适用于Google Assistant对话Webhook的Proto文件或类似文件？

Question

Google assistant has a json webhook api called the 'conversation webhook' (api documentation) and a node.js client library for it here .

Question: is there a .proto protobuffers file or some other single-source-of-truth file that I can use to help me get started writing a server for this webhook in a language other than node.js?

More info:

• in my case I'd like to handle the webhook in go (golang), but I expect others would want to create a webhook server for google assistant actions in python, java, etc.
• basically I'm looking for whatever google uses as the single source of truth for this api. I assume the online documentation (see first link above) is auto-generated from a file and not written by hand.
• I'm really hoping there's a .proto file that is or can be made available so that go/python/java/etc. client libraries can be (somewhat) auto-generated. Lots of google's public api's have this available, see github.com/googleapis . The new assistant sdk for embedding the assistant in a device also has a proto file for it's interface definition, see assistant/embedded at github.com/google-apis .

Thanks in advance for any help.

PS: if a proto file isn't available and there are googlers reading this, please can you try to make one available! I could list the many benefits of having one available to the community, but then I'd be stupidly trying to sell protobuffers to googlers! So I'll leave it there. Thanks.

I couldn't find anything provided by google which authoritatively showed the request/response flow for conversation actions. I used a couple implementations I found on GitHub to get my python app working. I found Github - actions-on-google-php and Github - google-action-three-doors helpful in showing the JSON passed back and forth in the protocol.
