## Create a Radar session

`stripe.createRadarSession()`

Use `stripe.createRadarSession()` to associate client browser information with a Radar Session ID. This ID can then be passed to Stripe when [creating charges and payment methods](https://docs.stripe.com/radar/radar-session.md) to associate client browser information with those charges and improve Radar's ability to identify fraud.

We've prefilled the example with a sample [test API key](https://docs.stripe.com/keys.md). Don’t submit any personally identifiable information in requests made with this key.
To create a Stripe object using your account, replace the sample API key with your actual API key or [sign in](https://docs.stripe.com/login.md?redirect=%2Fdocs%2Fjs%2Finitializing).

> Note that `stripe.createRadarSession` should be non-blocking. If you receive an error from this function, continue on with completing charges without passing through a Radar Session ID.
