Curl request with PHP - Where can I find parameters ?

in Refinitiv Data Platform

I'm trying to make a curl request with PHP to the endpoint https://api.refinitiv.com/auth/oauth2/v1/token in order to get an access_token, which I can then use to access the other endpoints that Refinitiv provides. However, I'm encountering some difficulties. From what I understand, the following fields are mandatory:

  • grant_type ("password")
  • username (my email address)
  • password (my password)

On the other hand, I have no idea where I can find the following information:

  • scope
  • client_id
  • client_secret

Having combed through the rather thin associated documentation, the client_id and client_secret would be associated with my application created via the AppKey Generator, but if the field names matched what I can see there, that would be too easy. So, do you know where I can find the "scope" parameter, and what do "client_id" and "client_secret" correspond to in the AppKey Generator?

Thank you very much for your help!

    The PHP code for Authentication V1 should look like this:

    <?php
    $curl = curl_init();
    curl_setopt_array($curl, array(
      CURLOPT_URL => 'https://api.refinitiv.com/auth/oauth2/v1/token',
      CURLOPT_RETURNTRANSFER => true,
      CURLOPT_ENCODING => '',
      CURLOPT_MAXREDIRS => 10,
      CURLOPT_TIMEOUT => 0,
      CURLOPT_FOLLOWLOCATION => true,
      CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
      CURLOPT_CUSTOMREQUEST => 'POST',
      CURLOPT_POSTFIELDS => 'username=<username>&password=<password>&grant_type=password&scope=trapi&takeExclusiveSignOnControl=true&client_id=<client id>',
      CURLOPT_HTTPHEADER => array(
        'Content-Type: application/x-www-form-urlencoded'
      ),
    ));
    $response = curl_exec($curl);
    curl_close($curl);
    echo $response;

    This code is generated by Postman. You can download the RDP Postman collection from here and refer to this article: Generate code for a REST API call using Postman in just a few clicks regarding how to generate code from Postman

    Yes, you can use CURL to get an access token. Use following command:

    curl -v -X POST -H "Accept: application/json" -d "username=<<__MACHINE_ID__>>&password=<<__PASSWORD__>>&client_id=<<__APP_KEY__>>&grant_type=password&scope=trapi&takeExclusiveSignOnControl=true" https://api.refinitiv.com/auth/oauth2/v1/token

    replace the parameters with your username/machineID, password and APP Key.

    This quickstart guide shows how to create your app key.

    Thank you both for your answers, you have solved my problem! It's puzzling not to simply have a public key and a private key like any other API, and you can't say that the documentation is very clear on that... One must guess that the client_id is the API key haha.

    Yes, the public/private key pair support is enabled in the v2 authentication - which will also allow the JWT keypair for authorization.
