Authentication token expired

Question

We're using API V13 of the Bing Ads API.

It was working fine and then without us touching our code, we started to get "AuthenticationTokenExpired" errors.

We checked an re-checked many times and our authentication token is created right before making a call, so it can't have expired in a few seconds. What's going on?

Below is the exception we're getting:

 [previous:Exception:private] => 
    [faultstring] => Invalid client data. Check the SOAP fault details for more information. TrackingId: 4621e7a3-5add-456f-800d-45aab387f34e.
    [faultcode] => s:Server
    [faultcodens] => 
    [faultactor] => 
    [detail] => stdClass Object
        (
            [AdApiFaultDetail] => stdClass Object
                (
                    [TrackingId] => 4621e7a3-5add-456f-800d-45aab387f34e
                    [Errors] => stdClass Object
                        (
                            [AdApiError] => stdClass Object
                                (
                                    [Code] => 109
                                    [Detail] => 
                                    [ErrorCode] => AuthenticationTokenExpired
                                    [Message] => Authentication token expired. Please renew it or obtain a new token.
                                )

                        )

                )

        )

Answer 1

We were able to resolve our issue by changing the requested scope to "openid offline_access https://ads.microsoft.com/msads.manage" in the OAuth authorization request that redirects the user to https://login.live.com/oauth20_authorize.srf.

Then when requesting the access token we added the scope "https://ads.microsoft.com/msads.manage" in the request. It does require the user to create a new OAuth authorization, but seems to have resolved it on our side.

Answer 2

Same issue here. Started happening on May 6th and all request are being returned with a "AuthenticationTokenExpired" after successfully retrieving a new token. Recreating the application is not an option for us due to the amount of customers registered on the current application.

Answer 3

Guess don't have much to add at this point apart from mentioning that we've been observing same issue since 05/05.

Answer 4

We are also facing the same issue from may 5th 2023. Tried the refresh token generation too many times still the same error .

AdApiError = 
      (AdApiError){
         Code = "109"
         Detail = None
         ErrorCode = "AuthenticationTokenExpired"
         Message = "Authentication token expired. Please renew it or obtain a new token."
      }
