Thanks for the details. &nbsp;From the article links, the requests are raised from server side and not from client side call(Ajax).<br />
<br />
What we are planning to do is expose features via asp.net web api. Our clients can call them directly from their html page and process the results which are in JSONP format.

Hi,<br />
&nbsp; &nbsp; We are exposing some api via asp.net web api to third parties. They get data from us using JQuery Call and display in their pages. &nbsp;The response goes in JSONP. The calls involve cross domain. Web api is hosted in IIS. SSL is enabled<br />
<br />
We don't have login page for them. Given this situation how can i authenticate calls for my web api. I need to allow only my known thrid parties and not every body. <br />
<br />
Please suggest me a ways of implementing this.

asp.net Web api authentication from ajax cross domain call

Asynchronous JavaScript and XML (AJAX) is a group of interrelated Web development techniques used on the client-side to create asynchronous Web applications. With AJAX, web applications can send data to and retrieve from a server asynchronously (in the background) without interfering with the display and behavior of the existing page. HTML and CSS can be used in combination to mark up and style information. The Document Object Model (DOM) is accessed with JavaScript to dynamically display and allow interaction with the information presented.

AJAX

jQuery (Core) is a cross-browser JavaScript library that provides abstractions for common client-side tasks such as Document Object Model (DOM) traversal, DOM manipulation, event handling, animation and Ajax. jQuery also provides a platform to create plugins that extend jQuery's capabilities beyond those already provided by the library.

jQuery

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
