Ideally you would do that on the server side, once a new post is saved. We have a plugin that exactly this for Amazon so you should be able to adapt it for eBay: [GitHub - discourse/discourse-affiliate · GitHub](https://github.com/discourse/discourse-affiliate)

If you still want to do it on the client side, you can follow this helpful tutorial: [Link rewriting for affiliate codes - #8 by Johani](https://meta.discourse.org/t/link-rewriting-for-affiliate-codes/52949/8)
