Clickatell offers two-way SMS on long numbers and short codes, managed from its portal. Connect a number you've linked to a two-way SMS integration there, and contacts' replies come straight to your workspace.

Before you start

You'll need a Clickatell number linked to a two-way SMS integration, and that integration's API key. Clickatell explains two-way SMS and how to add SMS numbers in its portal.

Adding the channel

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

Then fill in the form:

Field	What to enter
Country	The country your number is in
Number	Your number, with its country code, or your short code
API Key	Your integration's API key

Click Add Channel.

Finishing setup

Once the channel is added, its configuration page shows two URLs to set on your integration in the Clickatell portal, so that messages and delivery updates reach your workspace:

• Reply Callback: set your integration's reply callback to HTTP POST, with this URL as its target address.
• Delivery Notifications: set your integration's delivery notification URL to HTTP POST, with this URL as its target address.

Leave the username and password for both blank. You can come back to these URLs 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.
