To accept PayPal as a payment method, PayPal requires us to pass along a user's Merchant ID.
You can add your PayPal Merchant ID to your account settings for future transactions.
Where Can I Find My PayPal Merchant ID?
You can find your Merchant ID under your PayPal Account Settings.
Don't Have a Merchant ID?
If you don’t see a Merchant ID in your account settings, you may need to upgrade your PayPal to a Business Account, as per PayPal’s requirements.
If you do not wish to upgrade your account, we strongly encourage you to use our secure Express Checkout option instead. However, if you still want to accept PayPal, you will need to use the following workaround to obtain your Merchant ID. These instructions have been provided to us by PayPal.
