Shift4 AuthToken, AccessToken, AccessBlock

With Shift4, there are 3 sometimes confusing terms referring to items that are used for security and authentication. Most confusion is related to the Auth Token and the Access Token. It's not uncommon for both us and Shift4 to mistakenly use the wrong term, so verifying is a critical step and will avoid hours of unnecessary troubleshooting.

Auth Token

  • The Auth Token is typically provided to us by Shift4 or the customer.
  • It is used to generate the Access Token.
  • *Transactions DO NOT use the Auth Token. It's only used a single time to obtain the Access Token. It expires once it's used, and is often only valid for a limited time and must be used within this time.

Access Token

  • The Access Token should be entered into MENUS4CO, the Shift4 configuration tool in the Execu/Tech software.
  • If you received an Access Token rather than an Auth Token: In the Merchant ID tab of MENUS4CO, enter it into the Access Token field.
  • If you received an Auth Token: In the Merchant ID tab of MENUS4CO, right-click the Access Token field and enter the Auth Token into the prompt that appears, then click OK.

    *If the PMS version the customer has doesn't allow you to generate the Access Token, either Shift4 or the customer can generate it using the UTG. Ask them to do this and provide you with it.

Access Block

  • The Access Block is only used with i4Go V2.
  • Using the Access Token, temporary permission is granted to process a transaction, and the Access Block is part of the security measure used to authenticate you.
