To verify a receipt

iOS

  var ziap_verifier = require('@zentertain/ziap_verifier');

  var verifier = ziap_verifier.createVerifier('ios');
  var payment = { receipt: 'receipt string' };
  verifier.verify(payment, function(error, valid) {
    if (error) {
      // Some error happened, check the error list in lib/errors.coffee
    }

    if (valid) {
      // the receipt is verified as valid
    }
  });

Google Play

  var ziap_verifier = require('@zentertain/ziap_verifier');

  var verifier = ziap_verifier.createVerifier('googleplay', { publicKey: 'The public key' });
  var payment = { receipt: 'receipt string', receiptSignature: 'receipt signature string' };
  verifier.verify(payment, function(error, valid) {
    if (error) {
      // Some error happened, check the error list in lib/errors.coffee
    }

    if (valid) {
      // the receipt is verified as valid
    }
  });

Amazon

  var ziap_verifier = require('@zentertain/ziap_verifier');

  var verifier = ziap_verifier.createVerifier('amazon', { secret: 'The secret string', version: '2' });
  var payment = { userId: 'user_id', receipt: 'receipt' };
  verifier.verify(payment, function(error, valid) {
    if (error) {
      // Some error happened, check the error list in lib/errors.coffee
    }

    if (valid) {
      // the receipt is verified as valid
    }
  });

Facebook

  var ziap_verifier = require('@zentertain/ziap_verifier');

  var verifier = ziap_verifier.createVerifier('facebook', { secret: 'The secret string' });
  var payment = { receipt: 'receipt string', receiptSignature: 'receipt signature string' };
  verifier.verify(payment, function(error, valid) {
    if (error) {
      // Some error happened, check the error list in lib/errors.coffee
    }

    if (valid) {
      // the receipt is verified as valid
    }
  });

If you want a promise

Just add 'P' as suffix to your calls, take amazon's as an example:

  var ziap_verifier = require('@zentertain/ziap_verifier');

  var verifier = ziap_verifier.createVerifierP('amazon', { secret: 'The secret string', version: '2' });
  var payment = { userId: 'user_id', receipt: 'receipt' };
  verifier.verifyP(payment).then(function(valid) {
    if (valid) {
      // the receipt is verified as valid
    }
  }).catch(function(e) {
    // Some error happened.
  }).done();
