# Autofill customer details

You can automatically fill in certain details in the Checkout Session payment form by using the **Customer Email** or **Stripe** **Customer ID** fields that come with the 'Create Checkout Session' actions.

For example, you can add the Current User's email to the **Customer Email** field:

The users email will then be autofilled in the Checkout Session:

Once your customer has made a purchase via Stripe, you will be able to save down their Stripe Customer ID and use this in the **Stripe Customer ID** field:

This means the customers payment details will be autofilled too:
