With our old PayPal Checkout integration, the only information you needed to provide in order to enable this payment integration was client ID and language.
With our new PayPal Checkout integration, we are requested to have in its setup some additional information, Merchant ID and email address. Without these 2 pieces of information, any PayPal Checkout integration that is already enabled would break.
Note: if you have a PayPal Checkout integration enabled on your form that does not have these 2 pieces of information (Merchant ID and email address), your payment integration will break and you will no longer be able to collect payments. It is mandatory for you to provide this information in order to make sure your form works flawlessly.
According to PayPal’s documentation, all you have to do is to log in to your PayPal account and go to Account settings.
Under Business profile, click on Business information. You’ll find your ID next to PayPal Merchant ID. Copy this value and paste it in your 123FormBuilder’s form, under Merchant ID field in your PayPal Checkout settings.
