# Input variables

### Creating Input Variables

Input variables allow you to set variables that may change between runs. You can access them by opening a flow's settings:

![](/files/4HGEZWbbLVlT5wrMklTb)

For example, if you create a flow that scrapes all the tweets from a particular profile, you can create an input variable for the username so that it can be changed between runs.

![](/files/TXJJXVrErgpJY8VVSR8A)

The "Clear value when flow is shared" option ensures that any sensitive information will be removed when you share a flow.

Once you've created an input variable, you can reference it in your flow to customize the behavior:

![](/files/HssAoYYusOoq6mS3tcf9)

### Using Input Variables

Once created, input variables allow you to easily change variables between runs by setting values in the Run tab:

![](/files/IJrW9tskJVOwalRtpkXV)
