# Create Checkout

**This endpoint is deprecated.**

Links a `checkoutId` to a `checkout_page_url` that customers are
directed to in order to provide their payment information using a
payment processing workflow hosted on connect.squareup.com.

NOTE: The Checkout API has been updated with new features.
For more information, see [Checkout API highlights](https://developer.squareup.com/docs/checkout-api#checkout-api-highlights).
We recommend that you use the new [CreatePaymentLink](../../doc/apis/checkout.md#create-payment-link) 
endpoint in place of this previously released endpoint.
