Custom Lookup Field in Create Ticket

I Created a Custom Lookup Field named RelatedTicket.
I use the powerautomation connector.
I call the action create ticket where I want in the custom field to give a value. So my Jsn is:

{
"RelatedTicket":ID
}

Where ID is the list item ID of the related ticket. But this gives me an error and the action is not executed.
Any idea?
Thx

Hello! If the RelatedTicket column receives a single value, then you should append Id to the field name and pass an integer which is the list item ID:

{
    "RelatedTicketId": 1
}

For lookup fields with multiple values, you should use the following object:

{
  "RelatedTickestId": {
    "__metadata": {
      "type": "Collection(Edm.Int32)"
    },
    "results": [
      1,
      2
    ]
  }
}

The results property contains the array with list item IDs.

Note! This is a temporary solution for the lookup fields with multiple values. We are going to implement the following approach:

{
  "RelatedTickestId": [
    1,
    2,
  ]
}

But there is no deadline for its implementation so when the temporary solution stops working, the second one will begin to work.
