Peoplesoft to ORCID integration

[its....@gmail.com]

Has anyone integrated Peoplesoft pages with ORCID.Please let me know any alternative to curl command.

Instead of using curl , I am trying to call https://sandbox.orcid.org/oauth/token through REST webservice but getting the following exception :

POST Url : https://sandbox.orcid.org/oauth/token?client_id=xxx&client_secret=xxx&grant_type=authorization_code&code=<code returned after authorize>&Accept=application/json&redirect_uri=<peoplesoft page>

Output :

<InvalidClientException>

    <error>invalid_client</error>

    <error_description>Client not found: </error_description>

</InvalidClientException>

Instead of passing values as params , I have also tried passing the values in body of the request in xml format but I am getting the same exception.
