Enable developers and engineers to send and receive SMS from the application of their choice with our easy to integrate SMS API. Receive inbound text messages along with delivery reports through the callback system. Popular functions include: creating lists, leasing numbers, setting up keywords, and scheduling messages.

Dedicated Servers

Performance and reliability is something we take very seriously. That’s why our flexible SMS API suite runs on it’s own dedicated server. Messages can be sent quickly since the SMS API servers do not share resources with the Bulk SMS Gateway.

Call Backs

Call Backs

The best way to get immediate notification on the events like SMS delivery or incoming messages is to set up callback URLs. We will call this URL immediately after the event occurs and, if the call was unsuccessful, we will retry a few times later.

DLR’s

DLR’s

DLR’s are Delivery Level Receipts, which are notifications received from carriers relating to the success or attempted SMS Delivery. Rather than having to poll for a message status, we will deliver DLR’s to your call back URL when we get them.

Short Codes

Numbers are the Caller ID, or from field that your messages will come from. Although not mandatory for SMS API use, we recommend users to lease their own Dedicated Shortcode to send and receive messages through the API.
