  • New status update search across all of your cases: GET /v1/statusupdates/ returns a single paginated feed of every status update paywise has published to you, instead of paginating each case separately:
    • Overview: what the feed contains, how search and filters combine, and how a result identifies its case
    • Search with q over the status title and the visible text of its description — HTML markup and entities in a rich-text description do not affect matching. The same parameter also matches an event code, exactly and case-insensitively. Search terms need at least three characters.
    • Filter by mandate, reference_number (current or historical, case-insensitive), legal_stage, processing_state, created_after and created_before
    • Results cover main cases and sub-cases. Every row carries the publishing case in mandate and the main case’s reference in reference_number, because sub-cases have no reference number of their own.
    • Ordering is newest first by the business-effective date (custom_date where paywise supplied one, otherwise the creation timestamp), with a stable secondary order so a row never moves between pages. Up to 200 updates per page.
    • Attachment download URLs are unchanged and keep working. Entries in this collection omit file_size, so listing updates never triggers one storage lookup per attachment.
  • No existing endpoint, field or webhook event changed.

August 19

  • New Aktenabrechnungen (per-case statements) endpoints available. An Aktenabrechnung settles exactly one case, alongside the existing statements endpoint, which settles a whole clearing run:
    • Overview: What an Aktenabrechnung is, how it differs from a statement, the sign convention of total_balance, filters and the PDF download
    • List Aktenabrechnungen: List all released per-case statements, filterable by case reference, your own customer number, settlement type and booking date
    • Retrieve an Aktenabrechnung: Retrieve a single per-case statement with its principal claims, VAT breakdown and cost burden
    • The PDF is available at /v1/single-mandate-statements/{id}/download/full-pdf/
  • Two new webhook event types, single_mandate_statement.created and single_mandate_statement.updated, notify you when a per-case settlement is released to you or changes.
  • No existing endpoint, field or webhook event changed.

  • Webhooks are now available. Subscribe to events and receive real-time notifications for changes to your claims, mandates, payments, statements, and requests to client. This allows you to react instantly to updates instead of polling the API:
    • Overview: Introduction, how it works, and a quick example
    • Event Types: Complete list of available event types
    • Signature Verification: HMAC SHA-256 verification with Python, Node.js, and PHP examples
    • Manage Endpoints: API reference for creating, updating, and deleting webhook endpoints, plus test events and delivery inspection
    • Delivery & Retries: Payload format, retry schedule, auto-disable behavior, and best practices

  • New Request to Client endpoints available for handling inquiries from paywise (“Rückfragen”). These endpoints allow you to fully automate the process of receiving and answering questions from paywise during the debt collection process:
    • List requests to client: Get all requests for a mandate, with optional filtering by answered/unanswered status
    • Get request details: Retrieve full details of a specific request including file attachments
    • Submit answer: Submit your response to a request (supports yes/no answers, free text, and file uploads depending on the request type)
    • Upload documents: Attach document files (PDF, JPEG, PNG) to your answer

  • Beta access for the new statements endpoint available. Use it to get full insight into our periodic client statements (“Abrechnungen”) via the API.

October 14

  • New field send_order_confirmation available for the Release Claim for Processing endpoint. This allows you to specify whether or not you want to receive an order confirmation for the claim you submitted. If you submit multiple claims with the same debtor at the same time it is best to only set this flag to true on the last claim to avoid receiving multiple emails.

​
October 10

  • New endpoint info available. This endpoint allows you to get details on the currently used API key in order to test successful authentication.
  • Bugfix: Empty lists on the claims sub objects caused an error on the API. This is fixed now.
