I have been searching for a way to do this all day. I have found posts mentioning it but have not found one that works. I have an API that needs Authentication. I Know how to do it in classic but because I need a Cross-Platform App I Have been trying to use X. Classic Example: ![Screenshot_2019-07-19%20MIT%20App%20Inventor](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/a/1/a1ff84972a3e298ea93653abb2c6c67712b55b5d.png) Users enter their Username and Password and I have an API that I made that will return base64. So Now I need to send the base64 that is sent back from the first API. @domhnallohanlon @Conor ---
