# Create an access token for Checkout SDK features

`POST /v2.01/oauth/token/embedded/checkout`

Generate an access token to initialize the [Checkout SDK](/sdks/checkout/web) to offer PayPal One-Click.

The access token returned by this endpoint 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.
