I just tried it with the Airtable API:
If you use Custom Actions to get multiple items and add an action to save the result to a collection, Adalo can only handle ONE record.
So it looks like it is currently designed to handel single records only.
To fetch multiple records you need to use External Collections.
In your case:
The API must have the ability to pass a query parameter that you can filter for a certain card.
Unfortunately we don’t have Magic Text available to have flexible Endpoints for External Collections.
