Getting Started

 IHydroAuthenticator hydroAuthenticator = new HydroAuthenticator("API_KEY", "API_USERNAME", "USE_TESTNET true/false");

Step 1: Add address to whitelist ( be careful, for security purposes, this id will only be generated one time. )

Whitelist whitelist = hydroAuthenticator.whitelist("Hydro/Ethereum ADDRESS 0x12312..."); 

whitelist.isSuccess(); //api call is success (200)
whitelist.getMessage(); //error response content

whitelist.getHydroAddressId(); //get address id

Step 2: Get Raindrop details

Challenge challenge = hydroAuthenticator.challenge("HYDRO_ADDRESS_ID");

whitelist.isSuccess(); //api call is success (200)
whitelist.getMessage(); //error response content

// Set quantity of Hydro tokens to send to the blockchain. Since our token has 18 decimal places, the number that you will need to send may seem large, but remember that the 18 rightmost digits are actually decimals. For example, 313823208533000000 is actually .313823208533000000 Hydro.
challenge.getAmount();

// Randomly generated string used to confirm the validity of the transaction. Only the client requesting the challenge will know the value.
challenge.getChallenge(); 

// The ID assigned to your firm which will be the same for all authentication requests.
challenge.getPartnerId();  

Step 3: Check on exist valid Raindrop transaction

Authenticate authenticate = hydroAuthenticator.authenticate("HYDRO_ADDRESS_ID");

// check is authenticated
authenticate.isAuthenticated();
