AI Agent Integration via Jentic

AI agents discover and call Invoices endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle oauth2 tokens manually.

Search Jentic for 'create draft invoice', load the operation schema, and execute with Jentic-managed credentials

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Invoices oauth2 credentials are stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped access tokens — raw secrets never enter the agent context.

Intent-based discovery

Agents search by intent (e.g., 'create draft invoice') and Jentic returns the matching Invoices operation with its input schema, so the agent can call the right endpoint without browsing docs.

Time to first call

Direct Invoices integration: 1-3 days for auth handling, response parsing, and error cases. Through Jentic: under 1 hour — search, load schema, execute.
