Today i am working on a batch operation registering several sensors on IBM Watson IoT.
Using curl you need to encode de API KEY and API TOKEN
It easy using the MAC terminal console
To encode just type on terminal: echo -n ‘user:password’ | base64
the result is —> dXNlcjpwYXNzd29yZA==
To decode just type: echo ‘dXNlcjpwYXNzd29yZA==’ | base64 -D
the result is —> user:password
