Google adds comment and suggested-edit support to Workspace APIs

Google has added API support for creating, reading and managing comments in Docs, Sheets and Slides, giving developers programmatic access to review activity in all three Workspace editors. In Docs, the release also lets API clients submit suggested edits, so automated systems can propose revisions for people to assess instead of changing document text directly. Google says the additions are intended to connect its editors with internal review tools, automated content pipelines and project-tracking systems. The change provides API access both to comments and, in Docs, to suggested revisions.

In Docs, developers can add comments, review them, respond to them and submit proposed text changes as suggestions. The Sheets API supports comments tied to particular cells, with the same add, review and reply operations. In Slides, comments can be associated with a slide or a specific presentation element, and developers can add, review and reply to them. The APIs thus support comments attached to different parts of documents, spreadsheets and presentations. For builders connecting review or project-tracking workflows, Google says the additions allow those systems to connect directly to Workspace editors.

Google says the rollout for Rapid Release and Scheduled Release domains will be gradual, with feature visibility taking up to 15 days after it starts on September 30, 2026. The release notice distinguishes the editor APIs from comment support in the Docs, Sheets and Slides Model Context Protocol (MCP) servers, which remains in developer preview. Google says that preview status aligns with the preview status of the MCP servers.

The new functionality is available to all Google Workspace customers and people using personal Google accounts. Google says there is no administrator control or end-user setting for the feature itself. Administrators can still control which apps access Workspace data, while users can manage links between their Google Account and apps from other developers. For AI builders, the update provides documented ways to route comments and proposed Docs revisions through software workflows, while keeping suggested changes for user review rather than applying them directly.
