Attio releases App SDK 1.0 and lets teams rename system objects

On August 25, 2026, Attio published changelog entries for its developer platform, object naming, Workflows apps and blocks, the sidebar and a digest of smaller changes. The developer entry lists six API and MCP additions, a Zapier trigger for new call recordings, the 1.0.0 App SDK release and a new Developer Changelog. Separate entries cover renaming system objects and connecting Google Sheets, Asana and Hunter to Workflows, and a digest adds native dictation in Ask Attio.

The details

• The App SDK reached version 1.0.0.
• The API supports creating meetings and call recordings, including transcript-only uploads from Granola.
• Records can be merged through the API or MCP in the same way as the in-app merge.
• System objects such as Deals, Workspaces and Users can be renamed with new icons.
• Workflows apps were added for Google Sheets, Asana and Hunter.
