Automate workflows with custom starters and steps, third-party integrations, and webhooks in Workspace Studio

To expand the capabilities of Workspace Studio and help teams build powerful, custom automations, we are introducing four new features for flows in Workspace Studio: custom starters, custom steps, third-party (3P) integrations, and webhooks. These new capabilities empower users to seamlessly connect custom Google Apps Script functions, integrate third-party services, and trigger external webhooks directly within flows in Workspace Studio.

All of these features are backed by granular enterprise security controls that allow admins to safely enable and adopt agentic capabilities across their organizations.

• Custom starters: Build and publish custom, real-time triggers to run flows based on events in other applications.

• Custom steps: Build and run custom logic (e.g. using Apps Script) and tailor flows to advanced business needs.

• Third-party integrations (Beta): Connect third-party applications and services to pass data effortlessly between Workspace and external tools to automate your business flows. The following integrations are available:
  • Asana
  • Confluence
  • Hubspot
  • Jira
  • Mailchimp
  • Quickbooks
  • Salesforce
  • Slack

• Webhooks: Send HTTP requests to external endpoints and trigger actions in them. On supported editions, admins can set an URL allowlist for webhook access.

  • These features are OFF by default. Admins can enable them in the Workspace Admin Console under Apps > Google Workspace > Workspace Studio:
