After that, you can use the built-in component. Here is a complete example:
import { Component } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable, of } from 'rxjs';
import { switchMap } from 'rxjs/operators';
import { StripeService } from 'ngx-stripe';
import {
StripeElementsOptions,
PaymentRequestPaymentMethodEvent,
PaymentIntent,
PaymentRequestShippingAddressEvent,
} from '@stripe/stripe-js';
@Component({
selector: 'app-payment-request-button',
templateUrl: './payment-request-button.component.html',
})
export class PaymentRequestButtonComponent {
elementsOptions: StripeElementsOptions = {
locale: 'es',
};
paymentRequestOptions = {
country: 'ES',
currency: 'eur',
total: {
label: 'Demo Total',
amount: 1099,
},
requestPayerName: true,
requestPayerEmail: true,
};
constructor(
private http: HttpClient,
private stripeService: StripeService
) {}
onPaymentMethod(ev: PaymentRequestPaymentMethodEvent) {
this.createPaymentIntent()
.pipe(
switchMap((pi) => {
return this.stripeService
.confirmCardPayment(
pi.client_secret,
{ payment_method: ev.paymentMethod.id },
{ handleActions: false }
)
.pipe(
switchMap((confirmResult) => {
if (confirmResult.error) {
// Report to the browser that the payment failed,
// prompting it to re-show the payment interface,
// or show an error message and close the payment.
ev.complete('fail');
return of({
error: new Error('Error Confirming the payment'),
});
} else {
// Report to the browser that the confirmation was
// successful, prompting it to close the browser
// payment method collection interface.
ev.complete('success');
// Let Stripe.js handle the rest of the payment flow.
return this.stripeService.confirmCardPayment(
pi.client_secret
);
}
})
);
})
)
.subscribe((result) => {
if (result.error) {
// The payment failed -- ask your customer for a new payment method.
} else {
// The payment has succeeded.
}
});
}
onShippingAddressChange(ev: PaymentRequestShippingAddressEvent) {
if (ev.shippingAddress.country !== 'US') {
ev.updateWith({ status: 'invalid_shipping_address' });
} else {
// Replace this with your own custom implementation if needed
fetch('/calculateShipping', {
data: JSON.stringify({
shippingAddress: ev.shippingAddress,
}),
} as any)
.then((response) => response.json())
.then((result) =>
ev.updateWith({
status: 'success',
shippingOptions: result.supportedShippingOptions,
})
);
}
}
onNotAvailable() {
// Subscribe to this event in case you want to act
// base on availability
console.log('Payment Request is not Available');
}
createPaymentIntent(): Observable<PaymentIntent> {
// Replace this with your own custom implementation
// to perform a Payment Intent Creation
// You will need your own Server to do that
return this.http.post<PaymentIntent>(
'/create-payment-intent',
{ amount: this.paymentRequestOptions.total.amount }
);
}
}
