Use variables in requests
A variable is a fixed value that you save in your Data Fetcher workspace.
You can use variables in your requests, e.g. in a request URL or header. For example, you might save an API key as a variable and use it in multiple request headers. By saving it as a variable, you will only need to update it in one place if the API key changes.
- Hover over the extension, then clickto open the settings screen.

- Under Workspaces, click "Manage" next to the workspace you want to create the variable in.
- Under Variables, click "+ Add".
- Enter the variable name and value.
- Click "Save".

- Click the "+" button on the right-hand side of the input. Any input with a "+" button can use variables.
- On the modal, click "Variable" to switch to the variables tab.
- Select the variable you want to use.
- The input will now have a reference to the variable, which looks like:
-*-currency-*-
. When the request runs, this will be replaced by the variable value.
