ZAIA generates the workflow structure and includes the right integration steps for the tools you describe. The connections themselves are handled through two mechanisms in Zenphi, and ZAIA uses whichever applies.
The first is first-class actions. Zenphi has native actions for Google Workspace, Microsoft 365 — Entra ID, Teams, Outlook, Word, OneDrive, SharePoint, and Excel Online — and 100+ other tools such as Salesforce, HubSpot, QuickBooks, Xero, Jira, Asana, Slack, DocuSign, and Stripe. When you describe a workflow that uses one of them ("update the Salesforce opportunity when the contract is signed"), ZAIA adds that action step; you choose the operation, map the fields, and authenticate once.
The second is HTTP and webhook actions. For a system without a first-class action — a proprietary internal tool or a custom API — Zenphi's HTTP action makes any REST call from a workflow step, with method, headers, authentication, body, and response mapping. ZAIA adds the HTTP step and indicates the API parameters you'll need to configure.
If you're not sure whether Zenphi has a first-class action for a tool, describe the workflow to ZAIA: it validates every step against the live action catalogue and tells you what's available. New first-class actions ship regularly, with new Microsoft actions added every month, and the integrations directory lists what's available today.
