Page Comparison

It is possible to create a site outside of CheckoutChamp that has login capability to a Membership Portal within CheckoutChamp. Any user that logs in will remain logged in when navigating between the sites. The user may also checkout using their card on file.

...

1. Place some kind of Login option on the Shopping site. When the Login option is chosen, redirect the user to the CheckoutChamp membership login page. The proper redirect format is https://www.membership.com/login?redirectToMe=https://www.shoppingsite.com/home

   • “www.membership.com/login” is the CheckoutChamp login page URL

   • “https://www.shoppingsite.com/home” is the Shopping site page where the user is to be returned after successful login

2. Place the following script into the body of all pages in the Shopping site

3. Set the membershipdomain variable on line 2 to your Checkout domain. This should be the domain only, not a specific page.

Set the shoppingdomain variable on line 3 to your Shopping domain. This should be the domain only, not a specific page.

4. For Chrome, Firefox, and Edge browsers, line 22 displays the returned value from the login event. The line can be removed. It is listed here as an starting point to display login information on the Shopping site, such as a first and last name. This is optional.

5. Safari browsers need additional attention to properly store the SSO cookie [Chandra - I do not understand the steps in your document. Let us work on steps that are obvious to less experienced developers. Please provide an example.]

Code Block
language js
<script> var membershipdomain = "https://www.membership.com"; var shoppingdomain = "https://www.shoppingsite.com"; var ifrm = document.createElement("iframe"); ifrm.setAttribute("id", "ifmcrossoriginid"); ifrm.setAttribute("name", "ifmcrossorigin"); ifrm.setAttribute("src", membershipdomain + "/iframe.html?shoppingdomain=" + shoppingdomain); ifrm.setAttribute("class", "btn-primary"); ifrm.style.width = "109px"; ifrm.style.height = "36px"; ifrm.style.border = "none"; if(!navigator.userAgent.includes("Chrome") && navigator.userAgent.includes("Safari") && document.referrer === membershipdomain){ ifrm.style.display = "block"; document.getElementById("modal_request_access").appendChild(ifrm); } else { ifrm.style.display = "none"; document.body.appendChild(ifrm); } window.addEventListener("message", (event) => { if (event.origin !== membershipdomain) return; if(event.data == "logoutSuccess") { //write code to clear all the session information in your application } // This event.data will have the first name and the last name. console.log(event.data); } , false); function logoutMembership(){ var iframe = document.getElementById('ifmcrossoriginid'); var win; try { win = iframe.contentWindow;} catch(e) { win = iframe.contentWindow;} win.postMessage("logout", membershipdomain); } </script>

6. Edit the script and page as follows:

   • Set the membershipdomain variable on line 2 to your Checkout domain. This should be the domain only, not a specific page.

   • Set the shoppingdomain variable on line 3 to your Shopping domain. This should be the domain only, not a specific page.

   • For Chrome, Firefox, and Edge browsers, line 23 displays the returned value from the login event. The line can be removed. It is listed here as an starting point to display login information on the Shopping site, such as a first and last name. This is optional.

   • Safari browsers require user acceptance of the SSO cookie

     • Add a modal form to the Shopping site. The screenshot below is an example.

     • Inside the modal window, create a container section to display buttons. In the screenshot example, the id of this container is “modal_request_access“. Be sure the id given for the container matches line 14 in the body script.

     • After login the container will be used by the script iframe to display an ‘Allow Access’ button.

     • Once the user clicks the 'Allow Access’ button, the Safari browser will prompt the user to allow access to read the Membership domain storage. Once the user allows that, line number 23 will have the user data.

1. Place some kind of Login option on the Shopping site. When the Login option is chosen, redirect the user to the CheckoutChamp membership login page. The proper redirect format is https://member.shoppingsite.com/login?redirectToMe=https://www.shoppingsite.com/home

   • “member.shoppingsite.com/login” is the CheckoutChamp login page URL

   • “https://www.shoppingsite.com/home” is the Shopping site page where the user is to be returned after successful login

2. Once the user is redirected back to the shopping site, access document.cookie to read the user information. You can also add the following script to read the cookie and add it as a separate javascript objects.

const cookieData = {};
if (document.cookie) {
    var cookies = document.cookie.split(";")
    cookies.forEach(function (d) {
        var cookieName = d.split("=")[0].trim();
        var cookieVal = d.split("=")[1].trim();
        if (cookieVal) {
            cookieData[cookieName] = cookieVal;
        }
    })
}
