Poor man's basic authentication

Add this line to your application's Gemfile:

gem 'guardian'

And then execute:

$ bundle

Or install it yourself as:

$ gem install guardian

Include Guardian in your specific controller or a base one

class ApplicationController < ActionController::API
  include Guardian

  rescue_from Guardian::Unauthenticated do |error|
    render json: { error_human: error }, status: :unauthorized
  end

  rescue_from Guardian::Unauthorized do |error|
    render json: { error_human: error }, status: :forbidden
  end
end

And use authenticate! method to check whether user provided credentials

class PetsController < ApplicationController
  before_action :authenticate!, only: %i[create update delete]

  def create
    # create a pet
  end
end

Done! Whoah
