DELTA_SYNC - Partial update on existing case - caseSystemId - empty request payload

Ming

Hi, we would like to perform a re-screen on the same entity by using the https://api.risk.lseg.com/screening/v3/cases/{caseSystemId} endpoint.

The documentation states the following:

DELTA_SYNC: Update; and delta screen the case synchronously against new and updated data from the last screened date. Example: If case was last screened on 01-Feb-2025, using DELTA_SYNC will screen the case against new and updated data since 01-Feb-2025 until the current day. You may also use this option to just perform delta screening on the case without giving any request payload if you do not want to update the case.

we've tried sending over an empty request body but we get a 401 Unauthorized. However, sending the following in the request body with the same entity information works:

{
"caseId": "",
"groupId": "{{group-id}}",
"entityType": "INDIVIDUAL",
"providerTypes": [
"WATCHLIST"
],
"caseScreeningState": {
"WATCHLIST": "INITIAL"
},
"name": "Entity Information",
"nameTransposition": false,
"secondaryFields": [
{
"typeId": "SFCT_5",
"value": "XXX"
},
{
"typeId": "SFCT_3",
"value": "XXX"
}
]
}

is there a reason why we can't leave the request body empty?

Hi @Ming ,

"Thank you for reaching out to us!

We’ve reviewed your question, You can use this option solely for delta screening on the case without including a request payload if you don’t wish to update the case.

This is possible, but please ensure the payload remains empty. Simply use two curly braces like this {} when sending an empty payload for delta screening.

Kindly try this in POSTMAN and let us know if you still see any issues.

Thanks
