The commands are divided into two types: general commands and app commands.

General Commands

General commands operate on your Heroku account as a whole and aren’t specific to a particular app. For example, to get a list of apps that you created or are a collaborator on, run this command.

$ heroku apps
=== user@example.org Apps
example
example2

=== Collaborated Apps
collabapp                 owner@example.org

App Commands

App commands are typically executed from within an app’s local Git clone. The app name is automatically detected by scanning the Git remotes for the current working copy, so you don’t specify which app to operate on explicitly. For example, call the heroku apps:info command with --app or execute it without any arguments inside the working copy.

$ cd example
$ heroku apps:info
=== example-app-69977
Auto Cert Mgmt: false
Dynos:
Git URL:        https://git.heroku.com/example-app-69977.git
Owner:          your@emailaddress.com
Region:         us
Repo Size:      0 B
Slug Size:      0 B
Stack:          heroku-18
Web URL:        https://example-app-69977.herokuapp.com/

If you have multiple remotes or want to execute an app command outside of a local working copy, you can specify the remote name or an explicit app name as follows.

$ heroku apps:info --app example
$ heroku apps:info --remote production

Alternatively, specify the app name by setting the HEROKU_APP environment variable.

Using an HTTP Proxy

If you’re behind a firewall that requires a proxy to connect with external HTTP/HTTPS services, you can set the HTTP_PROXY or HTTPS_PROXY environment variables in your local developer environment, before running the heroku command.

If you get the error UNABLE_TO_GET_ISSUER_CERT_LOCALLY or ECONNREFUSED, it’s likely that you need a proxy.

For example, on a Unix system, run this command:

$ export HTTP_PROXY=http://proxy.server.com:portnumber
or
$ export HTTPS_PROXY=https://proxy.server.com:portnumber
$ heroku login

On a Windows machine, set it in the Environment Variables within System Properties or from the terminal.

> set HTTP_PROXY=http://proxy.server.com:portnumber
or
> set HTTPS_PROXY=https://proxy.server.com:portnumber
> heroku login

This command can go in your ~/.bashrc (or equivalent) to prevent running this every time you open a new shell session.

If your company’s internet requires the use of a MITM proxy, you can get a SELF_SIGNED_CERT_IN_CHAIN error. To the file location of the proxy’s Certificate Authority (CA) certificate in pem format, set NODE_EXTRA_CA_CERTS. Or if issued the self-signed certificate directly, set SSL_CERT_FILE or SSL_CERT_DIR to a file/directory containing the MITM certificate.

$ export NODE_EXTRA_CA_CERTS=/path/to/ca_cert.pem
$ heroku whoami
