alternate field for "processing_method" as the field at ORDER API level is deprecated

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

Hi henryj,
It would be better if we can get a similar field at the order endpoint instead of the order transaction endpoint.
Please advise if there is any such field at REST ORDER API Level
Thanks

Which order transaction field can we use to get the procssing_method info?
At order level, payment_details, processing_method and gateway are deprecated.
