Google Chat Integrations for Workspace

Google Chat is the messaging and collaboration platform built into Google Workspace, allowing teams to chat in direct messages, group conversations, and spaces with threaded discussions, file sharing, tasks, and Chat app integrations. The Google Chat REST API lets developers build Chat apps that send messages, manage spaces and members, post cards, handle slash commands, react to events, and integrate external services into Workspace conversations. Authentication uses OAuth 2.0 (user credentials for user-impersonating calls) or service-account credentials for app-bot calls.

Google Chat Integrations for Workspace publishes 7 APIs on the APIs.io network, including CustomEmojis API, Google Chat API API, Members API, and 4 more. Tagged areas include Google Workspace, Team Chat, Messaging, Collaboration, and Chat Apps.

Google Chat Integrations for Workspace’s developer surface includes authentication, documentation, pricing, signup flow, support, engineering blog, and 8 more developer resources.
