Instagram API - Unable to request access token

Question

Using HTTParty I tried to request for the access token as below:

result = HTTParty.post("https://api.instagram.com/oauth/access_token",
{ 
  :body => [ { "client_id" => xxxxxxxxxx, "client_secret" => xxxxxxxxxxxxx,
  "grant_type" => "authorization_code",
  "redirect_url" => 'http://localhost:4000/access_token', "code" => xxxxxxxx } ].to_json,
  :headers => { 'Content-Type' => 'application/json', 'Accept' => 'application/json'}
})

But the response says that #400, "error_type"=>"OAuthException", "error_message"=>"You must provide a client_id"}, @response=#, @headers={"content-language"=>["en"], "expires"=>["Sat, 01 Jan 2000 00:00:00 GMT"],........

Can't figure out why.. Help!

Answer 1

You can change content-type into:

'Content-Type' => 'application/x-www-form-urlencoded'
