How can I match the checkout process with the 'orders/paid' webhook?

[hauseja3]

Hello, 

I am facing a problem that I am not able to match the checkout process (AJAX API) with the `orders/paid` webhook. 

Firstly, we have tried to put a `note` into the cart via AJAX API Update cart note. However, this `note` is not shown in `orders/paid` webhook. 

Secondly, I tried to match it using `cart_token`. Getting it from AJAX API Get cart. Sending and storing it in our database and then matching it with the order since `cart_token` is also present in `orders/paid` webhook. Unfortunately, the `cart_token` is changing and I cannot match it. 

What would you recommend to use for our use case? Is there any way how to match cart/checkout process with the `orders/paid` webhook, please? Why is the `note` or `cart_token` not working? 

I need to: 
1. Get some information from the cart (AJAX API) during the checkout process

2. Store this information into our database together with our shoping entity 
3. When received `orders/paid` webhook, matching the order with our shoping entity
