# Publish to social feed

> Publishes an activity item to the public Social Feed. Publishing a PnL card forces its visibility to public. Idempotent per (user, source).



## OpenAPI

````yaml /api-reference/openapi.json post /v1/user/feed
openapi: 3.0.0
info:
  title: Hyperprop Platform API
  version: 1.0.0
  description: >-
    REST API for the Hyperprop Trading Platform — provision evaluation and
    funded trading accounts, manage traders and plans, react to account
    lifecycle events via signed webhooks, and reconcile billing. Built for prop
    firms integrating from their own backend.


    ## Authentication


    Two methods, depending on who is calling:


    ### Bearer Token (JWT) — users & dashboard

    Most endpoints accept a JWT via `Authorization: Bearer <token>`. Used by the
    dashboard and client applications.


    ### API Key — organizations (prop firms)

    Organization endpoints also accept `X-API-Key: hp_live_...` for programmatic
    access from your backend — no browser session needed. Keys are managed by
    organization admins in the dashboard; each key carries permissions (`read`,
    `write`, `admin`) and can be rotated or revoked at any time. Keys are stored
    hashed (SHA-256) — the raw key is shown once at creation. Endpoints that
    create or modify data require `write` or `admin`.


    ## Quick Start


    ```bash

    # 1. List your trading plans (grab a tradingPlanId)

    curl "https://api.hyperprop.com/platform/v1/organization/trading-plans" \
      -H "X-API-Key: hp_live_your_key_here"

    # 2. Create a trading account for a trader (by Hyperprop user ID or email)

    curl -X POST
    "https://api.hyperprop.com/platform/v1/organization/trading-accounts" \
      -H "X-API-Key: hp_live_your_key_here" \
      -H "Content-Type: application/json" \
      -d '{"type": "evaluation", "tradingPlanId": "<uuid>", "email": "trader@example.com"}'
    ```


    ## Response Envelope & Error Handling


    **Success** responses always wrap the payload:


    ```json

    { "success": true, "data": { ... }, "message": "optional human-readable
    note" }

    ```


    **Errors** — including request-validation failures, auth failures, and
    errors

    proxied from the trade engine — always return this single uniform shape with
    a

    machine-readable `code` you can switch on:


    ```json

    {
      "success": false,
      "statusCode": 404,
      "error": "Not Found",
      "message": "No Hyperprop user found with that email. The trader must have a Hyperprop account before an account can be created for them.",
      "code": "TRADER_NOT_FOUND"
    }

    ```


    Parse rule of thumb: check `success`; on `false`, switch on `code` (never on
    `message` text — messages can be reworded). Some errors carry additional
    structured context alongside these fields (e.g. payout rejections include a
    `consistency` block).


    Common codes: `VALIDATION_ERROR` (malformed payload/params), `UNAUTHORIZED`,
    `INSUFFICIENT_PERMISSIONS` / `NOT_ADMIN` (key lacks write/admin),
    `*_NOT_FOUND` (missing resource), `*_NOT_IN_ORG` (resource belongs to
    another organization), `IDEMPOTENCY_KEY_IN_PROGRESS` (duplicate in flight),
    `ENGINE_UNREACHABLE` (trade engine down — retry with the same idempotency
    key). Endpoint-specific codes (e.g. payout `OPEN_EXPOSURE`,
    `CONSISTENCY_BLOCKED`) are documented on each endpoint.


    ## Idempotency


    **Every mutating endpoint (POST, PUT, PATCH, DELETE) honors idempotency keys
    uniformly.** Send an `Idempotency-Key` header (the `X-Idempotency-Key`
    spelling is accepted as an alias) to retry any write safely without creating
    duplicates.


    How it works:


    - The key is scoped to your organization + the request path. The first
    request with a given key executes normally and its response is cached for
    **24 hours**.

    - A replay (same key, same path) within 24 hours returns the cached response
    with an `Idempotency-Replayed: true` response header — the operation is
    **not** executed again.

    - If a request with the same key is still in flight, the duplicate gets `409
    IDEMPOTENCY_KEY_IN_PROGRESS` — back off and retry; you'll then receive the
    cached response.

    - 5xx responses are **not** cached, so retrying after a server error
    re-executes the request (that's what you want). 2xx-4xx responses are cached
    — if a request failed validation and you fix the payload, use a **fresh
    key**.

    - Keys are free-form strings up to 255 characters. Use something that
    identifies the operation on your side, e.g. `order-8814-attempt-1`.


