Can't get API Query to work

I’ve got a Bricks Builder API Query, which seems to be working fine. Screenshot here https://cln.sh/F7v4GtqJ

Now, I’m trying to do the exact same thing with Bricksforge, and for the life of me, I can’t get it to work. Screenshot here https://cln.sh/K0v30HN5

I am trying to query the Amelia API endpoint (described here Search timeslots - Amelia WordPress Booking Plugin )

My full endpoint URL as per the resource is {{site_URL}}/wp-admin/admin-ajax.php?action=wpamelia_api&call=/api/v1/search

Then I’m adding authentication as API key with the name Amelia.

Both exactly the same settings. Bricks fetches it fine, but Bricksforge returns → 404: The API request failed because the resource was not found.

Even when I run this URL {{site_URL}}/wp-admin/admin-ajax.php?action=wpamelia_api&call=/api/v1/search through the browser, all seems to be fine.

Any ideas what am I doing wrong?

Cheers
