UI Builder

I’m trying to call a 3rd party API and I’m getting the error(s) below. How do I fix this in UI builder?

Access to XMLHttpRequest at ‘https://postman-echo.com/get’ from origin ‘https://drivencats.backendless.app’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

Do you make that request from a web page or from Cloud Code?

From a web page

looks like the 3rd party server doesn’t handle cors requests properly. Your other option is to make that request from an API service

I'll try that. Thanks Mark.
