WC1 API V3 ongoing-screening-updates respond "no ogs caces".

satom

Hi there.
I want to get response of the endpoint cases/ongoing-screening-updates. But I couldn't get screening results by OGS screening.

I used WCA API V3.
I called api like bellow.
```
{{protocol}}{{gateway-host}}{{gateway-url}}cases/ongoing-screening-updates

{    "filter": "updateDate=RANGE=(2020-12-06T23:59:59Z,2025-08-20T18:00:00Z); providerType==WATCHLIST",    "mode": "SUMMARY",    "sort": [        {            "columnName": "updateDate",            "order": "ASCENDING"        }    ],    "pagination": {        "itemsPerPage": 100,        "pageReference": null    }}
```

Then I got the 404 notfound error response.

```
{    "id": "04e174fd-9722-416c-b313-6225dbb5bd1c",    "status": "404",    "errors": [        {            "code": "NO_OGS_CASE_UPDATES_FOUND_WITHIN_DATE_RANGE",            "message": "No ogs case updates found within date range."        }    ]}

```

Is this meannig I have no updated results by OGS screening? Or I made a mistake of calling the api?
I checked the WC1 GUI. In case manager, the "Last Screened Date" was updated by the time of OGS screening.
One of them was set "Last Modified Date-OGS:05-Apr-2024 00:16". It means there was results by OGS screening, but It was too old to respond, rigth?
If that is right, how can I get results by OGS screening? (How to create data easy to be checked by OGS screening.)

Thanks,
satom.

Hi @satom ,

Thanks for reaching out to us!

There is no strict recommendation on how or when to fetch ongoing screening (OGS) updates—it entirely depends on your workflow and use case. You can choose to fetch updates using the OGS monitoring endpoint either daily, weekly, or at any other interval that suits your operational needs.

The method you're currently using to fetch updates is correct. However, please note that the OGS monitoring endpoint only returns updates from the last 30 days.

However, In the case you mentioned above, the update is older than 30 days, which is why no results were returned.

In version 3, if there are no updates within the specified date range the system is designed is such a way that the endpoint responds with a 404 error. The response body will include a clear error message: NO_OGS_CASE_UPDATES_FOUND_WITHIN_DATE_RANGE

We recommend capturing and reviewing the error message in the response body to understand the cause of the error code. This will help you determine whether the absence of results is due to the date range or another issue.
