• I’ve been trying to set up Postman for delivery through Gmail with OAuth 2.0. I go through the Wizard and get all the way through. When I go to “Grant Permission” by Google, I am taken to the screen where I click “Allow”. After I hit allow, I get the following error message: “Error : Could not get access token please check your app settings for more about this error.”

    I’ve tried using Google APi, and ports 587, 465 and 25. I’ve set and reset client secret and API.

    Here is my diagnostic reading:

  • @kfajans I was experiencing a similar issue and the solution was to momentaneously disable my caching plugin (w3 Total Cache) when granting permission.
