1. Test your credentials on sandbox environment
curl 'https://sandbox.api.printoclock.com/login_check' -H 'Content-Type: application/json' -X POST -d '{"username":"yourusername","password":"yourpassword"}'
That should return you the token to use in all your future API calls.
2. Write the rest of the step by step tutorial :)
TODO
Checkout our demo code, that’s still the best option to understand how everything works.
