Import RNGoSell from tap-checkout-sdk-react-native package.
` javascript
import RNGoSell from 'tap-checkout-sdk-react-native';
const {
Languages,
PaymentTypes,
AllowedCadTypes,
TrxMode,
SDKMode
}= RNGoSell.goSellSDKModels;
`

Set app credentials using your bundle / package ID and your sandbox and production keys generated by TAP Payments as the below
` javascript
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',
bundleID: (Platform.OS == 'ios') ? 'iOS-PACKAGE-NAME' : 'ANDROIID-PACKAGE-NAME',
}
`

Transaction Modes

` javascript
trxMode: TransactionMode.PURCHASE
`


You can set the transaction mode into one of the following modes:
- Purchase
- `TransactionMode.PURCHASE`

> Normal customer charge.
- Authorize
- `TransactionMode.AUTHORIZE_CAPTURE`

> Only authorization is happening. You should specify an action after successful authorization: either capture the amount or void the charge after specific period of time.
- Save Card
- `TransactionMode.SAVE_CARD`

> Use this mode to save the card of the customer with Tap and use it later.
- Tokenize Card
- `TransactionMode.TOKENIZE_CARD`

> Use this mode if you are willing to perform the charging/authorization manually. The purpose of this mode is only to collect and tokenize card information details of your customer if you don't have PCI compliance certificate but willing to process the payment manually using our services.

Use Tap Pay Button UI
` javascript
render() {
const statusbar =
Platform.OS == 'ios' ? (

) : (

);
const { statusNow } = this.state;
return (


{statusbar}



Status: {statusNow}
{this.state.result}

{Platform.OS == 'ios' ?


Start Payment


:
}



);
}
`
` javascript
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,

marginLeft: '6%',
marginRight: '10%',
},
});

Start Payment

- In your App.js import RNGoSell from 'tap-checkout-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.
` javascript
import RNGoSell from 'tap-checkout-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

`javascript
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]});
})
}

Common Issues

#### iOS
1. Undefined symbol:
1. Undefined symbol: __swift_FORCE_LOAD_$_swiftWebKit
2. Undefined symbol: __swift_FORCE_LOAD_$_swiftUniformTypeIdentifiers
3. Undefined symbol: __swift_FORCE_LOAD_$_swiftCoreMIDI

###### Fix:
- Add `$(SDKROOT)/usr/lib/swift` in Build Settings > Library Search Paths

2. Event Config Error: error
!error-react

###### Fix:
1. In iOS Podfile, replace `use_flipper!` with `use_flipper!({ 'Flipper-Folly' => '2.3.0' })`
2. Use command `pod deintegrate` then remove Podfile.lock
3. Use command `pod install` then `pod update``
