Note: This library is not official from Adyen. Note: This plugin is forked from the plugin "flutter_adyen"
Flutter plugin to integrate with the Android and iOS libraries of Adyen. This library enables you to open the Drop-in method of Adyen with just calling one function.
This should support One time payment and recurring payment.
Before calling the plugin, make sure to get the payment methods from Adyen or better from your backend. For this, call the a /paymentMethods endpoint:
POST: https://checkout-test.adyen.com/v46/paymentMethods // Version number might be different Payload should contain the merchant account
{
"merchantAccount": "<YOUR ACCOUNT>"
}
Append your API key and a content-type to the headers:
Content-Type: application/json
X-API-KEY: AQEXXXXXXXXXXXXXXXX
It's not recommended to store the API key in the front-end for security reasons!
####You also need to have the:
- publicKey (from Adyen)
- merchantAccount (from Adyen)
- amount & currency
- shopperReference (e.g userId)
- reference (e.g transactionId)
##Setup
###Android Add this in your android/build.gradle
implementation "com.adyen.checkout:drop-in:3.2.1"
And in the AndroidManifest.xml in your application tag add this service, this allows adyen to tell the android app the result of the payment.
<application ...>
...
<service
android:name="app.startselect.flutter_adyen_drop_in.MyDropInService"
android:permission="android.permission.BIND_JOB_SERVICE" />
</application>
you also might need to set minifyEnabled & useProguard to false if it crashes on a release build
buildTypes {
release {
signingConfig signingConfigs.release
minifyEnabled false
useProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
###iOS You need to add a URL_SCHEME if you do not have one yet.
You might need to run this command pod update Adyen/Card
in your ios folder.
##Usage Just add this in your dart code
const PAYMENT_SUCCESS = 'SUCCESS';
const PAYMENT_CANCELLED = 'CANCELLED';
String dropInResponse = await FlutterAdyen.openDropIn(
paymentMethods: jsonEncode(examplePaymentMethods),
baseUrl: 'https://YOURBACKEND/payment/',
authToken: 'Bearer AAABBBCCCDDD222111',
merchantAccount: 'YOURMERCHANTACCOUNTCOM',
publicKey: pubKey,
amount: '1230',
currency: 'EUR',
iosReturnUrl: 'YOURAPP://' <-- URL_SCHEME_FOR_YOUR_iOS_APP
shopperReference: DateTime.now().millisecondsSinceEpoch.toString(),
reference: DateTime.now().millisecondsSinceEpoch.toString(),
);
if(dropInResponse == 'PAYMENT_SUCCESS') ...
if(dropInResponse == 'PAYMENT_CANCELLED') ...
else ... // you will get the error message here. (It is not translated to any languages)
The library expect your backend to provide the following endpoints as documented by Adyen:
