How can I disable the PayPal Credit button?

I know this is kind of an old question, but I just spent an hour trying to find the answer to this, so hopefully this helps someone someday.

If you're using the new integration method that starts paypal.Buttons instead of paypal.Button.render, you have to append disable-funding to the JS SDK.

<script src="https://paypal.com/sdk/js?client-id=YOUR_CLIENT_ID&disable-funding=credit,card"></script>

card = Credit or debit cards

credit = PayPal Credit

sepa = SEPA-Lastschrift

Source: https://developer.paypal.com/docs/checkout/reference/customize-sdk/#disable-funding

If your the webmaster and you have access to the PayPal account login where the PayPal button was created click on merchant tools and edit your saved PayPal buttons there is an option to remove the credit card area. https://www.paypal.com/buttons/

What I did was to put a div over the Paypal button, then disable the div when needed:

NORMAL PAYPAL BUTTON RENDERING:

  paypal.Button.render({

    // Set your environment
    env: 'production', // sandbox | production

    // Specify the style of the button
    style: {
        label: 'pay',   // paypal | checkout | pay
        size:  'small',    // small | medium | large | responsive
        shape: 'pill',     // pill | rect
        color: 'gold',      // gold | blue | silver | black
        tagline: 'true'
    },

    // PayPal Client IDs - replace with your own
    // Create a PayPal app: https://developer.paypal.com/developer/applications/create
    client: {
        sandbox:    'XXX',
        production: 'YYY'
    },

    payment: function(data, actions) {
        return actions.payment.create({
            payment: {
                transactions: [
                    {
                        amount: { total: totalAmount, currency: 'USD' }
                    }
                ]
            }
        });
    },

    onAuthorize: function(data, actions) {
        return actions.payment.execute().then(function() {
          window.alert('Payment Complete!');                                 
        });
    }

  }, '#paypal-button-container');

ADDITIONAL STUFF POST BUTTON RENDER:

  $("<div id='paypal-fake-cover' onclick='removeCover();' />").css({
    cursor:"pointer",
    position: "absolute",
    width: "100%",
    height: "100%",
    left: 0,
    top: 0,
    zIndex: 1000000,  // to be on the safe side
  }).appendTo($("#paypal-button-container").css("position", "relative"));

REMOVE COVER:

function removeCover(){
  $('#paypal-fake-cover').remove();
}
