I need to use an external API in my app in order to have companies informations. Beginning and having never used API in ruby, I don't know where to start. Maybe there is a gem for it but I have found 2 API that returns me JSON : https://datainfogreffe.fr/api/v1/documentation and https://firmapi.com/ (they're in french sorry about that). Does someone have a good tutorial or hints to help me begin ?
The final need is to retrieve companies datas just by giving the company ID.
You can use Net::HTTP to call APIs in Ruby on Rails.
uri = URI(url)
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
request = Net::HTTP::Post.new(uri.path, {'Content-Type' => 'application/json'})
request.body = {} # SOME JSON DATA e.g {msg: 'Why'}.to_json
response = http.request(request)
body = JSON.parse(response.body) # e.g {answer: 'because it was there'}
http://ruby-doc.org/stdlib-2.3.1/libdoc/net/http/rdoc/Net/HTTP.html
You need to use HTTP client library. There are a few popular libraries:
Net::HTTPYou can take a look and compare them on Ruby Toolbox: https://www.ruby-toolbox.com/categories/http_clients
Faraday is the most popular one. But it is the heaviest also because it covers most cases. So check documentation for each and depending on your task pick one that works the best.
