goSellSDK should be set up. To set it up, add the following lines of code inside sdkConfigurations.js in your project. Import RNGoSell from @tap-payments/gosell-sdk-react-native package.

import RNGoSell from '@tap-payments/gosell-sdk-react-native';
const {
Languages,
PaymentTypes,
AllowedCadTypes,
TrxMode,
SDKMode,
Listener,
}= RNGoSell.goSellSDKModels;

Set app credentials using your bundle / package ID and your sandbox and production keys generated by TAP Payments as the below

const appCredentials = {
    production_secrete_key: (Platform.OS == 'ios') ? 'iOS-Live-KEY' : 'Android-Live-KEY',
    language: Languages.EN,
    sandbox_secrete_key: (Platform.OS == 'ios') ? 'iOS-SANDBOX-KEY' : 'Android-SANDBOX-KEY',

• New Customer (First time to pay using goSell SDK)

const customer = {
    isdNumber: '965',
    number: '00000000',
    customerId: '',
    first_name: 'test',
    middle_name: 'test',
    last_name: 'test',
    email: '[email protected]',
};

After the first transaction success, you receive the customerId in the response. Save it to be used in the next transaction.

• Existed Customer (paid before using goSell SDK) You need to set the customerId only and you can see the customer saved cards if the user has.

const customer = {
    isdNumber: '965',
    number: '00000000',
    customerId: 'cus_smdnd3346nd3dks3jd9drd7d',
    first_name: '',
    middle_name: '',
    last_name: '',
    email: '',
};

Please note that goSell SDK using the customerId only if it's not Empty ('').

Use Tap Pay Button UI

render() {
    const statusbar =
      Platform.OS == 'ios' ? (
        <StatusBar backgroundColor="blue" barStyle="light-content" />
      ) : (
          <View />
        );
    const { statusNow } = this.state;
    return (
      <SafeAreaView style={styles.safeAreaView}>
        <View style={styles.container}>
          {statusbar}
          <Header title="Plugin Example app" />
          <Text style={styles.statusText}> Status: {statusNow}</Text>
          <Text style={styles.resultText}>{this.state.result}</Text>
          <View style={styles.bottom}>
            {Platform.OS == 'ios' ?
              <TouchableOpacity onPress={this.startSDK}>
                <View style={styles.payButtonBg}>
                  <Text style={styles.payButtonText}>Start Payment</Text>
                </View>
              </TouchableOpacity>
              : <Button onPress={this.startSDK} {...styles.payButtonBg} title='Start Payment' />
            }
          </View>
        </View>
      </SafeAreaView>
    );
  }

Use Charge Id callback

  constructor(props) {
    super(props);
     this.subscription = RNGoSell.goSellListener.addListener(RNGoSell.goSellSDKModels.Listener.paymentInit, (chargeId) => {
      console.log("chargeId", chargeId)
    })
  }

  componentWillUnmount() {
    this.subscription.remove() // to clear the listener
  }

Use apple pay cancel callback

  constructor(props) {
    super(props);
     this.subscription = RNGoSell.goSellListener.addListener(RNGoSell.goSellSDKModels.Listener.applePayCancelled, (result) => {
      console.log("result", result)
    })
  }

  componentWillUnmount() {
    this.subscription.remove() // to clear the listener
  }

const styles = StyleSheet.create({
  safeAreaView: {
    flex: 1,
    backgroundColor: '#000',
  },
  container: {
    flex: 1,
    backgroundColor: '#F5FCFF',
  },
  statusbar: {
    height: 20,
  },
  payButtonBg: {
    alignItems: 'center',
    color: '#25cf1f',
    backgroundColor: '#25cf1f',
    paddingVertical: 12,
    paddingHorizontal: 25,
    borderRadius: 25,
    position: 'absolute',
    bottom: 0,
    width: '90%',
    marginLeft: '6%',
    marginRight: '10%',
  },
  payButtonText: {
    color: '#FFF',
    fontSize: 20,
  },
  bottom: {
    flex: 1,
    justifyContent: 'flex-end',
    marginBottom: 36,
  },
  statusText: {
    textAlign: 'center',
    fontWeight: 'bold',
    fontSize: 25,
  },
  resultText: {
    textAlign: 'center',
    fontSize: 15,
    width: '90%',
    marginLeft: '6%',
    marginRight: '10%',
  },
});

Start Payment

• In your App.js import RNGoSell from '@tap-payments/gosell-sdk-react-native'
• Import sdkConfigurations from './sdkConfigurations'
• Call start payment from

Parameters

• First parameter is the sdkConfigurations dictionary
• Second parameter is integer value to set the termination timeout in milliseconds, the sdk will terminate the session after this time expire. Set 0 if you don't want to terminate the session and keep it terminated normally clicking on cancel button by the user
• Third parameter is the result callback, you can handle the required action on recieving the the result through this callback.

import RNGoSell from '@tap-payments/gosell-sdk-react-native';
import sdkConfigurations from './sdkConfigurations';
// startPayment(sdkConfigurations, terminationTimeoutInMilliseconds, this.handleResult)
// Set terminationTimeoutInMilliseconds to 0 to prevent termination the session automatically
RNGoSell.goSellSDK.startPayment(sdkConfigurations, 0, this.handleResult) 

Handle SDK Result

handleResult(error, status) {
    var myString = JSON.stringify(status);
    console.log('status is ' + status.sdk_result);
    console.log(myString);
    var resultStr = String(status.sdk_result);
    switch (resultStr) {
      case 'SUCCESS':
        this.handleSDKResult(status)
        break
      case 'FAILED':
        this.handleSDKResult(status)
        break
      case "SDK_ERROR":
        console.log('sdk error............');
        console.log(status['sdk_error_code']);
        console.log(status['sdk_error_message']);
        console.log(status['sdk_error_description']);
        console.log('sdk error............');
        break
      case "NOT_IMPLEMENTED":
        break
    }
  }
  
  handleSDKResult(result) {
    console.log('trx_mode::::');
    console.log(result['trx_mode'])
    switch (result['trx_mode']) {
      case "CHARGE":
        console.log('Charge');
        console.log(result);
        this.printSDKResult(result);
        break;

      case "AUTHORIZE":
        this.printSDKResult(result);
        break;

      case "SAVE_CARD":
        this.printSDKResult(result);
        break;

      case "TOKENIZE":
        Object.keys(result).map((key) => {
          console.log(`TOKENIZE \t${key}:\t\t\t${result[key]}`);
        })

        // responseID = tapSDKResult['token'];
        break;
    }
  }

  printSDKResult(result) {
    if (!result) return
    Object.keys(result).map((key) => {
      console.log(`${result['trx_mode']}\t${key}:\t\t\t${result[key]}`);
    })
  }
