Handle errors

These procedures apply to standard and advanced integrations.

Buyer checkout error

If an error prevents buyer checkout, alert the user that an error has occurred with the buttons using the onError callback:

paypal.Buttons({
  onError: function (err) {
    // For example, redirect to a specific error page
    window.location.href = "/your-error-page-here";
  }
}).render('#paypal-button-container');

This error handler is a catch-all. Errors at this point are not expected to be handled beyond showing a generic error message or page.
