The following environment variables must be set: FLOCKY_TOKEN,FLOCKY_USERNAME,FLOCKY_PASSWORD,FLOCKY_APPNUM These are the API token, username, password, and appnumber for your tropo app

you can get your appnumber by visiting

App domain redirects from heroku URL using heroku config variable. To set the key APP_DOMAIN use: heroku config:add --app

on heroku, the following plugins are used: sendgrid, cloudmailin, cron

Setting up incoming email:

  1. install the cloudmailin plugin on heroku

  2. look at 'heroku config' for your app, to get the username and password

  3. on, add the desired incoming domain as a custom domain

  4. on your DNS server, add '' as a CNAME for your desired subdomain/domain.

Submitting an Issue

We use the GitHub issue tracker to track bugs and features. Before submitting a bug report or feature request, check to make sure it hasn't already been submitted. You can indicate support for an existing issuse by voting it up. When submitting a bug report, please include a Gist that includes a stack trace and any details that may be necessary to reproduce the bug, including your gem version, Ruby version, and operating system. Ideally, a bug report should include a pull request with failing specs.

Submitting a Pull Request

  1. Fork the project.
  2. Create a topic branch.
  3. Implement your feature or bug fix.
  4. Add tests for your feature or bug fix.
  5. Run bundle exec rake test. If your changes are not 100% covered, go back to step 4.
  6. Commit and push your changes.
  7. Submit a pull request. Please do not include changes to the gemspec or version file. (If you want to create your own version for some reason, please do so in a separate commit.)

Supported Rubies

This library aims to support and is tested against the following Ruby implementations:

  • Ruby 1.8.7
  • Ruby 1.9.2
  • Ruby 1.9.3

If something doesn't work on one of these interpreters, it should be considered a bug.

This library may inadvertently work (or seem to work) on other Ruby implementations, however support will only be provided for the versions listed above.

If you would like this library to support another Ruby version, you may volunteer to be a maintainer. Being a maintainer entails making sure all tests run and pass on that implementation. When something breaks on your implementation, you will be personally responsible for providing patches in a timely fashion. If critical issues for a particular implementation exist at the time of a major release, support for that Ruby version may be dropped.
