Hey @chrisgoffinet and welcome to the community! So the way that our REST API resource works is that you add a base URL when you connect the resource, and then add your specific endpoint in the query editor (as you’re building your Retool app). So the workaround here would be to put https://api.upcitemdb.com in as the base URL, and then add prod/trial/lookup in the endpoint field (or whatever makes sense). We add the slash because we’re assuming you’re going to be adding different endpoints for different queries (e.g. /orders for an orders query, /users for a users query), all based off of the same base URL. Does that help / make sense?
