The Rapyd Collect API helps facilitate efficient and seamless payment collection processes. It allows businesses to accept customer payments through various payment methods, offering a range of capabilities that enhance the payment collection experience. You can provide instant checkouts for your customers from around the globe, allowing you to access new markets in a highly secure way. Furthermore, businesses handling recurring payments and subscription-based services can easily automate invoice processing and subscription management via the Rapyd Collect API. Rapyd is an API first company to accept, send and hold funds globally.
In this article, you will learn how to leverage the Rapyd API to collect subscription-based payments from a Flutter application. You will learn how to subscribe a user to your service via a hosted checkout page and the Rapyd API.
What Is the Rapyd Collect API?
Receiving payments from customers across the globe can be a headache as you need to handle different currencies, regulations, and payment methods. It's particularly challenging if you're planning to expand into different geographic markets. The Rapyd Collect API integrates a wide variety of payment networks and technologies from around the world into a single platform. The API provides a single place to manage all your payment integration needs while guaranteeing seamless customer payment collection.
The Rapyd API also ensures your customers have a simple and intuitive checkout facilitated by Rapyd's hosted checkout experience. This also means you don't need to spend time building this experience manually. You can generate a payment request, and in return, Rapyd returns a checkout page. The page will collect all the payment details from the customer and present all available payment methods to them. Once the customer is done, Rapyd informs you of the request status via the endpoints you provide. The hosted checkout experience can also collect subscription billing payments worldwide and supports various payment methods, such as debit and credit cards.
Implementing Payments Using the Rapyd API in a Flutter Application
Following this tutorial, you'll integrate a payment solution via the Rapyd Collect API in a Flutter application. You'll build a Flutter app that provides memes as a service. Users can access a few memes and subscribe to a plan to view unlimited memes.
Prerequisites
Before proceeding, you need to have the following:
The Subscription Service
To offer a subscription service, you must first set it up on Rapyd. Before continuing to set up the subscription, please download the Postman collection, install it, and open the Pre-request Script.
If you experience any errors when evaluating the Pre-request Script, replace its contents with the code below, which generates a request signature needed to authorize your requests to the Rapyd API :
var timestamp = (Math.floor(new Date().getTime() / 1000) - 10).toString();
pm.globals.set("rapyd_request_timestamp", timestamp);
var signature_salt = CryptoJS.lib.WordArray.random(12).toString();
pm.globals.set("rapyd_signature_salt", signature_salt);
var body = '';
if (JSON.stringify(request.data) !== '{}' && request.data !== '' && typeof request.data !=='object' ){
body = JSON.stringify(JSON.parse(request.data));
}
var secret = pm.collectionVariables.get('rapyd_secret_key');
var to_sign = request.method.toLowerCase() + request.url.replace('{{base_uri}}','/v1') + signature_salt + timestamp + pm.collectionVariables.get('rapyd_access_key') + secret + body;
var rapyd_signature = CryptoJS.enc.Hex.stringify(CryptoJS.HmacSHA256(to_sign, secret));
rapyd_signature = CryptoJS.enc.Base64.stringify(CryptoJS.enc.Utf8.parse(rapyd_signature));
pm.globals.set("rapyd_signature", rapyd_signature);
Open the Variables section, where you will input the Rapyd access key and secret key and the API endpoint:
With the above configuration on Postman, you can easily make requests to the Rapyd API and carry out the necessary operations.
Create a Product Service
To establish a subscription service in Rapyd, you need to create a product for the type of service you're offering. Open the Create Services API on the Postman collection and input the following JSON code to create a product:
{
"id": "",
"name": "Online Memery Service",
"type": "services",
"active": true,
"description": "Get access to hundreds of Memes online"
}
Please note the product ID from the response for use in the next section.
Create Subscription Plans
A plan defines the pricing structure of your product. A product can have multiple plans, depending on your needs. Use the Create Plan endpoint on the Postman Collection to create a plan, which will be billed monthly and charged in the currency you specify. The billing scheme will be per unit, while the usage type will be licensed. Use the following JSON to create the plan:
{
"currency": "usd",
"amount":"10",
"interval": "month",
"product": "product_xxxxxxxxxxxxxxxxxxxxxx",
"billing_scheme": "per_unit",
"nickname": "Gold Memery Plan",
"usage_type": "licensed"
}
You can create any number of plans. Once you create a plan, you can then integrate the subscription service into your app.
