How can I add an order id to a marketing email?

[Marchy]

Hello,

I set up an automation workflow with "send marketing email".

And I want to add the order id as a variable. 

But the Liquid code is not working ({{ data.order.id }}).

Has anyone an idea to add the order id to a marketing email? Not to a automated notification email.

order_number

 Does that work?

First of all, thanks for your fast reply.

Unfortunately not I already tried that declaration 🙂
