What makes our SMS API suite epic?
Deploy SMS fast with our quick start API docs. Perfect for developers new to SMS, or for advanced users looking for extensive features.
Trigger alerts for an SMS delivery or incoming messages with HTTP callbacks. These URLs will be notified immediately after an event occurs.
Delivery Level Reports
Generate delivery level reports with a single send-sms call. Your DLR callback is the default URL we post incoming DLR’s to.
We limit the number of SMS API calls which can be made by each account to 2 calls per sec. For heavy users we can increase your throttling speed.
