Update tracking number

Hi team,

I have a transactional flow for order updates that is setup. The flow has order number, product details shipment details etc. that I can manually send to the customer who have placed orders.

Most importantly, I would like to share with each customer, the shipping tracking number and a url link pointing to the shipping partner’s website which I will get from my supplier

The question is.. how can i insert tracking number and url link manually to each email and send it to individual customers?

I am a newbie to Kalviyo and still learning, appreciate if you are able to advise how can I achieve this?

I am integrated with WooCommerce-Wordpress. 

Thank you,

Kris
