Web2SMS API Documentation

Quick Start

With our Web to SMS service, you can automate the sending of text messages from your website or devices. You'll need credit in your account to send messages.

The API documented below is our legacy API and has been in use for over 10 years. For new integrations, we recommend using our Connexus API. You can test API calls using our interactive OpenAPI documentation.

Note: SMS messages cost $0.10 +GST per message. Premium route with delivery reports costs an additional $0.02 +GST per message.

Delivery Reports (DLR)

When you specify a dlrurl, we'll send delivery status updates to your server via GET requests.

Example DLR Callbacks

GET /delivery-report.php?id=109720&dlr=8 - Message Queued
GET /delivery-report.php?id=109720&dlr=1 - Message Delivered

DLR Status Codes

DLR Code	Status	Description
`1`	Delivered	Message successfully delivered to handset
`2`	Failed	Delivery failure
`4`	Buffered	Message buffered for delivery
`8`	Queued	Message queued at SMSC
`16`	Rejected	Message rejected by SMSC

Note: Sometimes messages may be delivered but only show DLR 8 (Queued) due to SMSC resource prioritization.

Reply Messages

Reply messages are delivered to your registered email address and optionally to your DLR URL.

Reply Callback Example

Note the + prefix in the message ID for reply messages.
