Hi Shopify Team,
The processing_method field at the Order API level is deprecated.
Reference changelog:https://shopify.dev/changelog/payment-properties-deprecation-on-the-admin-api-order-resource
we want a similar field that helps us in identifying how the payment is processed while placing the order as this field is being used in most of the places in our integration App.
So, requesting you provide a substitute for the processing_method field at the REST order API level.
Appreciate for your quick response
Thanks
