How To Use an API from your Ruby Server

Step 1
USE RESTCLIENT TO FETCH FROM API
The first thing we want to do is fetch from the API.

def from_api
 resp = RestClient.get("https://exampleapi.com/?api_key=1241241515151")
 render json: resp.body, status: :ok
end

Step 2
HIDE YOUR API KEY
If you need to hide your key you can do so by using a gem called Figaro.

gem "figaro"

Add figaro to to your gemfile, bundle install figaro and install figaro.

$ bundle exec figaro install

This creates a config/application.yml file and adds it to your .gitignore. You can use this to create Environment variables such as your key.

api_key: 1241241515151 (example)

And you can call it like this.

ENV['api_key'] 

> 1241241515151

Now use that key in your fetch request.

def from_api
    resp = RestClient.get("https://exampleapi.com/
?api_key=#{ENV['api_key']}")
    render json: resp.body, status: :ok
end
