Steps
Create a DELEGATE type cardholder for each authorized card user instead of relying on the old business/organization card model
Call Create a card with program.purpose set to COMMERCIAL and is_personalized set to false to issue a non-personalized commercial card
Set cardholder_id to the DELEGATE cardholder's ID, and optionally add up to two more contacts via additional_cardholder_ids for 3D Secure authentication
Remove the legacy issue_to: ORGANISATION and primary_contact_details fields from the request body — they are not part of the 2024-03-31+ schema
Confirm the response no longer returns issue_to or a top-level type field — that information now lives under the program object
Known gotchas
Non-personalized commercial cards support at most three registered contacts total (the primary cardholder plus up to two additional_cardholder_ids) — plan your 3DS contact list before go-live
Mixing legacy fields (issue_to, primary_contact_details) with the new program/is_personalized fields in the same request is not supported post-2024-03-31 — migrate the whole request body, don't partially patch it
This upgrade path is documented specifically for integrations built before 2024-03-31; if integrating fresh, use the current create-cards tutorials directly rather than the legacy-to-new diff guide
