Newbie attempting to get App Access Token from WeWeb front-end

Hi all. Brand new user, using no-code tools WeWeb (front-end) and Xano (back-end) to build a web app. I have the Postman collection setup and am able to call successfully using my credentials in Postman, but getting an ‘Missing or Invalid Authorization Header’ error back from Dwolla in WeWeb. See Loom for details. Can’t figure out what I’m doing wrong in WeWeb. Do I need all the headers that are in Postman? I’ve only added the Authorization header so far. Thanks!

Hi @dorian , Apologies for missing your post! I’m not familiar with WeWeb unfortunately, however is there a way to change the default Content-Type header from application/json to application/x-www-form-urlencoded?
