REST API:Session expired or Invalid error


Please help me in understanding,Is OU Auth 2.0 the only way to interact with salesforce using rest API'S or does is support the session Id(I,e the session Id we get as part of login menthod in SOAP API).

I am trying to call Query method of REST API by passing the session Id as Authorization header, I get from login method of SOAP API.I am getting below error:
      <message>Session expired or invalid</message>

below is the url I am calling by passing Authorization header with the value of session Id I am getting from login method form SOAP API. ID,name from Contact

Please help.Are there any SOAP UI test cases or samples to refer.I am trying to test from SOAP UI.

Hi Rathna,

You can authenticate using the session ID as well for the REST API. However, you need to add a word "Bearer " infront of the session Id.

e.g.: req.setHeader('Authorization',  'Bearer sessionid_here');
