# Report a card found

> Report that the cardholder found a card they had reported lost or stolen.
Dakota clears the report so the card can be used again.

The request has no body. The path names the card.

**The card stays frozen.** This clears the report and nothing else. To
put the card back in service, send `status: active` to
`PATCH /cards/{card_id}` afterwards — which is refused while the report
stands, and succeeds once it is cleared. Two steps deliberately: an
unfreeze re-runs every other check, including the cardholder's state and
the wallet's debt, and a single call that both cleared the report and
opened the card would skip all of them.

A `manual` freeze you applied yourself is untouched, so a card you had
also frozen by hand stays frozen until you lift that too.

**It clears the report whatever set it** — the cardholder's own report
through `POST /cards/{card_id}/lost_stolen_report`, or a dispute you
filed with reason `card_lost` or `card_stolen`. **Any dispute you filed
is untouched:** this moves the card's status, never a claim. It is also
not a fraud re-check — neither this call nor the unfreeze that follows
consults an open dispute, so if you need a claim respected, check it
before calling.

An `overdrawn` card keeps that status and returns to `frozen` rather
than `active` once the debt is paid, which is where the report left it.

**It is safe to repeat.** Reporting a card found that carries no report
returns 200 with the card as it stands, and does nothing. If a request
times out or its response is lost, send it again.

A card belonging to another client is answered with 404, the same as a
card that does not exist.

This endpoint calls the card provider. It is not only a write to
Dakota's own table, so expect network latency.