Integrate the Subscription Service into the Flutter App
With the subscription service ready, you can now build the app for your meme-loving users. In this app, users have a quota of fifty memes; if they want to view more, they should subscribe to a plan. To get started, please grab the starter app in this GitHub repository branch and run it. You should see a screen similar to the screenshot below:
Generate a Request Signature
Like the Postman collection, you must generate a request signature to authorize your requests to the Rapyd API endpoint. To facilitate this, open the pubspec.yaml file and add the crypto: package.
In the lib/network folder, create the file rapyd_connection.dart and add the following content:
import 'dart:convert';
import 'dart:math';
import 'package:convert/convert.dart';
import 'package:crypto/crypto.dart';
import 'package:dio/dio.dart';
class RapydConnection {
final Dio dio = Dio(BaseOptions(
connectTimeout: const Duration(seconds: 30),
receiveTimeout: const Duration(seconds: 30),
));
final String baseUrl = 'https://sandboxapi.rapyd.net';
final String secretKey = ''; // The secret key received from Rapyd.
final String accessKey = ''; // The access key received from Rapyd.
RapydConnection() {
dio.options.baseUrl = baseUrl;
}
String _getRandString(int len) {
var values = List<int>.generate(len, (i) => Random.secure().nextInt(256));
return base64Url.encode(values);
}
String _getSignature(String httpMethod, String urlPath, String salt,
String timestamp, String bodyString) {
String sigString = httpMethod +
urlPath +
salt +
timestamp +
accessKey +
secretKey +
bodyString;
Hmac hmac = Hmac(sha256, utf8.encode(secretKey));
Digest digest = hmac.convert(utf8.encode(sigString));
var ss = hex.encode(digest.bytes);
return base64UrlEncode(ss.codeUnits);
}
Map<String, String> _getHeaders(String method, String urlEndpoint,
{String body = ""}) {
String salt = _getRandString(16);
String timestamp = (DateTime.now().toUtc().millisecondsSinceEpoch / 1000)
.round()
.toString();
String signature =
_getSignature(method.toLowerCase(), urlEndpoint, salt, timestamp, body);
return <String, String>{
"access_key": accessKey,
"signature": signature,
"salt": salt,
"timestamp": timestamp,
};
}
Future<Map<String, dynamic>> makeRequest(
String method, String path, String body) async {
print(body);
final headers = _getHeaders(method, path, body: body);
Response response;
if (method == 'get') {
print(baseUrl + path);
response = await dio.get(path, options: Options(headers: headers));
} else if (method == 'put') {
response =
await dio.put(path, data: body, options: Options(headers: headers));
} else if (method == 'delete') {
response = await dio.delete(baseUrl + path,
data: body, options: Options(headers: headers));
} else {
response = await dio.post(baseUrl + path,
data: body, options: Options(headers: headers));
}
print(response);
if (response.statusCode != 200) {
throw Exception('Request failed: ${response.statusCode}');
}
return response.data;
}
}
The above code calculates the request signature by hashing a concatenation of values, including the Rapyd access key, secret key, timestamp, HTTP method, URL path, and the sent body request. The makeRequest function makes all the Rapyd-related API requests.
Add the following line of code to the NetworkConnection file to include the class above.
final RapydConnection rapyd = RapydConnection();
Generate JSON Models
You need to generate JSON models to decode the Rapyd API response data. Open the app_models.dart file and add the code in this file.
Note: The Rapyd API has numerous JSON responses, and manually creating models would be time-consuming. Json to Dart Model automates this and is a useful VS Code extension. Most JSON models in the code above have been redacted for brevity. You can check the Postman responses for the complete data.
Run the command below to generate the JSON models:
dart run build_runner build --delete-conflicting-outputs
Fetch Subscription Plans
You'll now add functions to the app to present users with various plans and ask them to select the country where they are located so Rapyd can present supported Payment methods in that region.
