Got it, thank you for sharing that! If it’s possible in Postman/similar services, it should be possible in Retool. I think our next step is to recreate the working external query as closely as possible in Retool (even if that means hardcoding certain values). Would it be alright if I stepped into your app to try a few configurations? If so, DMing me a link to your app would be perfect. If not, no worries at all! We can work together here
