Variables allow you to add configurable, dynamic, and extendable values to your request in the Request pane.
In any supported field just type {, and the variable selector will show. If you continue to type, it will filter the available variable by fuzzy matching your search query. Either click or press ↵ to insert the variable. It will instantly appear in the request preview and in any executed requests.

Variables can opt into have an editable mode, where you can configure the variable instance which will change the output value. Once you’ve made the changes just tap “Save” and the value will be immediately updated.
If there is a variable that Beak doesn’t have, or is just specific to your workflow, you can use the Beak Extensions API to create your own. You can make standard or editable variable to fit your needs perfectly.
