Once you say the keyword for a third-party action, you’ll start talking to that company’s bot instead of Google’s.Making a decent conversational bot is hard, so Google is suggesting services like its own API.It also needs to enable more complicated actions like buying and booking stuff.
The actions will let you ask the speaker a question and then have a chat about it — the example Google gave in October was ordering an Uber, then clarifying you want an Uber XL.
That whole conversation actually be with the Google assistant, though.
“It's not a direct analog to any existing ecosystem,” says Jason Douglas, director for actions on Google.
There will be app store-like policies in place to prevent things like keyword camping — one developer using another company’s name for their action or another developer trying to jump on owning important keywords like “shopping.” Douglas says that “this is a large reason for there being a review process.
Direct actions — things that don’t require a conversation, such as turning on your lights or playing a song — still require a partnership with Google.
