# or
$ yarn  add  flutterwave-angular-v3

Initialization

Import FlutterwaveModule to the app root module

import { FlutterwaveModule } from "flutterwave-angular-v3"

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FlutterwaveModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})

NB: If you experience compilation errors in your app after importing the Flutterwave module, component or service. Kindly include the following line in tsconfig.app.json under compilerOptions :

paths": { "@angular/*": [ "node_modules/@angular/*" ] }

Then restart server and try again

Usage

Add Flutterwave to your project as a component or directly in your code:

1. As a Component
2. Directly in your code
3. Recurring Payments

Using Flutterwave as a Component

Method 1

Pass in payment parameters individually as component attributes.

import { Component, OnInit } from "@angular/core";
import {
  FlutterwaveService,
  InlinePaymentOptions,
  PaymentSuccessResponse,
} from "flutterwave-angular-v3";
@Component({
  selector: "app-root",
  template: ` <flutterwave-make-payment
    [public_key]="publicKey"
    amount="10"
    currency="NGN"
    payment_options="card"
    redirect_url=""
    text="Pay Now"
    [customer]="customerDetails"
    [customizations]="customizations"
    [meta]="meta"
    [tx_ref]="generateReference()"
    (callback)="makePaymentCallback($event)"
    (close)="closedPaymentModal()"
  >
  </flutterwave-make-payment>`,
})
export class AppComponent {
  //use your PUBLIC_KEY here
  publicKey = "FLWPUBK_TEST-XXXXX-X";

  customerDetails = {
    name: "Demo Customer  Name",
    email: "[email protected]",
    phone_number: "08100000000",
  };

  customizations = {
    title: "Customization Title",
    description: "Customization Description",
    logo: "https://flutterwave.com/images/logo-colored.svg",
  };

  meta = { counsumer_id: "7898", consumer_mac: "kjs9s8ss7dd" };

  constructor(private flutterwaveService: FlutterwaveService) {}

  makePaymentCallback(response: PaymentSuccessResponse): void {
    console.log("Pay", response);
    this.flutterwaveService.closePaymentModal(5);
  }
  closedPaymentModal(): void {
    console.log("payment is closed");
  }
  generateReference(): string {
    let date = new Date();
    return date.getTime().toString();
  }
}

Method 2

Pass in the payment parameters as an object to the component data attribute.

import { Component, OnInit } from "@angular/core";
import {
  FlutterwaveService,
  InlinePaymentOptions,
  PaymentSuccessResponse,
} from "flutterwave-angular-v3";

@Component({
  selector: "app-root",
  template: ` <flutterwave-make-payment
    [data]="paymentData"
  ></flutterwave-make-payment>`,
})
export class AppComponent {
  publicKey = "FLWPUBK_TEST-0b0-XXXXXXXXXXX";

  customerDetails = {
    name: "Demo Customer  Name",
    email: "[email protected]",
    phone_number: "08100000000",
  };

  customizations = {
    title: "Customization Title",
    description: "Customization Description",
    logo: "https://flutterwave.com/images/logo-colored.svg",
  };

  meta = { counsumer_id: "7898", consumer_mac: "kjs9s8ss7dd" };

  paymentData: InlinePaymentOptions = {
    public_key: this.publicKey,
    tx_ref: this.generateReference(),
    amount: 10,
    currency: "NGN",
    payment_options: "card,ussd",
    redirect_url: "",
    meta: this.meta,
    customer: this.customerDetails,
    customizations: this.customizations,
    callback: this.makePaymentCallback,
    onclose: this.closedPaymentModal,
    callbackContext: this,
  };

  constructor(private flutterwaveService: FlutterwaveService) {}
  makePaymentCallback(response: PaymentSuccessResponse): void {
    console.log("Pay", response);
    this.flutterwaveService.closePaymentModal(5);
  }
  closedPaymentModal(): void {
    console.log("payment is closed");
  }
  generateReference(): string {
    let date = new Date();
    return date.getTime().toString();
  }
}

Using Flutterwave directly in your code

Method 1

Using the Flutterwave service.

import { Component } from "@angular/core";
import {
  FlutterwaveService,
  InlinePaymentOptions,
  PaymentSuccessResponse,
} from "flutterwave-angular-v3";

@Component({
  selector: "app-root",
  template: `<button (click)="makePayment()">Pay</button>`,
})
export class AppComponent {
  publicKey = "FLWPUBK_TEST-XXXXXXXXX";

  customerDetails = {
    name: "Demo Customer  Name",
    email: "[email protected]",
    phone_number: "08100000000",
  };

  customizations = {
    title: "Customization Title",
    description: "Customization Description",
    logo: "https://flutterwave.com/images/logo-colored.svg",
  };

  meta = { counsumer_id: "7898", consumer_mac: "kjs9s8ss7dd" };

  paymentData: InlinePaymentOptions = {
    public_key: this.publicKey,
    tx_ref: this.generateReference(),
    amount: 10,
    currency: "NGN",
    payment_options: "card,ussd",
    redirect_url: "",
    meta: this.meta,
    customer: this.customerDetails,
    customizations: this.customizations,
    callback: this.makePaymentCallback,
    onclose: this.closedPaymentModal,
    callbackContext: this,
  };
  //Inject the flutterwave service
  constructor(private flutterwaveService: FlutterwaveService) {}
  makePayment() {
    this.flutterwaveService.inlinePay(this.paymentData);
  }
  makePaymentCallback(response: PaymentSuccessResponse): void {
    console.log("Payment callback", response);
  }
  closedPaymentModal(): void {
    console.log("payment is closed");
  }
}

Method 2 (Promise)

Async Payment Response.

import { Component } from "@angular/core";
import { FlutterwaveService, AsyncPaymentOptions } from "flutterwave-angular-v3";

@Component({
  selector: "app-root",
  template: ` <button (click)="payViaPromise()">Pay via Promise</button>`,
})
export class AppComponent {
  publicKey = "FLWPUBK_TEST-XXXXXXXXX";

  customerDetails = {
    name: "Demo Customer  Name",
    email: "[email protected]",
    phone_number: "08100000000",
  };

  customizations = {
    title: "Customization Title",
    description: "Customization Description",
    logo: "https://flutterwave.com/images/logo-colored.svg",
  };

  meta = { counsumer_id: "7898", consumer_mac: "kjs9s8ss7dd" };

  paymentData: AsyncPaymentOptions = {
    public_key: this.publicKey,
    tx_ref: this.generateReference(),
    amount: 10,
    currency: "NGN",
    payment_options: "card,ussd",
    meta: this.meta,
    customer: this.customerDetails,
    customizations: this.customizations,
  };

  constructor(private flutterwaveService: FlutterwaveService) {}

  payViaPromise() {
    this.flutterwaveService.asyncInlinePay(this.paymentData).then((response) => {
      console.log("Promise Res", response);
      this.flutterwaveService.closePaymentModal(5);
    });
  }
  generateReference(): string {
    let date = new Date();
    return date.getTime().toString();
  }
}

Recurring Payments

Pass the payment plan ID into your payload to make recurring payments.
