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.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/google-chat-integrations-for-workspace: open an issue to ask a question, or submit a pull request to add artifacts.
