    • INT_URL=http://<your host or ip address>:3000/ #needed for exposing the integration running on port 3000
    • MM_URL=http://<your host or ip address>:8065/api/v4/ #needed for pointing to Mattermost installation

    • 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 local host or IP address (with port 3000) as the request URL
  • In OpenProject, create a custom field billable hours for all workpackages in a project
  • Test the integration by trying /op in the message bar.
