Hey @Sebastian, welcome to the Baserow community!
It’s possible to combine two
link_row_has filters via the query parameters in your API request. It seems that you provide an
b as value, but this must be a numeric value representing the ID of the related row, which must be present as relationship as link row field value. It’s not yet possible to filter based on the value of the primary field in the related table.
Doing something like for the field should work:
Alternatively, it can also be two different fields like so:
In this case the
1 represents the ID of the related row that much be present in the link row value. The ID of the row can be found in the left of a row.
