WooCommerce mapping

I need to add a field called “PO #” to my packing slip / invoice (we ship B2B and the customer needs to reference the product I ship them with their PO.) What field in WooCommerce can I enter the Purchase order # in so when it gets to ShipHero I can print it on my Packing Slip / Invoice?

Hello @Grayland
Welcome to the ShipHero Public API Community!

Are you trying to use our API in some way to accomplish this?

Have a great day,

I put in a support ticket and they told me to post the question here. So yes I assume I am using your API…would there be any other option for this?

I just know I have a Woo Commerce store and need to pull an additional field into ShipHero so I can add it to our packing list / invoice.
