I am trying Mautic on Ruby. When I send a GET HTTP request to ‘[http://my-mautic/api/contacts?access\_token=my\_access\_token](http://my-mautic/api/contacts?access_token=my_access_token)’ with a header ‘Authorization: Bearer my\_access\_token’, I get the Internal Server Error (500). The log (‘my-mautic/s/sysinfo’) says

Code:

[2017-07-27 09:31:48] mautic.CRITICAL: Uncaught PHP Exception OAuth2OAuth2AuthenticateException: "invalid\_request" at /home/foo/bar/public\_html/ma/vendor/friendsofsymfony/oauth2-php/lib/OAuth2.php line 570 {"exception":"[object] (OAuth2\OAuth2AuthenticateException(code: 0): invalid\_request at /home/foobar/public\_html/ma/vendor/friendsofsymfony/oauth2-php/lib/OAuth2.php:570)"} []

What I did is:

Code:

require 'faraday'; require 'faraday\_middleware' token = 'my\_access\_token' conn = Faraday.new(url: 'http://my-mautic/api') do |f| f.request :oauth2, token f.request :url\_encoded f.request :json f.response :json f.adapter Faraday.default\_adapter end conn.headers['Authorization'] = "Bearer #{token}"

res = conn.get(‘contacts’)  
puts res.status  
#=\> 500  
puts res.reason\_phrase  
#=\> Internal Server Error

  
Environments:

Code:

ruby 2.3.1 faraday 0.10.0 faraday\_middleware 0.10.1
