Create a variable

Last updated Apr 16, 2026 Variables are reusable blocks of information. They allow you to have one source of data you can reuse across tools and triggers in the dashboard. You can then update this data in a single place.

For example, instead of typing a specific user ID in multiple fields, you can create a variable with that information instead. If there is a change and you have to update the user ID, you just need to update the variable and the change will be reflected across the dashboard.

Worker Variables are a special type of variable that generates value dynamically.

Create a new variable

  1. In the Cloudflare dashboard, go to the Tag setup page. Go to Tag setup ↗
  2. Go to Tools Configuration > Variables.
  3. Select Create variable, and give it a name.
  4. In Variable type select between String, Masked variable or Worker from the drop-down menu. Use Masked variable when you have a private value that you do not want to share, such as an API token.
  5. In Variable value enter the value of your variable.
  6. Select Save.

Your variable is now ready to be used with tools and triggers.
