As mentioned by google: https://developers.googleblog.com/2022/02/making-oauth-flows-safer.html

Certain OAuth Methods are getting deprecated by October. This impacts the OOB flow as highlighted:

OAuth out-of-band (OOB) is a legacy flow developed to support native clients which do not have a redirect URI like web apps to accept the credentials after a user approves an OAuth consent request. The OOB flow poses a remote phishing risk and clients must migrate to an alternative method to protect against this vulnerability. New clients will be unable to use this flow starting on Feb 28, 2022.

Software Design / Architecture

Since we are currently using OOB authentication for all google related products, we enhanced our authentication feature oaut2Token as follows:

  • The Google API client has been updated.

  • The OAUTH2.0 authentication (without the use of OOB, as described here) has been implemented.

  • A new redirection system has been implemented by using our own callback URL.

Subject line: Critical Update: Google OAuth

 

Hi $name$

 

ADvendio is planning to make a major system update in order to use Google integrations. This is followed by Google's decision to deprecate some of its OAuth methods and to make future third-party sign-ins more secure. 

 

This update will be automatically included in ADvendio version 2.158 so it is crucial to update ADvendio systems to this version by October 3rd, 2022. These changes will impact our customers who are using GAM/DFP, DV360, and GCM360 Google integrations.

 

Once the 2.158 version is installed, it is important to refresh a token. Without this token, Google Connections would not be working (e.g. features like Submit of Items & Delivery Reports). 

Please see the steps on how to refresh the token:

Please reach out to us urgently if you have any issues or concerns regarding the update to version 2.158.
