@mraffia,

Thanks for providing the details, the request payload that you're passing is incorrect,the format in which it's being passed is incorrect, you need to define the entityType in the payload and it is a mandatory parameter while screening , I am providing a sample payload for your reference to perform screening, also I notice that few request headers are missing there is no "Date" header and the Content-Length is also missing.Please refer the screenshot attached to check the headers needed to perform screening successfully.Custom fields and secondary fields are optional parameters. screeningheaders.png

{
	"groupId": "{
                {group-id}}",
	"entityType": "INDIVIDUAL",
	"providerTypes": ["WATCHLIST"],
	"name": "putin",
	"customFields": [],
	"secondaryFields": []
}

I would need the values of the data being passed and response details to investigate this further,

401 errors occur because the request has failed an authorization check. This can happen for a variety of reasons, such as

a) An invalid or expired API key,

b)An invalid HMAC signature.

c) Request timing issue/problem with the Date header value. The API client should ensure a correctly synchronized clock is used to generate request timestamps.

d)Incorrect JSON payload formation at the customer’s end that can cause them to observe 401 response.

Hi Meeran,

Thanks for info, we made the corrections in the json and in the HTTP headers. We re-syndicated data from SAP PO. It currently fails with the bad request.

Below is the endpoint url and the corresponding JSON request sent.

{

"groupId": "{ {0a3687d0-6855-1ac5-9a2d-dc0b00000cd8}}",

"entityType": "INDIVIDUAL",

"providerTypes": [

{

"element": "WATCHLIST"

}

],

"name": "Putin",

"customFields": [

],

"secondaryFields": [

]

}

@mraffia

Please pass the providerTypes as shown below, you need to remove the element and just pass WATCHLIST. Also kindly remove the double quotes from the custom and secondary fields array and pass them as an empty array.

"providerTypes": ["WATCHLIST"],

"entityType": "INDIVIDUAL",

"providerTypes": [

"WATCHLIST"

],

"name": "putin",

"customFields": [],

"secondaryFields": []

}

@mraffia

Kindly pass the groupId as "groupId": "0a3687d0-6855-1ac5-9a2d-dc0b00000cd8", instead of "groupId": "{
                {0a3687d0-6855-1ac5-9a2d-dc0b00000cd8}}" it should work.

The issue is resolved. The root cause was that a few request parameters were missing while sending the request to World-Check one.
