# Create an access token for Checkout SDK features

> Generate an access token to initialize the Checkout SDK to provide PayPal One-Click

This endpoint allows you to obtain an access token that you can use to initialize [Checkout SDK](/sdks/checkout/web).

This access token is only required for the following features using Checkout SDK:

* [PayPal One-Click](/sdks/checkout/web#configuring-paypal-one-click-payments)

You do not need an access token if using Checkout SDK to service other payment methods or PayPal without PayPal One-Click.

A single access token can be used to service the experience to one user and has a lifespan of 15 minutes. You need to provide the `UserId` of the Natural User or Legal User who will use the Checkout session to make the payment.
