In order for Snyk to be able to monitor your deployed Heroku applications, you’ll first need to connect Snyk to your Heroku account. You can do this by navigating to the Integrations page and clicking on “Connect to Heroku”.
This will take you to a page where you’ll be prompted to enter your Heroku API Key. There is only one API Key per Heroku user so we recommend setting up a dedicated user for your Snyk organization.
Instructions for how to generate and locate your Heroku API key are below.
You can find and generate your Heroku API key in your “Account Settings” section of your Heroku Account.
Alternatively, you can use the Heroku CLI to generate your API key and copy it directly to your clipboard:
heroku auth:token | pbcopy
From there you can login to your Snyk account and paste in your Heroku credentials.
At any time after you’ve entered your Heroku credentials, you can check on the connection status in one of two places.
The first is on your integration settings page, where you’ll see your current integrations listed as well as their connection status.
The connection status is also displayed directly on the Heroku integration settings page (found by clicking “Edit settings” on the integration settings page shown above). If you’ve entered credentials, you’ll see a box indicating whether or not Snyk is able to correctly connect to Heroku.
If you are unable to connect, please re-enter your account credentials to verify that they are correct.
On Heroku, each user is limited to one API key so we suggest adding a dedicated user for your Snyk org. That way if at some point you need to revoke the key for any reason, you can do so without impacting anyone within your org.
This can be accomplished through the Heroku admin interface, or from the command line using the following command:
heroku access:add email@example.com
You can learn more about how to add another user to your application on the Heroku documentation.
Once you’ve successfully connected Snyk to your Heroku account, you’ll be able to select Heroku projects that you would like Snyk to monitor. You can do this either using the “Add projects” button on the integrations page or directly from the Heroku integration settings page.
In either case, you’ll see a list of any available projects on the Heroku account you connected. Select the ones you want to monitor and click the “add to Snyk” button.
As soon as you’ve added the projects to Snyk, Snyk will test them and begin to display a list of all monitored Heroku applications in your project dashboard. You’ll also see a snapshot of any current vulnerabilities, and be able to click through for a more detailed report including any steps to remediate.
Snyk will now continuously monitor each of those projects for known vulnerabilities. You can add more projects at any time.
