There are two options that can be considered for the business layer to call from the Invocable Method:

• Call the NPS Service with the future annotation.
• Call the NPS Service from a batchable apex class.

I added both classes with test classes.

Limitations-Possible problems:

• The running user must have the corresponding Invocable Apex class security set in their user profile or permission set.
• Callout limits per transaction must be considered.(Which is maximum of 100 in this case)
• The default timeout is 10 seconds. Increasing the timeout can be considered.
• NPS Api allows sending up to 30 Orders at once. This limit definitely should considered.
• A custom checkbox field can be added to the Order object to identify synced orders.
• Email Apex Action can be invoked on the flow to inform admin users.
