BEFORE YOU GET STARTED:
This code sample shows the new checkout flow called In-Context checkout experience. You need to meet the eligibility criteria to determine whether your integration will be a good candidate for In-Context checkout experience option. Please refer to the eligibility criteria .
If you are eligible for In-Context checkout based on the eligibility requirements, please refer to the 'In-Context Checkout integration steps' below. But, if you are not eligible, please refer to the 'Express Checkout integration steps' below.
PRE-READ:

1) Click on ‘Checkout with PayPal’ button and see the experience.
2) If you get any Firewall warning, add rule to the Firewall to allow incoming connections for your application.
3) Checkout with PayPal using a buyer sandbox account provided on this page. And you're done!
4) The sample code uses default sandbox REST App credentials which are set in paypalConfig.php. You can get your own REST app credentials by creating a REST app with the steps outlined here.
5) Make following changes in paypal_config.php:
- If using your own Sandbox seller account, update MERCHANT_ID with your merchant id. To get your merchant id, log into your Sandbox or Live business account as per the integration. The merchant ID can be found under My Account > Profile > My business info > Merchant account ID.
- Also, update SANDBOX_CLIENT_ID and SANDBOX_CLIENT_SECRET values with your REST app seller sandbox credentials
- SANDBOX_FLAG: Kept true for working with Sandbox, it will be false for live.
