Hi,

I have exposed a custom REST service through Apex code. I have given the following curl command to get the data from the API and it works fine if passed the session id in the header.

curl https://na30.salesforce.com/services/apexrest/testservice -H 'Authorization: Bearer 00D36000000wE02!ARAAQNag09f5_h7z8_ArS_JFo6f1o9Ag4C7y201UJDlyP66MSE1YrL7brsqS5CmCOO5' -H 'X-PrettyPrint:1'

But when I tried to use the Basic HTTP authentication it gives me below error. I have encoded the username and the password with base64

curl https://na30.salesforce.com/services/apexrest/testservice -H 'Authorization: Basic <username:password>'

[ { "message" : "Session expired or invalid", "errorCode" : "INVALID_SESSION_ID" }]

What I'm doing wrong here. Do I need to make any change in the back end code as well?
