In Docs, the update also adds API support for suggested edits, so automated tools can propose document revisions for a person to review rather than changing the content directly.\n\nThe announcement was posted on the Google Workspace Updates blog on September 30, 2026. Google describes the purpose as letting organizations connect internal review tools, automated content pipelines and project-tracking systems directly to Workspace editors.\n\nThe capabilities differ by product. According to Google, the Docs API lets developers add, review and reply to comments and submit proposed text changes as suggestions. The Sheets API covers adding, reviewing and replying to comments on specific cells. The Slides API covers the same comment actions for individual slides and specific presentation elements. Suggested edits are listed only for Docs.\n\nOne related feature is not yet generally available. Google says programmatic comment support in the Docs, Sheets and Slides Model Context Protocol (MCP) servers remains in developer preview, in line with the preview status of those servers.\n\nOn availability, Google says the rollout to Rapid Release and Scheduled Release domains is gradual, with up to 15 days for the feature to become visible starting September 30, 2026. It says the features are available to all Google Workspace customers and to users with personal Google accounts.\n\nGoogle says there is no admin control or end-user setting for the feature itself. Admins can still control which apps can access Workspace data, and users can manage links between their Google Account and apps from other developers.\n\nWhat is confirmed and what is not: everything above comes from Google's own announcement. This review found no independent reporting or hands-on testing of the new endpoints, so details such as request formats, quotas and how suggestions behave in practice are not verified here. Google's developer documentation, which the announcement links, is the place to check them.\n\nWhy it matters: the suggestion mechanism gives software a way to contribute to a shared document without overwriting it, since a person still reviews the proposed change. That is relevant to anyone building review or editing workflows on top of Workspace, including those that use automated or AI-generated drafts. This is an interpretation, not a claim made in the announcement.\n\nRevised 16 October 2026: Guth re-read the original sources and rewrote this article. The earlier version remains available as revision 1.","content_kind":"author_paraphrase","explanation":{"feature":"Google says developers can now create, read and manage comments in Google Docs, Sheets and Slides through each product's developer API.","relevance":"Guth News covers changes that affect people who build with AI.
