We have an smart home app with actions on google and already implemented the SYNC, QUERY and EXECUTE intents.
Now, we would like to implement the REQUEST_SYNC intent (mentionned in the fig. 2 here. However, we cannot find any documentation about it's implementation. Did anyone already implemented it?
Google updated their example Node.js code with request sync functionality: https://github.com/actions-on-google/actionssdk-smart-home-nodejs
Refer to the last commit. Maybe you can start here.
