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==
