Conversion URL with order id [ Edited ]

[#1]

Hello community.

In the past I was getting conversion url with order id for every single purchase. This info was available to me under Conversion section, under webpages. I could see every single conversion with different order id like this (this is just example):

http://domain-name.com/order-received/76500

http://domain-name.com/order-received/76542

Now, recent changes to the shop were made and now I only see unique url in Adwords for all orders like this one:

http://domain-name.com/thank-you

Altough we included order id part at the end we now don't see it anymore. Does anybody know how to fix it to show individual urls? The one thing I was told was changed is that they started using Google Tag Manager for Adwords conversion tracking.

Good morning.

I don't know all of the details about Tag Manager, but this help page might be useful to your account manager and website manager.

How can I set up an order ID for website which is not an ecommerce website? Can I just randomly type order ID? Anyone can show me step by step? Then how can I add those info in tag manager to track?

Thank you
