Posting with WebSocket API: "A29: Post message did not contain permission data."

Hi, I'm trying the "Posting" capabilities of the WebSockets API. However, I keep getting the following error:

    "NakCode": "AccessDenied",
    "Text": "A29: Post message did not contain permission data.",

My post message is:

{
  "Ack": true,
  "Domain": "MarketPrice",
  "ID": 2,
  "Message": {
    "Domain": "MarketPrice",
    "Fields": {
      "ASK": 45.57,
      "BID": 45.55,
    },
    "ID": 0,
    "Type": "Update"
  },
  "PostID": 1,
  "PostUserInfo": {
    "Address": "10.XX.XX.XX", 	# My IP address
    "UserID": 5555		# Not sure what to use here?
  },
  "Type": "Post"
}

I'm following the documentation at:

Implementing Elektron API applications to work with ATS

Your help is very much appreciated!

Hi @Joris H.

Please refer to the following two posts which contain relevant information - one is specific to Websocket, the other is for a different API.

https://community.developers.refinitiv.com/questions/35300/websocket-contribution-to-an-ats-which-use-peppe-p.html

https://community.developers.refinitiv.com/questions/26611/contribution-fails-to-ric-in-a-containerbu-on-ats.html

So, you will need to check the entitlement requirements with your Market Data team / ATS Admnistrator and then encode a PermData value in your PostMsg as described in the first post above.
