Tutorial

Note that each function call returns a promise. To charge a customer, remember that you need to follow a 2-step process: First authorize the amount, then create a transaction for the final amount you want to charge.

For authorizing an amount you want to charge:

varkash=require('node-kash')('<Your Server Key>');kash.authorizeAmount('<Customer ID>',amount).then(function(result){// Now use result.authorization_id with either cancelAuthorization() or// createTransaction()console.log(result.authorization_id);}).catch(function(err){if(err.statusCode===410){// Customer needs to relink their bank accountconsole.log(err.error);}elseif(err.statusCode===402){// Customer has insufficient funds and Kash determines we won't be// able to retrieve the amountconsole.log(err.error);}else{// Any other error conditionsconsole.log(err.error);}});

To cancel an authorized amount:

varkash=require('node-kash')('<Your Server Key>');// Using the authorizationId collected from authorizeAmount()kash.cancelAuthorization(authorizationId).then(function(){// Success!}).catch(function(err){// Any other error conditionsconsole.log(err.error);});

To actually charge the customer:

varkash=require('node-kash')('<Your Server Key>');// Using the authorizationId collected from authorizeAmount()kash.createTransaction(authorizationId,amount).then(function(result){// Success!console.log(result.transaction_id);}).catch(function(err){// Any other error conditionsconsole.log(err.error);});

To do refunds:

varkash=require('node-kash')('<Your Server Key>');// Using the transactionId collected from createTransaction()kash.refundTransaction(transactionId,amount).then(function(result){// Success!}).catch(function(err){// Any other error conditionsconsole.log(err.error);});
