Authentication

The mapi CLI communicates with our API using OAuth 2.0 Bearer Tokens. The token will be read by the environment variable, MAPI_TOKEN, if available.

To get a new token, visit the "Manage API Tokens page" to create a new token, <NEW_TOKEN>, and login:

$ mapi login <NEW_TOKEN>

Welcome to Mayhem for API! We have saved a new API token in
your local settings at '/Users/mapi_fuzzer/Library/Preferences/rs.mapi/mapi.toml':

Setting the displayed API Token to the environment variable, MAPI_TOKEN, will allow you to run the CLI on other computers, such as part of your Continuous Integration build.

Now you can try contacting the API. Let's get the list of targets to which you have access:
