ADDON-NAME is an add-on for providing functionality X.
Adding functionality X to an application provides benefits X, Y, and Z.
Access ADDON-NAME via its API or its client libraries for [[Java|Ruby|Python|Node.js|Clojure|Scala|PHP|Go]]*.
Provisioning the Add-on
Attach ADDON-NAME to a Heroku application via the CLI:
Reference the Add-on Name Elements Page for a list of available plans and regions.
$ heroku addons:create ADDON-SLUG
Creating ADDON-SLUG on sharp-mountain-4005... free
Your add-on has been provisioned successfully
After provisioning ADDON-NAME, the ADDON-CONFIG-NAME config var is available in the attached app’s configuration. It contains the [[variable purpose, for example, “canonical URL used to access the newly provisioned ADDON-NAME service instance.”]]. You can see the config var via the heroku config:get command:
$ heroku config:get ADDON-CONFIG-NAME
http://user:pass@instance.ip/resourceid
After installing ADDON-NAME, the application is fully configured to integrate with the add-on.
Local Setup
Environment Setup
[[If running against the add-on service during development isn’t applicable, omit this section.]]
After provisioning the add-on, replicate its config vars locally for development environments that need the service.
Use the local Heroku CLI command to configure, run, and manage process types specified in your app’s Procfile. Heroku Local reads configuration variables from a .env file. Use heroku config to view an app’s configuration variables in a terminal. Use the following command to add a configuration variable to a local .env file:
$ heroku config:get ADDON-CONFIG-NAME -s >> .env
Don’t commit credentials and other sensitive configuration variables to source control. In Git exclude the .env file with: echo .env >> .gitignore.
For more information, see the Heroku Local article.
Service Setup
[[If there’s a local executable required (like for the Memcache add-on), include installation instructions. If not, omit the entire section.]]
You can install ADDON-NAME for use in a local development environment. Typically, this process entails [[installing the software | creating another version of the service]] and pointing the ADDON-CONFIG-NAME to this [[local | remote]] service.
| On… | Install with… |
|---|---|
| macOS | brew install X |
| Windows | Link to some installer |
| Ubuntu Linux | apt-get install X |
| Other | Link to some raw package |
Language-Specific Integrations

[[Repeat this ###Rails section for all other supported languages and frameworks, including Java, Node.js, Python, Scala, Play!, Grails, Clojure. Heroku is a polyglot platform - don’t box yourself into supporting a single language.]]
Add the following to the Gemfile, specifying the ADDON-NAME client library.
gem 'ADDON-SLUG'
Update the application dependencies with bundler.
$ bundle install

Migrating Between Plans
Application owners must carefully manage the migration timing to ensure proper application function during the migration process.
[[Specific migration process or any migration tips and tricks.]]
Use the heroku addons:upgrade command to migrate to a new plan.
$ heroku addons:upgrade ADDON-SLUG:newplan
