Variables

Variables are placeholders for content that you can then use anywhere in the Typebot. It's a very important concept to understand to truly create a customized experience for the user.

Save an answer in a variable​

You can tell your input step to save the answer into a variable and reuse then in a further bubble for example:

Advanced concepts​

Here is a quick video that showcase advanced concepts about variables:

Prefilled variables​

By default, any declared variables in the bot can be prefilled by passing initial values in the URL.

Let's say I have a variable named "Email" somewhere in my bot. If I'm launching my bot using this URL:

https://typebot.io/my-bot?Email=test@test.com

Then if an input step is saving the answer into this variable, it will be first prefilled with this initial value. It can greatly improve the user experience if you already have data about him.

Prefilling variables using the embed library is even easier. You need to add an object named hiddenVariables that contains a dictionary of your values. For example:

Typebot.initBubble({
  url: `https://viewer.typebot.io/typebot-support`,
  hiddenVariables: {
    'User ID': '123',
    'First name': 'John',
    Email: 'test@test.com',
  },
})

Hidden variables​

These are simply variables that are declared in the bot flow but aren't displayed to the user anywhere. This allows you to add some context to a session for example a User ID, a utm_source parameter (in the case of a marketing campaign), or anything else.

These can be simply declared with "Set variable" steps:

Then the values will be available on the Results page in specific columns:
