acions on google smart home app not calling fullfilment

Question

I am trying to make an actions on google smart home app. I have implemented my oAuth2.0 server which seems to work fine. It generates an authorization token and sends it to Google with the state parameter provided by Google. However, when I try to do the account linking in my google home app, it fails with the default couldn't update the setting error. When I check my Firebase console, it says my smartHome function - the smart home fulfillment I provided in the actions on Google console - was never called, even though the other functions completed successfully.

What is the cause/solution for this?

Can you also provide some code? Where you ask for a sign-in, where you reveice the SIGN_IN_SUCCESSFUL event... — Rémi C., Jun 27 '18 at 07:04
@RémiC. Isn't that only if i am using something like dialogflow. the sign in is completely on my server. — Muaaz Kasker, Jun 28 '18 at 21:29
@NickFelker the code to create and exchange tokens runs without error. however in the google home app in the account linking page, it says : `couldn't update the setting. try checking your connection` — Muaaz Kasker, Jun 28 '18 at 21:31
@NickFelker even though the fullfilment is never called, do you want a snippet of that code? — Muaaz Kasker, Jun 30 '18 at 18:16

The Smart Home fulfillment is never called for your action because apparently your OAuth flow is not correctly set up. Please visit this link and make sure that everything is set up according to the authorization code flow.

Furthermore, Test Suite can also be used to validate the account linking implementation: https://developers.google.com/assistant/smarthome/tools/smart-home-test-suite#account_linking_validation_test
