Mews Open API allows Mews Operations to connect with local devices (such as printers, passport scanners, and key encoders), so commands can be sent directly from Mews to your devices.

Step 1: Set up your Mews Open API token

  1. Go to Main menu > Marketplace.
  2. In the Facility management section, click See more under the Mews Open API integration.
  3. Click Connect.
    - When the integration has been successfully connected, click OK. You will be redirected to the My subscriptions tab.
  4. In your list of active integrations, find Mews Open API and click Settings.
  5. In the Connected devices field, add any passport scanners, printers, or key cutters that you currently have set up.
  6. Click Save.

Step 2: Download and install Mews Open API

We recommend that you download Mews Open API onto the same computer or server as your local devices (for example, key cutters or printers). This computer must be:

  • A Windows PC (Vista and later supported).
  • A computer that never shuts down (when the computer shuts down, Mews Open API stops working).
  1. Go to to download the Mews Open API application.
  2. Find a file called Connector_InstallMewsConnector.exe in your downloads folder.
  3. Double-click on the file to run the Mews Open API application.
  4. Follow the on-screen instructions to complete the installation.
  5. If your key cutter software communicates with Mews using the FIAS protocol, complete the following fields in your FIAS settings:
    - Fias Server Port - Enter the port number of your door lock application (for Kaba Saflok, use 8265).
    - Client Mode - Enable this if you're using the Kaba Saflok key cutter integration.
    - Enabled - Select this since you're using FIAS.

How do you know if your key cutter uses FIAS? You can tell your key cutter software communicates with Mews using the FIAS protocol if, during the setup of your key cutter integration in Mews Operations, you entered { "Type": "FiasProtocol" } into the Data JSON field. Alternatively, you can find a list of our currently supported FIAS key cutters here.

Note: More advanced setup (for example, virtual server installation) is possible as long as all of your devices are connected to one network — reach out to your Account Manager for more info.
