 * Hi [@nagarajawlts](https://wordpress.org/support/users/nagarajawlts/)
 * Thank you for providing a screenshot of the authentication error happening on
   your site for Square payments.
 * Looking at the error, it seems there’s a problem with the account connection:
 *     ```
       [category] => AUTHENTICATION_ERROR 
       [code] => UNAUTHORIZED
       ```
   
 * Please go to **WooCommerce > Integrations > Square** and disconnect your account.
   Then reconnect it.
 * Following this, try making a test purchase (you'll need to spend at least $1 
   to test, which you can refund afterwards).

 * Hi [@nagarajawlts](https://wordpress.org/support/users/nagarajawlts/)
 * Just wondering if there are any updates with this. Have you been able to get 
   everything working correctly with the Square payments?
