Use variables in Shortcuts on iPhone or iPad
In Shortcuts, you can:
Place a variable in a text field: For example, you can place a variable in the text field of an email shortcut, letting you choose a specific salutation (such as “Dear Sir” or “Dear Madam”) when you run the shortcut.
Use a variable to replace an action’s parameter (a setting inside an action): You can embed a variable in an action. For example, you can place an Ask Each Time variable in the Repeat parameter of a Play Music action, letting you choose whether or not to repeat a song when you run the shortcut.
Variables are represented by blue pill-shaped tokens.
Add a Magic Variable to an action

on the shortcut you want to modify, then tap any text field in an action.Note: Not all actions contain text fields.
The Variables bar and keyboard are displayed.
Tap Select Variable.
The shortcut editor displays an alternate view showing each action’s output as a Magic Variable (blue tokens underneath each action).
Tap the Magic Variable (the blue token under an action) that you want to add to the text field.
The variable is placed in-line in the text field (at the original insertion point). This is where the stored data will be placed when the shortcut is run.

The output of the previous action is stored in the variable.

Optional: To change the value of the variable, tap the last parameter and choose the content for the manual variable.
Manual variables should only be used when you need to hold a value that might change or when you need to add to a variable’s value. If you want to use static text or a number, use the Text action or Number action, then recall the Text or Number output later in the shortcut as a Magic Variable.

Replace a parameter with a variable
You can replace an action’s parameter (a setting inside an action) with a variable to dynamically switch between the settings of an action while a shortcut is running.
