Receiving an SMS via HTTP
The MX Telecom SMS Gateway can send SMS messages to your platform using HTTP. This page details the format that the HTTP requests take.
Your platform will need to accept HTTP GET method requests from the following IP address ranges:
- 18.104.22.168 - 22.214.171.124 (126.96.36.199/23)
- 188.8.131.52 - 184.108.40.206 (220.127.116.11/24)
- 18.104.22.168 - 22.214.171.124 (126.96.36.199/22)
For security, make sure that your platform only accepts requests from that IP range.
You will need to provide us with a URL to your platform. To protect the data while in transit, we recommend using an HTTPS (SSL) URL.
The SMS Gateway includes the following parameters in the HTTP GET request:
|smsfrom||The mobile number (MSISDN) that the message originates from.|
|smsto||The Short Code or Virtual Mobile Number that received the SMS message.|
|smsdate||The time and date that the SMS Gateway received the message, in the format: yyyy-MM-dd hh:mm:ss. This value is the current time and date in London, United Kingdom (either GMT or BST, depending on the time of year).|
|network||The originator's network. The SMS Gateway can
only determine this value for SMS messages sent to a Short Code. Click here
for a list of the network codes that the SMS Gateway passes for this parameter.
For SMS messages sent to a Virtual Mobile Number, the SMS Gateway sends the code UNKNOWN.
|smsid||A positive 64 bit integer used to uniquely identify the SMS message as it passes through the SMS Gateway. As well as when passing on a Mobile Originated SMS messages, the SMS Gateway will send SMS IDs with delivery reports and HTTP responses.|
|bits||Indicates the format of the SMS message body, as specified by the smsmsg parameter.|
|7||The message body is in the Latin-9 (ISO-8859-15) character set.|
|8||The message body is hexadecimal encoded data. This is commonly used when the message body is binary code.|
|16||The message body is in UCS-2 Unicode, and both the smsmsg and smsucs2 parameter specify the message body. The smsmsg parameter value is a best-effort 7-bit text representation of the UCS-2 Unicode data carried in the smsucs2 parameter.|
|smsmsg||The SMS message body. The format is indicated by the bits parameter.|
|smsudh||The UDH content sent with the SMS message. The SMS Gateway only sends this parameter when the SMS message contains UDH content.|
|smsucs2||This parameter is sent only when the message body is UCS-2 Unicode encoded messages. This parameter is hexadecimal encoded. Messages are commonly UCS-2 Unicode encoded when they contain special characters. The smsmsg parameter contains a best-effort text representation of this data.|
When sending HTTP GET requests we will attempt up to 10 message deliveries, until successful, with an exponential delay between sending (30 seconds, 60 seconds, 120 seconds etc).
It is the your responsibility to filter duplicate requests, using the smsid value. These might occur if for some reason we did not receive the HTTP response from a previous attempt within 60 secs (for example, due to packet loss over the Internet).https://server.com/drpt.cgi?
Response to the SMS Gateway
Your platform should respond with an HTTP 200 response with a non-empty body. This response must be given in a timely manner (within 10 seconds). Currently we do not abandon a request (waiting for the HTTP response) until 60 seconds have passed but this might be reduced in future.