Add the code below to the NetworkConnection class to fetch the plans you created earlier and the countries supported by Rapyd:
Future<List<Country>> getSupportedCountries() async {
try {
final response = await rapyd.makeRequest('get', '/v1/data/countries', '');
return CountryResponse.fromJson(response).data;
} catch (e) {
print(e);
}
return [];
}
Future<List<Plan>> getSubscriptionPlans() async {
try {
final response = await rapyd.makeRequest('get', '/v1/plans', '');
return PlansResponse.fromJson(response).data;
} catch (e) {
print(e);
}
return [];
}
To present the plans and the country to the user for selection, open the home.dart file and replace the _bottomSheet and initState functions in the class _HomeScreenState with the code below:
List<Country> countries = [];
List<Plan> plans = [];
void _bottomSheet(BuildContext context) {
showModalBottomSheet(
barrierColor: Colors.transparent,
isScrollControlled: true,
useSafeArea: true,
elevation: 5,
context: context,
builder: (ctx) => Container(
padding: const EdgeInsets.symmetric(vertical: 8, horizontal: 12),
child: (countries.isEmpty || plans.isEmpty)
? const Center(
child: CircularProgressIndicator(),
)
: SelectPlanScreen(
countries: countries,
plans: plans,
)),
);
}
Future<void> loadSubscriptionPlans() async {
countries = await NetworkConnection().getSupportedCountries();
plans = await NetworkConnection().getSubscriptionPlans();
if (mounted) {
setState(() {});
}
}
@override
void initState() {
super.initState();
refresh();
loadSubscriptionPlans();
}
Create a new file in the lib folder named select_plan_screen.dart and add the following content:
import 'package:flutter/material.dart';
import 'package:rapyd/hosted_checkout_screen.dart';
import 'models/app_models.dart';
class SelectPlanScreen extends StatefulWidget {
final List<Country> countries;
final List<Plan> plans;
const SelectPlanScreen(
{required this.countries, required this.plans, Key? key})
: super(key: key);
@override
State<SelectPlanScreen> createState() => _SelectPlanScreenState();
}
class _SelectPlanScreenState extends State<SelectPlanScreen> {
List<Country> countries = [];
List<Plan> plans = [];
late Plan selectedPlan;
late Country selectedCountry;
final nameController = TextEditingController();
@override
void initState() {
plans = widget.plans;
countries = widget.countries;
selectedCountry = countries.first;
selectedPlan = plans.first;
super.initState();
}
@override
Widget build(BuildContext context) {
return SingleChildScrollView(
child: Column(
mainAxisSize: MainAxisSize.min,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
const Text(
"To Continue Enjoying More Memes, Please Subscribe for a Plan.",
textAlign: TextAlign.center,
style: TextStyle(fontWeight: FontWeight.bold),
),
const SizedBox(
height: 10,
),
const Text(
"Select Country",
textAlign: TextAlign.center,
),
const SizedBox(
height: 10,
),
DropdownButtonFormField<Country>(
value: selectedCountry,
isExpanded: true,
items: countries
.map((e) =>
DropdownMenuItem<Country>(value: e, child: Text(e.name)))
.toList(),
onChanged: (country) {
selectedCountry = country!;
}),
const SizedBox(
height: 10,
),
const Text(
'Provide a name to use the Hosted Checkout method otherwise leave it blank to use the Subscriptions API method',
style: TextStyle(color: Colors.red),
),
const SizedBox(
height: 5,
),
TextFormField(
controller: nameController,
decoration: const InputDecoration(hintText: "Your Name"),
),
const SizedBox(
height: 10,
),
const Text(
"Select Plan",
textAlign: TextAlign.center,
),
const SizedBox(
height: 10,
),
...plans
.map((e) => RadioListTile.adaptive(
title: Text(e.nickname!),
subtitle: Text("${e.currency} ${e.amount}"),
value: e,
groupValue: selectedPlan,
onChanged: (plan) {
setState(() {
selectedPlan = plan!;
});
}))
.toList(),
Center(
child: ElevatedButton.icon(
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => HostedCheckoutScreen(
customerName: nameController.text.trim(),
plan: selectedPlan,
country: selectedCountry,
),
));
},
icon: const Icon(Icons.subscriptions_rounded),
label: Text('Subscribe To ${selectedPlan.nickname}')),
),
],
),
);
}
}
The above file will display some errors related to missing files; you'll add the relevant files in the next sections.
Hosted Checkout Page
A hosted checkout page facilitates collecting payment information from customers interested in subscribing to your service. The hosted page is generated via the Rapyd API, which returns a web page URL the user can open.
You can customize the page displayed to the customer by opening your Rapyd dashboard, navigating to the Settings tab, and selecting the Branding option. Here, you can modify the color theme, the payment methods to be displayed, the company logo, and many other options.
