Trying to use 'Postman' and having trouble setting Basic access authentication Headers

Your header field should look like this:

Header : Authorization

Value : Basic base64('YourOrgName:YourAPIKEY');

You can get the base64 value of your string here:

https://www.base64encode.org/

For example, for my-org-name:123key4api it should be bXktb3JnLW5hbWU6MTIza2V5NGFwaQ==.

The complete header would look like:

Authorization: Basic bXktb3JnLW5hbWU6MTIza2V5NGFwaQ==

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!"

It's 2019 and with Version 6.5.3 we have a separate tab to use different kind of Authentication techniques.

For basic auth you just have to give username and password after selecting "Basic Auth" under Authentication tab
