I have a domainA.com where users land and get an affiliation ID as a query parameter. https://www.domainA.com/?ID=86a0a Currently, I am storing this value on a cookie. If the user is interested on the product, they need to click on a link and it will drive you to domainB.com.
I know there is no way to share cookies between two domains, so my idea is to add the cookie value to the link click, again, as a query parameter. How can I do that?
