# Update user preferences



## OpenAPI

````yaml patch /v1/user-preferences/{userId}
openapi: 3.1.0
info:
  title: ReconLayer API
  version: 0.1.0
  summary: API-first reconciliation platform with dashboard-optional integration.
  description: >
    ReconLayer is designed to work headlessly.


    The dashboard is one consumer of this API, not the platform boundary.


    Organization resolution currently uses the `x-organization-id` header for
    development.

    In production, the intended model is:


    - dashboard requests authenticate through Clerk and the backend resolves the
    organization from the session

    - headless clients authenticate with API keys mapped to an organization

    - each API key can carry scopes for read/write/export/admin permissions


    Client write endpoints also use request-level idempotency.

    The client must generate an `Idempotency-Key` before the first attempt and

    reuse the same key on every retry of that same request.


    The route structure mirrors the domain:


    - `payment-intents` for expected payments

    - `reconciliation-cases` for reconciliation truth and workflow

    - `webhooks` for provider callbacks

    - `outbound-webhook-*` for client callback subscriptions and delivery
    tracking
