List, retrieve, create, and PATCH. A supplied owned collection (addresses, bank accounts, communication channels, legal representatives) replaces that collection completely; omitted collections stay unchanged. A case's debtor is the case's own snapshot (published as `MandateDebtor` without an id) and is not a reusable debtor: it is neither listed nor readable here. ## OpenAPI ````yaml /api-docs/case-management-api/openapi.json get /v2/debtors/ openapi: 3.0.3 info: description: >- Submit orders and manage their complete lifecycle through the current API at the `/v2/` HTTP path. title: paywise Case Management API version: current servers: - description: Production environment url: https://api.paywise.de - description: Sandbox environment url: https://api-sandbox.paywise.de security: [] tags: - description: Submit orders and manage them until acceptance. name: Orders - description: Stable claim resources and their current relationships. name: Claims - description: 'Accepted cases: state, published history and documents.' name: Mandates - description: Debtor master data reused across orders. name: Debtors - description: Payments reported by you and booked by paywise. name: Payments - description: Files attached to claims and other resources. name: Documents - description: Collective statements (Sammelabrechnungen). name: Statements - description: Per-case statements (Aktenabrechnungen). name: Single mandate statements - description: Webhook endpoints and their signing secrets. name: Webhooks - description: Delivery log and redelivery of webhook events. name: Webhook deliveries - description: Ordered feed of the events webhooks deliver. name: Events - description: Reference catalog of legal forms. name: Legal forms - description: The authenticated credential and its context. name: Info - description: Rate-limit headroom of the credential. name: Usage - description: Availability of the API. name: Health externalDocs: url: https://docs.paywise.de/api-docs/case-management-api/introduction paths: /v2/debtors/: get: tags: - Debtors summary: List debtors description: |- The reusable debtors of your company.
