I can give you the steps on how to renew your Payments Token for your Merchant Payments account.
QuickBooks Payments will send an automated reminder 30 days prior to the token's expiration date. To refresh your tokens, click the Refresh icon on the email then sign in to the Merchant Services Center. Once you have completed this task, the message will not appear again until the next expiry date.
However, if you're getting this alert on your Quickbooks Point of Sale workstation, perform the steps below:
Go to the POS Home page .
Click the Payments icon at the top-right corner to sign in.
