Hello @shivammishra , 👋@dennisedson , the call with the values for the foreign id should look like the following:
{"<INDEX OF COLUMN>": [
{
"id": <ID OF ROW OF THE FOREIGN TABLE>,
"type": "foreignid"
}
]}
So the value of the foreign id is an object (array of arrays) because it is a special type of multiselect as I see it. Inside it is the id of the row of the foreign table you selected in your column. If you need any further help don't hesitate to write here.
If my answer was helpful please mark it as a solution.
