# Revoke a webhook destination

> Revoke an account webhook destination, stop future delivery attempts and invalidate pending leases while retaining the existing account history.

Revoke an Ultiwrite webhook destination from your approved account using a current dashboard key with read and evidence permissions. The endpoint below uses the [canonical Ultiwrite OpenAPI contract](https://dwsoffshorepartners.com/.well-known/openapi.json). Pending attempts are invalidated and future sends stop; bytes already transmitted cannot be recalled.

Revocation does not change API approval, refund an investigation or issue additional analysis allowance. Revoke and create a new destination to change its URL. [Review delivery and revocation semantics](https://docs.dwsoffshorepartners.com/partner-api/workflow.md#webhook-notifications).

openapi: 3.1.0
info:
  title: Ultiwrite API
  version: '2026-11-01'
  description: >-
    Ultiwrite is operated by DWS Offshore Fund dba Ultiwrite. Ultiwrite examines
    the documents and evidence behind opportunities, organizations,
    counterparties, acquisitions, financings and portfolios, and returns
    released findings: source economics, document integrity, material
    contradictions, unresolved claims and the next diligence move. The API never
    renders an autonomous approve or decline.


    Partner API (dashboard API key or OAuth 2.1): explicitly approved accounts
    submit evidence, continue asynchronous processing and read the released
    report. Polling uses API requests but no additional analysis credits.
    Reports are never assumed to be immediate.


    Provisioned routes authenticate with an admin-issued uw_live_ API key and
    are listed by name only.


    Versioning: the major version is in the path (/api/v1). Within v1, changes
    are additive; a field or operation is removed only after a deprecation
    notice in this document (deprecated: true) and the changelog. Response
    header Ultiwrite-Api-Version identifies the contract revision.


    API access requires an explicit administrator grant, independent of paid
    plan. Monthly and fixed-minute request limits are pooled across every key
    and partner OAuth grant on the account. Every admitted request, including
    polling and authenticated validation errors, uses one request; failed
    authentication and quota denials do not. Analysis credits use the existing
    separate ledger. Exceeding a limit returns 429 with Retry-After.
