I2SMS is a US messaging provider that has served large utility companies and financial institutions for over 10 years. Connect a long number or short code you have with I2SMS to send and receive SMS.

Before you start

You'll need a long number or short code with I2SMS, along with its channel hash and the username and password for your I2SMS account. Ask I2SMS for the channel hash if you don't have it.

Adding the channel

Go to Settings > Channels and click New Channel. I2SMS is under SMS & Voice, or you can type its name in the search box.

Then fill in the form:

Click Add Channel.

Finishing setup

Once the channel is added, its configuration page shows a message URL. In the I2SMS dashboard, create a DEFAULT keyword and set the message URL as its URL, so that messages sent to your number reach your workspace. Select POST HTTP Variables and check No URL Output.

You can come back to the message URL at any time from the channel's page.

Considerations

Messages are sent as plain text, and long messages are split into several. Any attachments are sent as links.
