If you run the demo code of Express Checkout client-side JS in Internet Explorer 11 it does not work and displays the error message "Can not render button in IE intranet mode". I have read through the developer documentation and blogs and it does not appear anyone has solved this issue for this specific example. I even ran the below demo code untouched with the same result. <!DOCTYPE html> <head> <meta http-equiv="X-UA-Compatible" content="IE=edge" /> <meta name="viewport" content="width=device-width, initial-scale=1"> <script src="https://www.paypalobjects.com/api/checkout.js"></script> </head> <body> <div id="paypal-button-container"></div> <script> paypal.Button.render({ env: 'sandbox', // sandbox | production // PayPal Client IDs - replace with your own // Create a PayPal app: https://developer.paypal.com/developer/applications/create client: { sandbox: 'AZDxjDScFpQtjWTOUtWKbyN_bDt4OgqaF4eYXlewfBP4-8aqX3PiV8e1GWU6liB2CUXlkA59kJXE7M6R', production: '<insert production client id>' }, // Show the buyer a 'Pay Now' button in the checkout flow commit: true, // payment() is called when the button is clicked payment: function(data, actions) { // Make a call to the REST api to create the payment return actions.payment.create({ payment: { transactions: [ { amount: { total: '0.01', currency: 'USD' } } ] } }); }, // onAuthorize() is called when the buyer approves the payment onAuthorize: function(data, actions) { // Make a call to the REST api to execute the payment return actions.payment.execute().then(function() { window.alert('Payment Complete!'); }); } }, '#paypal-button-container'); </script> </body>