    ```bash

    curl -X POST
    "https://api.hyperprop.com/platform/v1/organization/trading-accounts" \
      -H "X-API-Key: hp_live_your_key_here" \
      -H "Idempotency-Key: order-8814-attempt-1" \
      -H "Content-Type: application/json" \
      -d '{"type": "evaluation", "tradingPlanId": "...", "traderId": "..."}'
    ```


    This applies to account creation, account PATCH (status, currentBalance,
    metadata), rules, plans, lockouts, payouts, team, webhooks — every write on
    the platform API. Payouts additionally forward the key to the trade engine
    for engine-level double-withdrawal protection.


    ## Pagination & Sorting


    List endpoints support both styles:


    - **Cursor (recommended):** pass `?cursor=` from the previous response's
    `pagination.nextCursor`. Stable under concurrent writes.

    - **Offset:** `?limit=&offset=` with `pagination.total` / `hasMore` in the
    response.


    Sorting uses `?sort=field:direction` (e.g. `?sort=created_at:asc`); allowed
    fields are listed per endpoint. Default: `created_at:desc`.


    ## Custom Metadata


    Trading accounts, purchases, traders, plans, and rules all carry a free-form
    `metadata` JSON object. Use it to store your own references — payment IDs,
    campaign tags, payout records, internal notes. Hyperprop stores and returns
    it verbatim (and lets you filter list endpoints by it, e.g.
    `?metadata=stripePaymentId:pi_123`) but never interprets it. Update
    endpoints support `mergeMetadata: true` for shallow (top-level) merges
    instead of wholesale replacement.


    ## Webhooks


    Subscribe to account lifecycle events (`account.created`,
    `account.status_changed`, `account.updated`, `account.passed`,
    `account.failed`, and more) via the Webhooks endpoints. Deliveries are
    HMAC-SHA256 signed — verify `X-Hyperprop-Signature` with your endpoint
    secret, using `X-Hyperprop-Timestamp` for replay protection;
    `X-Hyperprop-Delivery` gives you a unique delivery ID for deduplication.
    Failed deliveries are retried with backoff, and you can redeliver any event
    from the dashboard or API.


    ## MCP Connector (AI Agents)


    The platform ships a built-in [MCP](https://modelcontextprotocol.io) server,
    so AI agents and assistants (Claude, Cursor, custom agents) can operate your
    organization directly — no integration code required.


    ```http

    Endpoint:  POST https://api.hyperprop.com/platform/v1/mcp

    Transport: Streamable HTTP (stateless, JSON responses)

    Auth:      X-API-Key header, Authorization: Bearer hp_live_..., or OAuth

    ```


    **Claude web / desktop (Add custom connector):** paste the endpoint URL and
    leave the OAuth Client ID/Secret fields empty — the connector registers
    itself automatically. Claude opens a Hyperprop consent page where an org
    admin pastes the organization API key once; access then follows that key's
    permissions and ends if the key is revoked. (Under the hood: OAuth 2.1 with
    PKCE and dynamic client registration.)


    **Cursor / Claude Code — `mcp.json`:**


    ```json

    {
      "mcpServers": {
        "hyperprop": {
          "url": "https://api.hyperprop.com/platform/v1/mcp",
          "headers": { "X-API-Key": "hp_live_your_key_here" }
        }
      }
    }

    ```


    **Available tools (12):** `list_trading_plans`, `list_trading_accounts`,
    `get_trading_account`, `get_account_audit_log`, `list_traders`,
    `get_trader`, `list_purchases`, `get_purchase`, `get_billing_summary` (read)
    · `create_trading_account`, `update_trading_account`, `record_payout`
    (write).


    Every tool call executes the corresponding REST endpoint with your key, so
    organization scoping, permissions, validation, audit logging, and webhooks
    apply exactly as documented on each endpoint. Read tools work with any key;
    write tools need `write`/`admin` permission — connect a **read-only key** if
    you want a strictly read-only agent. `create_trading_account` accepts an
    optional `idempotencyKey` so agent retries can't create duplicates, and
    `record_payout` implements the documented payout recipe (append to
    `metadata.payouts`, adjust `currentBalance`, audit-logged `reason`).


    ## Endpoint Groups


    - **Authentication** — Sign up, sign in, OAuth, MFA, password reset. No auth
    required for most.

    - **User** — Profile, notifications, demo accounts, audit logs. Requires
    **Bearer token** (JWT).

    - **Organization** — Trading accounts, plans, rules, traders, purchases,
    lockouts, billing, bulk operations, webhooks, analytics. Accepts **Bearer
    token** OR **API Key**.

    - **System** — Health checks. No auth required.
