I am learning and using Web API and need to implement following Authentication mechanism:

Very First call to Web API will be a Handshaking (Login and token
sharing). Login Method of the Web API will be called with the proper
credentials, once approved a GUID based Token will be returned to the
Client( A Jquery or Windows based). Token will be expired after some
configurable time.

Till then, client should be able to communicate with the WebAPI with
sharing the same token value with every requests, thus wouldn’t need
to authenticate each call.

For having Token in each call, it is quite possible to have it in each
QueryString or have it in each param of the Web API method.

But, I am looking for the possibilities Where Token can be embedded with the HTTPRequestHeader via JQuery (using AJAX calls) or Windows based clients. I would like if you guys could help me to identify the fair approach to implement this system and perils in advance.

    You can modify the headers in jQuery using beforeSend method when using jQuery Ajax.

    Adding / Modifying HTTP Request Headers using HttpClient is no problem.

    Maybe Thinktecture.IdentityModel.Http will support your described scenario soon: Thread: Web API Sample for Thinktecture.IdentityModel at WebApiContrib Google Group

    Some token based authentication mechanism like SWT and SAML 1.1 / 2.0 are already implemented in Thinktecture.IdentityModel.Http.
