Pre-Populate SMS Messages With Links in GoHighLevel
By Marnix Geerkens. Published 2021-01-26. Updated 2026-06-02.
You can craft a URL that opens a phone's SMS app with a phone number and message body already filled in. Link it from a button on a landing page or funnel step, and the visitor just taps send. When the message arrives in GoHighLevel you can trigger automations based on what it says, such as running different campaigns for different offer codes.

Summary. This tutorial covers the technique of pre-populating an SMS message body using a specially formatted link. By placing this link on a webpage button, clicking it opens the native SMS app on a mobile device with the recipient number and message text already written. The message that arrives in GoHighLevel can then be matched by a workflow trigger looking for a specific phrase or code.
