Using the API example from HaveAPI README, users would be listed with:

$ haveapi-cli --url https://your.api.tld --auth basic --username yourname --password yourpassword user list

Nested resources and object IDs:

$ haveapi-cli --url https://your.api.tld --auth basic --username yourname --password yourpassword user.invoice list 10

where 10 is user ID.

User credentials can be saved to a config:

$ haveapi-cli --url https://your.api.tld --auth basic --username yourname --password yourpassword --save user list

When saved, they don't have to be specified as command line options:

$ haveapi-cli --url https://your.api.tld user list

List options specific to authentication methods:

$ haveapi-cli --url https://your.api.tld --auth basic -h
$ haveapi-cli --url https://your.api.tld --auth token -h

List action parameters with examples:

$ haveapi-cli --url https://your.api.tld user new -h

Provide action parameters (notice the -- separator):

$ haveapi-cli --url https://your.api.tld user new -- --login mylogin --full-name "My Full Name" --role user

Client library

require 'haveapi/client'

api = HaveAPI::Client::Client.new('https://your.api.tld')
api.authenticate(:basic, user: 'yourname', password: 'yourpassword')

api.user.list.each do |user|
    puts user.login
end

user = api.user.find(10)
p user.invoice
user.destroy

p api.user.create({
  login: 'mylogin',
  full_name: 'Very Full Name',
  role: 'user'
})

user = api.user.new
user.login = 'mylogin'
user.full_name = 'Very Full Name'
user.role = 'user'
user.save
p user.id
