Connecting MetronHR to the rest of your systems

There are four routes: a REST API for fetching and writing, 15 events as webhooks, an MCP server for AI assistants and sign-in through Microsoft Entra ID. Anyone who wants to work without writing code connects through n8n, Make, Zapier or Power Automate.

As of: 15. September 2026

An event from MetronHR runs through a webhook into an automation and from there into your system.

Which route for what

The choice depends on who is asking: a system, a process, an assistant, or a person who wants to sign in.

The technical details of the first three are on the page about the REST API, webhooks and MCP, and the sign-in is described on the page about single sign-on with Microsoft Entra ID.

Without writing code: the automation platforms

All four connect through a webhook and an HTTP block, set up in half an hour.

MetronHR with n8n

Self-hosted or in the cloud, with full access to the headers and the body. The platform with the least friction.

See the setup

MetronHR with Make

Visual scenarios, good error handling, billing by operation. The webhook is there at once, and the rest is an HTTP module.

See the setup

MetronHR with Zapier

The largest selection of apps on the market. The connection runs through Webhooks by Zapier, and that requires a paid plan.

See the setup

MetronHR with Power Automate

For businesses already on Microsoft 365. The trigger is built in; the HTTP action needs a premium plan.

What an access point may do, and what it may not

All routes share the same permission model. The rights hang per resource on "read" or "read and change", not on a role and not on all or nothing. A key for payroll therefore gets time entries and absences to read and nothing else.

Personal data under Art. 9 GDPR leaves the product through none of these routes. Bank details, date of birth, social insurance number and any disability status stay inside; for absences the type goes along, not the note. What sits where is set out in the Trust Center.

Where to go from here, and what waits for you there.

What is included in the price?

The REST API, webhooks and the MCP server belong to the Professional plan, at no extra charge and with no minimum number of licences. They are not included in the Team plan. Sign-in through Microsoft Entra ID is independent of that.

How does an external system sign in?

With an API key as a bearer token, created by management in the company settings. The rights are ticked per resource, "read" or "read and change". The plain text appears exactly once; only the checksum is stored.

Which route do I take for what?

A system that fetches data regularly: the REST API. A system that wants to know at once when something happens: webhooks. An AI assistant that is meant to answer questions: the MCP server. A process without code of your own: an automation platform with both.

Is there a connection to payroll?

Yes, through a file: the DATEV payroll export creates the payroll file for DATEV LODAS or DATEV Lohn und Gehalt each month, with your accountant's wage types. For other payroll software the hours go out as an Excel or CSV file or are fetched through the REST API. MetronHR does not run payroll itself, that stays with the accountant.
