It looks like all of your responses have spaces in them. You want FIELD1,FIELD2 after the = with no spaces.
Like this: https://…/?column=FIELD1,FIELD2
You provide no information as to what API you are using. I recommend that you look at the developer documentation for the API you are using to see if it’s possible to even pass multiple values in a query.
My receiving api wants to receive something like
column=FIELD1&column=FIELD2…
The error message its sends me is
{
“error”: 400,
“code”: 3100,
“source”: “Statut,Brief”,
“message”: “Column does not exist”
}
So I guess Adalo sends column=FIELD1,FIELD2
I have found a solution to my issue
TeamDesk has another way to query data without specifying the fields to retrieve: which is to query for ‘VIEWS’ instead of ‘TABLES’.
