How can I distinguish between pick up and click and collect orders via order API?

Hi I would like to know how I can distinguish if order is pick up order or click and collect order via order api.

Hello,

You can use the ‘delivery_method’ field on the FulfillmentOrder api

FulfillmentOrder (shopify.dev)

Or if you just want to use the Order resource api then technically the shipping_address field would be empty for pick up orders - so you can guess from that
