As with all Heroku add-ons, you can also create a new add-on locally using the Heroku CLI tool:
heroku addons:create interplanetary-fission:test
If you create the add-on through the Heroku dashboard, you can find your API credentials in the Settings section of your app, under the Config Vars heading:
These can also be used in your local environment by creating an .env file.
The Heroku Add-on uses the Web API, appropriate for server side apps written in any language that Heroku supports. You can browse the live docs of the Fission Web API at runfission.com/docs, or look at our Github repo to find a client SDK for your programming language.
Deploy to Heroku
A particularly good use case for using our Fission IPFS add-on is to combine it with setting up your application in a "Deploy to Heroku" mode.
