Creates a Debtor resource.

This endpoint creates a debtor. A debtor holds the personal and contact information for a debtor_number and is required before collection orders can be synced for that debtor via POST /v3/collection_orders/sync. When a debtor already exists for the given debtor_number, the endpoint responds with 422 - use PATCH /v3/debtors/{debtor_number} to update it instead. The debtor's contact information is also propagated to collection orders that are already running for this debtor. ### 1.