To allow users to open the web page within the app, add the package webview_flutter: ^4.2.3 into your pubspec.yaml file.
You need a product, a plan, and a customer to generate the hosted checkout page. You already created the product and the plan, so now you'll create a customer before continuing to generate the hosted checkout page.
Open the NetworkConnection file and add the following code:
Future<Customer?> createCustomer(
{required String name, Map<String, dynamic>? paymentMethod}) async {
try {
final response = await rapyd.makeRequest('post', '/v1/customers',
jsonEncode({"name": name, "payment_method": paymentMethod}));
return CustomerResponse.fromJson(response).data;
} catch (e) {
print(e);
}
return null;
}
Future<HostedCheckout?> createCheckoutPage(
{required Customer customer,
required Plan plan,
required Country country}) async {
try {
final response = await rapyd.makeRequest(
'post',
'/v1/checkout/subscription',
jsonEncode({
"customer": customer.id,
"billing": "pay_automatically",
"country": country.isoAlpha2,
"subscription_items": [
{"plan": plan.id, "quantity": 1}
]
}));
return HostedCheckoutResponse.fromJson(response).data;
} catch (e) {
print(e);
}
return null;
}
To generate and display the hosted checkout page, create a new file named hosted_checkout_screen.dart in the lib folder and add the following contents:
import 'package:flutter/material.dart';
import 'package:rapyd/network/network_connection.dart';
import 'package:webview_flutter/webview_flutter.dart';
import 'models/app_models.dart';
class HostedCheckoutScreen extends StatefulWidget {
final Plan plan;
final Country country;
final String customerName;
const HostedCheckoutScreen(
{required this.plan,
required this.customerName,
required this.country,
Key? key})
: super(key: key);
@override
State<HostedCheckoutScreen> createState() => _HostedCheckoutScreenState();
}
class _HostedCheckoutScreenState extends State<HostedCheckoutScreen> {
late final WebViewController controller;
HostedCheckout? hostedCheckoutData;
@override
void initState() {
createCustomerAndCreateHostedPage(
widget.customerName, widget.plan, widget.country);
super.initState();
}
Future<void> createCustomerAndCreateHostedPage(
String name, Plan plan, Country country) async {
Customer? customer = await NetworkConnection().createCustomer(name: name);
if (customer != null) {
hostedCheckoutData = await NetworkConnection()
.createCheckoutPage(customer: customer, plan: plan, country: country);
}
if (hostedCheckoutData != null) {
controller = WebViewController()
..setJavaScriptMode(JavaScriptMode.unrestricted)
..setBackgroundColor(const Color(0x00000000))
..setNavigationDelegate(
NavigationDelegate(
onProgress: (int progress) {},
onPageStarted: (String url) {
print(url);
},
onPageFinished: (String url) {},
onWebResourceError: (WebResourceError error) {
print(error);
},
),
)
..loadRequest(Uri.parse(hostedCheckoutData!.redirectUrl!));
}
if (mounted) {
setState(() {});
}
}
@override
void dispose() {
super.dispose();
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text("Hosted Checkout"),
),
body: hostedCheckoutData == null
? const Center(
child: CircularProgressIndicator(),
)
: WebViewWidget(controller: controller),
);
}
}
The code above creates a new customer on the Rapyd platform and then generates a checkout page for the customer to complete payment. Kindly run the app to experience this functionality.
Integrate Rapyd API for Subscription Checkout
You can also create the subscription directly via the Rapyd API. However, you need to collect the payment details from the user and save them against their profile. Each payment method has its own requirements from the user, so make sure to check.
First, you need to check which payment methods Rapyd supports in the country where the user is located and present them to the user.
Open the NetworkConnection file and add the following code:
Future<List<PaymentMethod>> getCountryPaymentMethods(
{required String countryCode, required String currency}) async {
try {
final response = await rapyd.makeRequest(
'get',
'/v1/payment_methods/country?country=$countryCode¤cy=$currency',
'');
return PaymentMethodsResponse.fromJson(response).data;
} catch (e) {
print(e);
}
return [];
}
Future<Subscription?> createPlanSubscription(
{required Customer customer,
required Plan plan,
required Country country}) async {
try {
final response = await rapyd.makeRequest(
'post',
'/v1/payments/subscriptions',
jsonEncode({
"customer": customer.id,
"billing": "pay_automatically",
"country": country.isoAlpha2,
"subscription_items": [
{"plan": plan.id, "quantity": 1}
]
}));
return SubscriptionResponse.fromJson(response).data;
} catch (e) {
print(e);
}
return null;
}
Rapyd returns all available payment methods in a country but not all support subscription payments, so filter them out.
