The name property is included in a PayerErrors object if the payerName returned in the response couldn't be validated. The value is a string explaining the problem. If the payer's name validated successfully, the name property is omitted from the PayerErrors object.


payerName =;


If this property is present in the PayerErrors object, the payer's name couldn't be successfully validated, and the name property's value is a DOMString explaining the error. This string will be displayed to the user by the user agent's payment handling user interface.

If the payer's name is valid, this property is left out of the PayerErrors object.

  const correctionPromises
  let paymentErrors = {};

  // Check payer details

  if (!validEmail(response.payerEmail)) { = "Please make sure you enter a valid email address."
  if (!validName(response.payerName)) { = "Please enter a valid name, using only <appropriate characters>."
  if (!validPhone(response.payerPhone)) { = "Please enter a valid phone number in the form ###-###-####."
