API Sample

Send Bulk SMS

Note : If you submit large number of request, always use XML API for better performance.
Get http://sms.asaptech.net/api/sendhttp.php?authkey=YourAuthKey&mobiles=9999999999,919999999999&message=message&sender=senderid&route=1
Parameter Name Data Type Description
authkey * Alphanumeric Login Authentication Key(This key is unique for every user)
mobiles * Integer Mobile number can be entered with country code or without country code Multiple mobile no. should be separated by comma
message * Varchar Message Content to send
sender * Varchar Receiver will see this as sender's ID
route * Varchar If your operator supports multiple routes then give one route name
flash Integer (0/1) flash=1 (for Flash SMS)
unicode Integer (0/1) Unicode=1 (for Unicode SMS)
ignoreNdnc 1 ignoreNdnc=1 (if you want system to ignore all NDNC Numbers)
schtime Date and time when you want to schedule the SMS to be sent. Time format will be Y-m-d h:i:s
response varchar By default you will get response in string format but you want to receive in other format (json,xml) then set this parameter. for example: &response=json or &response=xml
campaign varchar campaign name you wish to create.

Parameters with (*) are mandatory.

Sample Output
5134842646923e183d000075

Note : Output will be request Id which is alphanumeric and contains 24 character like mentioned above. With this request Id, delivery Report can be Viewed. If Request not Sent Successfully, you will get the appropriate Error Message.

Encode Your Api

What is Url Encoding?

URL encoding converts characters into a format that can be send through internet We should use urlencode for all GET parameters because POST parameters are automatically encoded.

Why Url Encoding?

URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format.URLs use some characters for special use in defining their syntax,when these characters are not used in their special role inside a URL, they need to be encoded.Url encoding is done to encode user input

Example:

Get http://sms.asaptech.net/api/sendhttp.php?authkey=YourAuthKey&mobiles=9999999999&message=test & new&mobile&sender=123456&route=default

In this api the message content "test & new" includes '&' operator,due to which url encoding is necessary, otherwise it will break your message content and an incomplete message will be sent


Encoded Api

Get http://sms.asaptech.net/api/sendhttp.php?authkey=YourAuthKey&mobiles=9999999999&message=test+%26+new&mobile&sender=123456&route=default

By encoding message content in api,complete message will be sent

Send message on multiple numbers

Get http://sms.asaptech.net/api/sendhttp.php?authkey=YourAuthKey&mobiles=9999999999,919999999999&message=test+%26+new&sender=123456

To send message on multiple numbers numbers should be comma separated

Send unicode message

Get http://sms.asaptech.net/api/sendhttp.php?authkey=YourAuthKey&mobiles=9999999999,919999999999&message=test+%26+new&sender=123456&unicode=1

To send Unicode message one more parameter will be added i.e unicode and it's value will be set to 1

Send Flash message

Get http://sms.asaptech.net/api/sendhttp.php?authkey=YourAuthKey&mobiles=9999999999,919999999999&message=test+%26+new&sender=123456&flash=1

To send Flash message one more parameter will be added i.e flash and it's value will be set to 1

json response

Get http://sms.asaptech.net/api/sendhttp.php?authkey=YourAuthKey&mobiles=9999999999,919999999999&message=test+%26+new&sender=123456&response=json

To get response in json format one more parameter will be added i.e response and it's value will be set to json

Send Schedule message

Get http://sms.asaptech.net/api/sendhttp.php?authkey=YourAuthKey&mobiles=9999999999,919999999999&message=test+%26+new&sender=123456&schtime=2014-09-30 19:23:40

To schedule message i.e for future , one parameter will be added i.e schtime and it's value should be equal to that date and time,at which message should be sent. Note: for Scheduling, date and time are mandatory.
