Connecting MetronHR to Zapier

Zapier receives deliveries from MetronHR with "Catch Hook" and calls the REST API through the "Webhooks by Zapier" action. Both are premium apps and require a paid plan. There is no MetronHR entry in the app directory.

As of:15. September 2026

In the app directory ofZapier there is no ready-made MetronHR entry, and this page claims none. What there is, is the route Zapier provides for any HTTP service: an incoming webhook as the trigger and an HTTP block for the call. Both are set up in half an hour and need no connector.

The two directions

MetronHR reports of its own accord through Webhooks and answers requests through the REST API. Both routes belong to the Professional plan.

  • MetronHR reports an event

    Block in Zapier
    Webhooks by Zapier, "Catch Hook"
    What to do
    Zapier creates an address and shows the payload received for the field mapping. "Catch Raw Hook" delivers the unchanged body that the signature check needs.

  • Zapier asks MetronHR

    Block in Zapier
    Webhooks by Zapier, "Custom Request"
    What to do
    Method, address and headers are yours to choose. The key goes in front as Authorization with Bearer.

As of 15. September 2026. The interface address is https://app.metronhr.de/api/v1, and what is binding is the app's OpenAPI document.

Sending a message when a holiday request is declined

A process that works in this shape. Steps one and three happen in MetronHR, the rest inZapier.

  1. 1In MetronHR create a target and subscribe to absences.rejected.
  2. 2In Zapier start a Zap with Catch Raw Hook and enter the address.
  3. 3Trigger the test delivery in MetronHR so Zapier knows the structure.
  4. 4Add a filter step if only certain departments are meant.
  5. 5Send the message in the channel you want, taking the fields from data.

What to watch for on theZapier side

  • Webhooks by Zapier is a premium app. It is not available on the free plan, and without it there is no route to MetronHR.
  • Zapier runs in data centres outside the EU. Anyone sending working time and absence data there needs a legal basis for it and a data processing agreement with the provider. That is a decision before the setup, not after it.
  • For the signature check "Catch Raw Hook" is required; the parsed variant changes the body, and the HMAC no longer matches.

A key carries only the rights ticked when it was created, per resource "read" or "read and change". For a process that only reports, reading is enough. Anyone who would rather have an AI assistant ask instead of a process takes the MCP server.
