination” is found. In case an invalid destination is found we just skip that destination and proceed to the next destination, maximum you can send 30 numbers per submission


Example Send Single SMS ( Unicode )


calling the above link by replacing the username and password by your account credentials, you should get the SMS ‘easysendsms.com’ on the mobile number in the destination field. The message has to be encoded on the UTF-16BE format and the type parameter has to be set to (type=1).


Status Codes


delivrdThe message has been received by the handset.
expiredThe carrier has timed out.
undelivThe messages failed to reach the handset.


Information on Unicode

Error Codes


1001Invalid URL. This means that one of the parameters was not provided or left blank.
1002Invalid username or password parameter.
1003Invalid type parameter.
1004Invalid message.
1005Invalid mobile number.
1006Invalid sender name.
1007Insufficient credit.
1008Internal error (do NOT re-submit the same message again).
1009Service not available (do NOT re-submit the same message again).
