Google Chat code samples

This repository contains the code samples for Google Chat apps. There are folders of samples dependent on language and platform. Generally the Java and Python samples live in each respective directory, but JavaScript has multiple form factors (client-side, server-side/Node.js, Google Apps Script [also server side], and Cloud Functions [GCP or Firebase]).

Which JS platform you choose depends on the type of app application you're using/writing. Apps Script features tighter integration with Google Workspace data and applications, while Google Cloud Functions has a tighter integration with Google Cloud Platform services and APIs. Finally, mobile apps or mobile web apps are more likely to want to take advantage of Cloud Functions for Firebase. It is also generally straightforward to port from one JS implementation to another, for example, to Node.js.

In each folder, you can find a language-specific implementation of the one or more of the following code samples:

• Basic app: This app receives event notices and messages from Google
  Chat and responds synchronously with simple text responses. This sample
  demonstrates how to create an HTTP endpoint app using
  Google App Engine.
• Basic async app: This app receives event notices and messages from
  Google Chat and responds asynchronously with simple text responses. The
  responses will appear in the same thread that raised the original event or
  message. This sample is an HTTP endpoint app built upon
  Google App Engine.
• Pub/Sub app: This app uses
  Google Cloud Pub/Sub to receive messages
  from Google Chat. The app responds back to Google Chat asynchronously.
• Card app: This app receives event notices and messages from Google
  Chat and responds synchronously with a
  card-formatted
  response. This sample is an HTTP endpoint app built upon
  Google App Engine.
• Vote app: This app demonstrates updating interactive cards by providing
  a platform whereby users can vote on topics, such as who can do lunch today,
  who wants to play ball at lunch, etc. Samples can feature images or be
  text-only.

For additional details about how to set up and run each sample, consult the README file included with the sample.

Note: The Google Chat application, and the developer platform, are only available to Google Workspace accounts. You will not be able to develop or test a app with an @gmail.com account.
