You can prefill the bot variable values in your embed code by adding the `prefilledVariables` option. Here is an example:
```tsx
import { Standard } from '@typebot.io/react'
const App = () => {
return (
<Standard
typebot="lead-generation-copy-3luzm6b"
style={{ width: '100%', height: '600px' }}
prefilledVariables={{
'Current URL': 'https://my-site/account',
'User name': 'John Doe',
}}
/>
)
}
```
It will prefill the `Current URL` variable with "https://my-site/account" and the `User name` variable with "John Doe". More info about variables: [here](/editor/variables).
Note that if your site URL contains query params (i.e. https://typebot.io?User%20name=John%20Doe), the variables will automatically be injected to the typebot. So you don't need to manually transfer query params to the bot embed configuration.
