This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.


This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

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.


function validatePayment(response) {
  const correctionPromises
  let paymentErrors = {};
  let payerErrors = {};

  // 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 ###-###-####."

  // Check everything else too...
