This document provides a reference for all features available to you via the HTTP interface for sending SMS.
The HTTP-API allows you to integrate your application (client) to SMSGlobal (vendor) 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 SMSGlobal HTTP interface supplying a list of required parameters. SMSGlobal issues back a HTTP response which indicates the validity of the transaction.
The HTTP-API is used for one-way messaging only. Therefore, you need to provide a valid MSISDN as the Sender ID of the message to enable the recipient to respond.
HTTP API Features
- Custom Sender ID
- Dedicated Virtual Numbers
- Delivery Receipt Notifications via Email/SMS
- Recipient OPT Out Option
- 24/7 support via our support team

Incoming SMS HTTP Post Back
If you would like notifications of Incoming SMS messages to be pushed to your server, please ensure you specify a URL in your account settings.
In order for our system to know that your URL has received the delivery notice, at the end of your script you must echo out “OK”. The post back response time is restricted to five seconds. If the specified URL does not return ‘OK’ within five seconds of being sent, the request will be marked as incomplete and the process will be repeated.
Please find below the list of parameters that are sent.
| Parameter | Description |
|---|---|
| to | Mobile Terminated Number, where the message was sent to |
| from | Mobile Originated Number, where the message was sent from |
| msg | Contents of the message |
| userfield | Unique userfield passed in the original request |
| date | Date the message was received by SMSGlobal. |
Important Information If You Have Dedicated Numbers
Often it is practical to have all SMS traffic sent from the same number each time. This makes it easier for recipients to reply to your message and to send message campaigns.
A dedicated number works like a normal mobile number. Once you have purchased one you will be able to receive text messages to it as you would a regular mobile number. Friends, customers or anybody with a mobile will be able to send SMS text messages to you via this number.
Note: When you start using 2 way SMS and dedicated numbers, the userfield no longer works and is ignored on the API.
