Convert Rest API call from PHP to RUBY - php

Question

Im trying to convert a post connection to the walmart api, from php to ruby, this is the php version
$client_id = $data['client_id'];
$client_secret = $data['client_secret'];
$url = "https://marketplace.walmartapis.com/v3/token";
$uniqid = uniqid();
$authorization_key = base64_encode($client_id.":".$client_secret);
$code = "";
$ch = curl_init();
$options = array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_TIMEOUT => 60,
CURLOPT_HEADER => false,
CURLOPT_POST =>1,
CURLOPT_POSTFIELDS => "grant_type=client_credentials",
CURLOPT_HTTPHEADER => array(
"WM_SVC.NAME: Walmart Marketplace",
"WM_QOS.CORRELATION_ID: $uniqid",
"Authorization: Basic $authorization_key",
"Accept: application/json",
"Content-Type: application/x-www-form-urlencoded",
),
);
curl_setopt_array($ch,$options);
$response = curl_exec($ch);
$code = curl_getinfo($ch,CURLINFO_HTTP_CODE);
curl_close($ch);
and this is what i have so far:
url = "https://marketplace.walmartapis.com/v3/token/"
uniqid = "1234567890a1b"
uri = URI.parse(url)
request = Net::HTTP::Post.new(uri)
request["WM_SVC.NAME"] = "Walmart Marketplace"
request["WM_QOS.CORRELATION_ID"] = uniqid
request.basic_auth(client_id, client_secret)
request["Accept"] = "application/json"
request.content_type = "application/x-www-form-urlencoded"
request["WM_SVC.VERSION"] = "1.0.0"
req_options = {
use_ssl: uri.scheme == "https",
}
response = Net::HTTP.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https') do |http|
http.request(request)
end
puts "error " + response.code
puts response.body
Now, im getting a 400 error, so something of the data im sending is incorrect or missing... comparing both, i dont have set the postfields option on ruby, for the POST request, not sure if the rest is required as well... any ideas?

Answer 1

Try adding this line:
request.body = 'grant_type=client_credentials'
