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 8 API contracts indexed on the APIs.io network, including Google Chat API, Members API, Message API, and 5 more. Tagged areas include Google Workspace, Team Chat, Messaging, Collaboration, and Chat Apps.

The Google Chat Integrations for Workspace catalog on APIs.io includes 1 Spectral governance ruleset.

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

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
