Answer 1

Please read about set request header: XMLHttpRequest.setRequestHeader

XMLHttpRequest.setRequestHeader(header, value)

you can use XMLHttpRequest.setRequestHeader API to set header for any request.

For OAuth you can read more: OAuth.

In your case to implement OAuth to get the token

POST /oauth/initiate

The following request parameters should be present in the Authorization header:

oauth_callback - an URI to which the Service Provider will redirect the resource owner (user) after the authorization is complete.
oauth_consumer_key - the Consumer Key value, retrieved after the registration of the application.
oauth_nonce - a random value, uniquely generated by the application.
oauth_signature_method - name of the signature method used to sign the request. Can have one of the following values: HMAC-SHA1, RSA-SHA1, and PLAINTEXT.
oauth_signature - a generated value (signature).
oauth_timestamp - a positive integer, expressed in the number of seconds since January 1, 1970 00:00:00 GMT.
oauth_version - OAuth version.

Good Luck! :)
