How would you like the data returned? As an array? e.g
{
"data": [
{
"unique_id": 299161
},
{
"unique_id": 299271
},
{
"unique_id": 299347
},
{
"unique_id": 299383
}
]
}
Then you need to supply a response template. If you are wanting a list of “unique_id” properties from the base object then instead of dragging over “unique_id” scroll down the right hand pannel and click “+” in templates.
Add the following to the template:
{
"unique_id": <<unique_id>>
}
Dragging and dropping the “unique_id” property instead of “<<unique_id>>”.
Now save this template and drop it into the original response:
{
"data": [<<drop template here>>]
}
That should hopefully achieve what you want