Create a new file in the lib folder named payment_method_screen.dart, which will enable you to present all available payment methods to the user:
import 'package:flutter/material.dart';
import 'package:rapyd/models/app_models.dart';
import 'package:rapyd/network/network_connection.dart';
import 'package:rapyd/plan_checkout_screen.dart';
class PaymentMethodScreen extends StatefulWidget {
final Plan selectedPlan;
final Country selectedCountry;
const PaymentMethodScreen(
{required this.selectedCountry, required this.selectedPlan, Key? key})
: super(key: key);
@override
State<PaymentMethodScreen> createState() => _PaymentMethodScreenState();
}
class _PaymentMethodScreenState extends State<PaymentMethodScreen> {
late final Plan selectedPlan;
late final Country selectedCountry;
String errorText = '';
List<PaymentMethod> paymentMethods = [];
@override
void initState() {
selectedPlan = widget.selectedPlan;
selectedCountry = widget.selectedCountry;
super.initState();
loadPaymentMethods();
}
Future<void> loadPaymentMethods() async {
var paymethods = await NetworkConnection().getCountryPaymentMethods(
countryCode: selectedCountry.isoAlpha2,
currency: selectedCountry.currencyCode);
// Filter unsupported and non-card payment methods
paymentMethods.addAll(paymethods
.where((element) => element.category == 'card')
.where((element) => element.supportsSubscription));
if (mounted) {
setState(() {
if (paymentMethods.isEmpty) {
errorText = "Payment Methods Not Found";
}
});
}
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(selectedPlan.nickname!),
),
body: errorText.isNotEmpty
? Center(
child: Text(errorText),
)
: paymentMethods.isEmpty
? const Center(
child: CircularProgressIndicator(),
)
: ListView.builder(
itemCount: paymentMethods.length,
shrinkWrap: true,
itemBuilder: (context, index) {
PaymentMethod paymentMethodDatum =
paymentMethods.elementAt(index);
return ListTile(
title: Text(paymentMethodDatum.category),
subtitle: Text(paymentMethodDatum.name),
onTap: () {
print(paymentMethodDatum.type);
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => PlanCheckoutScreen(
plan: selectedPlan,
country: selectedCountry,
paymentMethod: paymentMethodDatum)));
},
);
},
),
);
}
}
Check if the user provided a name when selecting a plan, and if they have, navigate to the HostedCheckoutScreen. If the user didn't provide a name, navigate to the PaymentMethodScreen screen built by the code above to utilize the Subscriptions API checkout method. Please update the button in the select_plan_screen.dart file with the code below:
Center(
child: ElevatedButton.icon(
onPressed: () {
// If the name is not empty, use the Hosted Checkout method to subscribe the user
// otherwise use the Subscriptions API method
if (nameController.text.isNotEmpty) {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => HostedCheckoutScreen(
customerName: nameController.text.trim(),
plan: selectedPlan,
country: selectedCountry,
),
));
} else {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => PaymentMethodScreen(
selectedCountry: selectedCountry,
selectedPlan: selectedPlan,
),
));
}
},
icon: const Icon(Icons.subscriptions_rounded),
label: Text('Subscribe To ${selectedPlan.nickname}')),
),
After the user selects their payment method, you must collect the required details. To facilitate this, add the flutter_credit_card: ^3.0.6 package in your pubspec.yaml file.
Once the information is collected, you can create the customer with their payment details and then create a subscription for the service. In the lib folder, create the file plan_checkout_screen.dart file and add the following contents:
import 'package:flutter/material.dart';
import 'package:flutter_credit_card/credit_card_brand.dart';
import 'package:flutter_credit_card/flutter_credit_card.dart';
import 'package:rapyd/models/app_models.dart';
import 'package:rapyd/network/network_connection.dart';
class PlanCheckoutScreen extends StatefulWidget {
final Plan plan;
final Country country;
final PaymentMethod paymentMethod;

}
}
}
},

);
}
}
