Contributions over Websockets - NotEntitled code

Hi,

We are working with Refinitiv (Richard Smith) to create a POC for Contributions (Posting data using Websockets).

We have developed a POC for automatically creating RICs and have created a sample RIC under SAMPLE3=LLAC

We are now trying to post data to that RIC. I have create a sample app in C# that does this but I am getting a NotEntitled code after my Login request.

I have reached out to Refinitiv (Richard Smith) who has advised I create a ticket here.

We successfully authenticate and get back a token, however, the Login seems to be rejected.

Here are the responses:

{{

"access_token": "REMOVED FOR CLARITY",

"refresh_token": "c1126397-cea8-49f4-bf95-0d5c3e78eb2f",

"expires_in": "600",

"scope": "",

"token_type": "Bearer"

}}

I then send a Login request, like:

{"ID":1,

"Domain":"Login",

"Key": {

"NameType": "AuthnToken",

"Elements": {

"ApplicationId": "256",

"Position": "10.0.0.162",

"AuthenticationToken": "REMOVED FOR CLARITY"

}

}

}

And get back a NotEntitled Code:

{{"ID": 1,

"Type": "Status",

"Domain": "Login",

"State": {

"Stream": "Closed",

"Data": "Suspect",

"Code": "NotEntitled",

"Text": "System busy"

},

"Private": true

}

}

I used the following details (from the Python example on Developer Portal):

Auth URL: https://api.refinitiv.com:443/auth/oauth2/v1/token

Host: contrib-ws1-emea1.platform.refinitiv.com => wss://contrib-ws1-emea1.platform.refinitiv.com/WebSocket

Service: DDS_TRCE

AppID: 256

Port: 443

Are these correct or is it permissions on my account?

I wasn't sure about the Service name - where do I find this information?

Thanks

Emir
