Inserted Record ID - how to pass between pages

Hi Teodor, could you point me in the right direction on how to do this please.

On page 1 I create a record in the order table. I have read the “how to obtain the inserted record ID” article and I can see that I have {{identity}} available as an action step following the database insert.

I want to pass this ID to page 2 where the detailed items on the order will be created. The ID of the order will then be included in each to the order_detail records.

How should I passing the ID between the pages please ?
