Hi, I have registered in the developer.salesforce.com and want to connect rest api and get articles. I have done all steps using consumer key and consumer secret how is written in the documentation. After successfully authentication (OAuth) I have got access_token. Now I cannot get articles and I am getting this error [{"message":"Session expired or invalid","errorCode":"INVALID_SESSION_ID"}]. This is my URL and Header parts.
