# Retry Outbound SMS

> Re-queues a failed outbound SMS record for another delivery attempt.
To avoid duplicate message dispatch, the operation is blocked and returns a `409` conflict if the SMS is not currently in a failed state (e.g. already sent or sending).

openapi: 3.1.0
info:
  title: OwnPay Brand Administrative API
  description: >
    The OwnPay Administrative API is used by per-merchant/brand administrators
    to configure and audit their gateway components.

    It exposes endpoints under `/api/admin/v1` to manage regex-based SMS parsing
    templates, inspect and retry failed messages in the outbound SMS
    communication queue, list/revoke paired companion devices, and verify
    white-labeled custom domains.


    ### Authentication

    Administrative endpoints require Bearer authentication using an API key
    generated with the `admin` privilege scope.

    ```http

    Authorization: Bearer <admin_api_key>

    ```

    All actions executed via this API are strictly isolated and scoped to the
    brand/merchant associated with the provided credentials.

    Note that administrative API routes are protected and are **only**
    accessible on the master domain configured via the `APP_DOMAIN` environment
    variable (e.g. `ownpay.org`), and are blocked on custom brand domains.
