I have an API endpoint that I am trying to test with the google app: \'Postman\'. I need to set the headers which use \'Basic authentication\'. I am not sure what should go
Looks like you are facing trouble in getting the base64 value. Well you can make use of in-built function in Javscript as below.
Simply run below code in any JS runtime, (Simplest would be - open console tab in chrome developer tool)
"username:password!" // Here I used basic Auth string format
// Encode the plain string to base64
btoa("username:password!"); // output: "dXNlcm5hbWU6cGFzc3dvcmQh"
// Decode the base64 to plain string
atob("dXNlcm5hbWU6cGFzc3dvcmQh"); // output: "username:password!"