## OpenAPI

````yaml /openapi.yaml post /cards/{card_id}/found_report
openapi: 3.0.3
info:
  title: Dakota Platform API
  version: 1.0.0
  description: >-
    Combined API specification for Dakota Platform services:

    - Issuance API: Asset minting and burning operations

    - Onboarding API: Know Your Business/Customer verification

    - On/Off Ramp API: Managing on-ramp and off-ramp accounts

    - Recipients API: Managing destinations for KYB'd entities

    - Transactions API: Viewing transaction history across platform operations


    ## Authentication and API Headers


    All API endpoints require the following headers:


    - `X-Idempotency-Key`: Required for all POST endpoints to ensure request
    idempotency

    - `x-api-key`: Required for authentication across all endpoints


    Note: On /applications endpoints you need a token for authentication instead
    of a x-api-key

    - `x-application-token`: Required for authentication on public /applications
    endpoints (alternative to `x-api-key` where documented)



    ## Rate Limits


    Requests are rate limited per API key. Every response includes the following
    headers:


    | Header | Description |

    | --- | --- |

    | `X-RateLimit-Limit` | Maximum requests allowed in the current one-minute
    window. |

    | `X-RateLimit-Remaining` | Requests remaining in the current window. |

    | `X-RateLimit-Reset` | Absolute Unix timestamp (seconds since epoch) when
    the current rate-limit window resets. |


    When a request is throttled (`429`), responses also include `Retry-After`
    with seconds to wait before retrying.

      ### Webhook event catalog (v1)


      Every card-family event a client can subscribe to, in one place:


      | Event | Fires when |

      | -- | -- |

      | `cardholder.created` | A cardholder is created. |

      | `cardholder.updated` | Any cardholder change, including every
      review-status transition and deletion (`status: closed`). |

      | `cardholder.information_requested` | A reviewer asks for more
      information; the payload lists the open requirements. |

      | `card.created` | A card is created. |

      | `card.updated` | Any card change: status, spend limit, last4, freeze
      sources. A close arrives here with `status: closed`. |

      | `card_transaction.created` | The first event for a transaction, normally
      an authorization (`status: authorized`) placing a hold. A declined
      authorization also arrives here, with `status: declined`. |

      | `card_transaction.updated` | Every later change to the same transaction
      (see below). |

      | `wallet.card_enablement.completed` | A wallet's card-settlement
      enablement became active. |


      **Card event ordering.** `card.created` and `card.updated` carry the card
      as it stands after

      the change, including `version` and `freeze_sources` (always an array,
      empty when nothing

      holds the card). `version` is strictly increasing per card and matches the
      `version` on the

      card resource. Deliveries can arrive out of order, so keep the highest
      `version` you have

      applied for each card and drop any event whose `version` is not greater
      than it.


      **One transaction stream.** Holds, releases, partial clearings,
      settlement, returns,

      disputes and force posts are not separate event types. They are `status`
      transitions on

      the transaction, delivered as `card_transaction.updated` with the same
      payload shape as

      `card_transaction.created`:


      | What happened | `status` on the event |

      | -- | -- |

      | Transaction known before its first authorization event | `pending` (on
      `card_transaction.created`) |

      | Hold placed (authorization) | `authorized` (on
      `card_transaction.created`, or `card_transaction.updated` after a
      `pending` start) |

      | Hold released without clearing (merchant, issuer or network reversal) |
      `auth_reversed` |

      | Hold expired unused | `expired` |

      | Part of the hold settled | `partially_cleared` (with the new
      `cleared_amount`) |

      | Fully settled | `cleared` |

      | Settled with no prior hold | `force_posted` |

      | Merchant refund | `returned`, usually on a new card transaction for the
      refund while the original purchase stays `cleared`. A refund can also land
      on the purchase's own transaction, which keeps its purchase status until
      the refunds cover everything that cleared and nothing authorized is left
      to clear. A transaction carries a refund whenever `refund_state` has a
      value, whatever its `status`. `returned_amount` is how much was refunded.
      The network returned the money; read `refund_state` for whether it reached
      the customer's wallet: `pending` while owed, then `paid`; `reversed` when
      every refund was cancelled before payout; `failed` when a payout failed.
      `returned` alone is not proof of payout. |

      | Merchant refund on its own transaction, fully reversed before it is paid
      out | `auth_reversed` on the refund's card transaction, with
      `refund_state: reversed`. The refund is withdrawn; `refund_state` is what
      tells it from a released hold. |

      | Chargeback opened | `disputed` (reserved; not emitted yet) |

      | Authorization refused | `declined` (on `card_transaction.created`, or
      `card_transaction.updated` when the transaction already exists). Moves no
      money; read `decline_reason` and `decline_code` for why. |


      `outstanding_amount` is the part of `cleared_amount` that no authorization
      covered, less any refunds: non-zero after a force post or an over-capture.


      **Naming.** A dotted segment names a sub-resource of the resource before
      it, so

      `wallet.card_enablement.*` is a wallet's card enablement.
      `card_transaction.*` carries an

      underscore because the resource is `card_transactions`, a top-level
      resource, not a

      sub-resource of a card. It is not a typo, and there is no
      `card.transaction.*` family, and

      no separate settlement event: settlement is a `status` on
      `card_transaction.updated`.


      **Two states on a dispute report, and neither derives from the other.**
      `filing_state`

      is how far the automated filing with the provider has got. `state` is the
      Dakota operator

      workflow, where `filed_at_vendor` still means a person filed by hand. A
      successful

      automated filing does not move `state`. Read the one you mean.

            `overdrawn`: The card's wallet owes money after a lost dispute. The
            card declines every

            authorization. It returns to its earlier status when the debt is
            paid. A client cannot

            request this status, and cannot set `active` or `frozen` while the
            card holds it.

            sorted. Empty when nothing is.

            A card is frozen while any source holds it, and lifting one source
            does not lift another. Read this rather than inferring the cause
            from `status`: `status` reports the card's state at the issuer, so
            it says only that the card is frozen, never why.

            `manual` is a freeze applied through this API and is the only source
            a client can lift, by sending `status: active` to this card's PATCH
            endpoint. While any other source is present that request is rejected
            with a `card-freeze-held` problem, because no card-level action will
            clear it.

            `lost_stolen` is the exception that has a remedy: the cardholder
            reported the card lost or stolen, and reporting it found with `POST
            /cards/{card_id}/found_report` clears the report and leaves the card
            frozen. The ordinary unfreeze works after that.

            A stable, machine-readable code for why the request was refused,

            present only when Dakota has a typed reason for this error. Branch

            on `reason` rather than parsing `detail`.


            When `reason` is a value from the table below other than

            `signature_required` and `immutable_field`, `detail` is text Dakota

            writes for that reason, never a partner's or a bank's wording. For

            those two, `detail` is the text written for that specific refusal.

            In every case the wording can change, so do not parse it.


            This is an open set: new values are added over time and a value is

            never repurposed, so treat an unrecognized `reason` as absent.


            Which operations return it today:


            - `createAccount` (onramp, offramp and swap) and `createTransaction`
              (a one-off transaction creates an account): every value in the
              table except `immutable_field`; `signature_required` comes from
              `createTransaction` only.
            - `updateAccount`: `field_invalid` (a developer fee that is out of
              range), `resource_not_found`, and `immutable_field` (the change
              would alter the account's routing; create a new account instead).
            - `deleteAccount`: `resource_not_found`.

            - `createInstructions`: a payment-agent instruction that creates an
              account fails with the same `reason` values as `createAccount`,
              but `params.field` is never returned there: the response carries
              the other `params` keys only, because this operation has no
              public field names to map to.
            - Other operations may also set `reason`. Treat a `reason` you do
              not recognize as absent, as above, and never assume an operation
              that is not listed here omits it.

    CardFreezeSource:

      title: Card Freeze Source
      description: >-
        What is holding a freeze on a card.


        `manual` is a freeze applied deliberately through this API, and is the
        only source a client can lift.


        `lost_stolen` is a freeze held because the cardholder reported the card
        lost or stolen. A request to set the card `active` while it is held is
        refused. To release it, report the card found with `POST
        /cards/{card_id}/found_report`, which clears the report and leaves the
        card frozen; the ordinary unfreeze works after that.


        This enum grows as new freeze causes are built — a value is added when
        it can actually occur, never before. Treat any value other than
        `manual`, including one your client does not recognise, as a hold no
        card-level request will clear.

            An enrollment flagged during screening takes a longer route:
            `pending` → `under_review` (a reviewer holds it) →
            `request_for_information` (the reviewer needs something from you) →
            `active` or `declined`. You answer information requests through the
            API; there is never a cardholder-facing link. Every transition emits
            `cardholder.updated`, and opening a request also emits
            `cardholder.information_requested`.


            `suspended` and `closed` are lifecycle rather than review states.
            `closed` is terminal and appears only in the `cardholder.updated`
            webhook emitted when a cardholder is deleted — deleted cardholders
            are not returned by the REST endpoints.

        successful (below 400) response. Repeating the same request (same JSON
        body, whatever the key order or

        whitespace) with the same key within that window returns the original
        response with

        `X-Idempotent-Replayed: true` instead of executing the request again.
        Using the same key on the same

        endpoint with a different body returns `422` with problem type
        `idempotency-key-reused`; the request is

        not executed. Error responses (4xx and 5xx) are not remembered, so a
        request refused for a fixable reason

        can be corrected and retried under the same key. Request bodies that are
        not JSON (for example file

        uploads) are not compared.
