Create a company in the Fintecture Console. Companies are entities managed through your organisation structure that can be associated with organisation nodes.

When using OAC tokens, incorporation is optional — some entities may not have formal incorporation identifiers (SIREN/VAT/HRB). In this case, provide external_id as the unique business identifier (uniqueness enforced per organisation).

🔒 This endpoint requires an OAC (Organisation Access Credentials — ⚠️ Beta) access token with the companies:write scope.
