Easy SMS messaging

Last Updated: 19 March 2014

The add-on is currently in beta.

Table of Contents is an add-on for providing simple SMS messaging.

Adding SMS functionality to an application allows you to do account verification, offline alerting, send promotional offers, or any number of other possibilities simply by sending a message to both tradition mobile phones and smartphones. is accessible via a REST API and has easy integration options for any language and framework. Examples have been included for Ruby and Python.

Provisioning the add-on can be attached to a Heroku application via the CLI:

A list of all plans available can be found here.

$ heroku addons:add blowerio
-----> Adding blowerio to sharp-mountain-4005... done, v18 (free)

Once has been added a BLOWERIO_URL setting will be available in the app configuration and will contain the canonical URL used to access the newly provisioned service instance. This can be confirmed using the heroku config:get command.

$ heroku config:get BLOWERIO_URL

After installing the application should be configured to fully integrate with the add-on.

Local setup

Environment setup

After provisioning the add-on it’s necessary to locally replicate the config vars so your development environment can operate against the service.

Though less portable it’s also possible to set local environment variables using export BLOWERIO_URL=url.

Use Foreman to configure, run and manage process types specified in your app’s Procfile. Foreman reads configuration variables from an .env file. Use the following command to add the BLOWERIO_URL value retrieved from heroku config to .env.

$ heroku config -s | grep BLOWERIO_URL >> .env
$ more .env

Credentials and other sensitive configuration values should not be committed to source-control. In Git exclude the .env file with: echo .env >> .gitignore.

Using with Ruby

Ruby applications will need to add the following entry into their Gemfile specifying the Rest Client client library.

gem 'rest-client'

Update application dependencies with bundler.

$ bundle install

Then from within your application you can send an SMS by:

blowerio =['BLOWERIO_URL'])
blowerio['/messages'].post :to => '+14155550000', :message => 'Hello from'

Using with Python

In Python we recommend using the Requests library. The send a messaging using with Requests do the following:

import os
import requests['BLOWERIO_URL'] + '/messages', data={'to': '+14155550000', 'message': 'Hello from'})
