      4   Check KYC status of a particular payment target.
      5   Prompts the exchange to inquire with the bank
      6   as to the KYC status of the respective account
      7   and returns the result.
      8 
      9   **Required permission:** ``instances-kyc-read``
     10 
     11   **Request:**
     12 
     13   *Accept*:
     14     The client may specify the desired MIME-type for the result.
     15     Supported are the usual "application/json", but also
     16     "text/plain".
     17 
     18   :query h_wire=H_WIRE: *Optional*. If specified, the KYC check should
     19     return the KYC status only for this wire account. Otherwise, for all wire accounts.
     20   :query exchange_url=URL: *Optional*. If specified, the KYC check should
     21     return the KYC status only for the given exchange. Otherwise, for all exchanges we interacted with.
     22   :query lpt=TARGET: *Optional*.
     23     Specifies what status change we are long-polling for.
     24     Use 1 to wait for the KYC auth transfer (access token available),
     25     2 to wait for an AML investigation to be done,
     26     and 3 to wait for the KYC status to be OK.
     27     If multiple accounts or exchanges match the query,
     28     any account reaching the TARGET state will cause
     29     the response to be returned.
     30     @since protocol **v17**. @deprecated with **v25**, use ``lp_*``-query parameters instead.
     31   :query lp_status=STATUS: *Optional*.
     32     Specifies what status change we are long-polling for.
     33     If specified, the endpoint will only return once the status *matches* the given value.
     34     If multiple accounts or exchanges match the query,
     35     any account reaching the STATUS will cause the response to be returned.
     36     @since protocol **v25**.
     37   :query lp_not_status=STATUS: *Optional*.
     38     Specifies what status change we are long-polling for.
     39     If specified, the endpoint will only return once the status no longer matches the given value.
     40     If multiple accounts or exchanges *no longer matches* the given STATUS
     41     will cause the response to be returned.
     42     @since protocol **v25**.
     43   :query lp_not_etag=ETAG: *Optional*.
     44     Specifies what status change we are long-polling for.
     45     If specified, the endpoint will only return once the returned "Etag"
     46     would differ from the ETAG specified by the client. The "Etag"
     47     is computed over the entire response body, and thus assured to change
     48     whenever any data point in the response changes. This is ideal for
     49     clients that want to learn about any change in the response.  Clients
     50     using this query parameter should probably also set a "If-none-match"
     51     HTTP header so that if the ``timeout_ms`` expires, they can get back
     52     a "304 Not modified" with an empty body if nothing changed.
     53     @since protocol **v25**.
     54   :query timeout_ms=NUMBER: *Optional.*  If specified, the merchant will
     55     wait up to ``timeout_ms`` milliseconds for the exchanges to confirm completion of the KYC process(es).
     56 
     57   **Response:**
     58 
     59   If different exchanges cause different errors when processing
     60   the request, the largest HTTP status code that is applicable
     61   is returned.
     62 
     63   :http:statuscode:`200 Ok`:
     64     The user may be redirected to the provided locations to perform
     65     KYC checks.
     66     The response will be a `MerchantAccountKycRedirectsResponse` object.
     67     Uses this status code and format only since protocol **v17**.
     68   :http:statuscode:`204 No content`:
     69     No possibilities for KYC operations exist.
     70     @since protocol **v25** only returned if this instance has no bank
     71     accounts or no exchanges are configured for the merchant backend.
     72   :http:statuscode:`304 Not modified`:
     73     The ``ETag`` in the response did not change compared to the one
     74     given in the ``If-none-match`` HTTP header specified by the client.
     75     @since protocol **v25**.
     76   :http:statuscode:`400 Bad Request`:
     77     A query parameter is malformed.
     78   :http:statuscode:`401 Unauthorized`:
     79     The request is unauthorized.
     80     Returned with ``TALER_EC_MERCHANT_GENERIC_UNAUTHORIZED``.
     81   :http:statuscode:`404 Not found`:
     82     The instance is unknown to the backend.
     83     Returned with ``TALER_EC_MERCHANT_GENERIC_INSTANCE_UNKNOWN``.
     84   :http:statuscode:`406 Not acceptable`:
     85     The merchant backend could not produce a response in the desired format.
     86   :http:statuscode:`503 Service unavailable`:
     87     The merchant backend is temporarily unable to process the request.
