    • 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

    • MATTERMOST_ACCESS_TOKEN=<personal access token> #https://docs.mattermost.com/developer/personal-access-tokens.html
    • MATTERMOST_SLASH_TOKEN=<use the mattermost slash command token for logtime> #needed for slash command validation
    • MATTERMOST_BOT_TOKEN=<use the mattermost bot access token> #needed for validation for posting messages as bot
    • 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
  • In OpenProject, create a custom field billable hours for all work packages in a project
  • Test the integration by trying /op in the message bar.
