    • OP_URL=http://<your host or ip address>:8080/api/v3/ (needed for pointing to OpenProject installation)
    • INT_URL=http://<your host or ip address>:3000/ (needed for exposing the integration running on port 3000)

    • OP_ACCESS_TOKEN=<openproject access token (a.k.a apikey) obtained from user account page>
  • In the project root directory do npm init to generate (or update existing) package.json file
  • Then run npm install to download and install the node modules from npm
  • Run op-mattermost in the console using npm start (usually launches on port 3000)
  • Create a custom Mattermost slash command /op as described here and provide localhost or IP address (with port 3000) as the request URL and method as POST
