PayPal Express Checkout for India
In India, you can add PayPal Express Checkout as an option in the payment method step during the checkout process. The PayPal integration supports purchases made in United States Dollars (USD).
Set up your account
To use the PayPal Express Checkout, you need to sign up for a new account with PayPal. If you don't have a PayPal account with the email address you used to set up your store, then you can add your email address to your existing PayPal account.
When you set up a new PayPal account you need to verify your business information, and complete the KYC procedure. If you have any questions about creating your account, then contact PayPal Customer Support.
If you want to issue refunds or manually capture payments using PayPal, then you need to give Shopify permissions from your PayPal account.
From your Shopify admin, go to Settings > Payment providers.
In the PayPal section, select your PayPal account type.
Enter the email address for your PayPal account, then click Next.
Enter the password for your PayPal account, then click Log In.
On the PayPal permissions page, click I Give Permission.
On the PayPal confirmation page, click Go back to Shopify.
Make a test transaction to make sure everything is set up properly.
