I'm integrating paytm in angular 4. paytm plugin is successfully added in project , but i don't know how to import paytm plugin in ts file. and call java file file function.
please help me... here is my code
import { Nav, Platform } from 'ionic-angular';
import { Component, OnInit } from '@angular/core';
import { NavController } from 'ionic-angular';
import {} from 'jasmine';
import {LoginPage} from "../login/login";
import {SignUpPage} from "../signup/signup";
import {HomePage} from "../home/home";

@Component({

templateUrl: 'apphome.html'
})
export class AppHomePage implements OnInit {
constructor(public navCtrl: NavController ,public paytm:Paytm) {}
ngOnInit(){
window.plugins.paytm.startPayment("526", "25862", "[email protected]",
"777777777", "25", successCallback, failureCallback);
var userids=window.localStorage.getItem('userid');
//alert(userids);
if(userids!= null)
{
this.navCtrl.push(HomePage);
}
}
}
You can simply archive it.
Create CHECKSUMHASH using backend (.net, php, etc..)
with help of API and that just replace checksumhash in form. or you can create form
in component itself when you get checksumhash
from API.
Create CHECKSUMHASH with help of paytm documentation. STEP 2. and than return CHECKSUMHASH. Take all parameters from frontend.
For Example : I had used just one button for transaction not needed any form now. after checksumhash i will create form.
app.component.html :
<button type="button" (click)="submitForm()">PAY NOW</button>
app.component.ts :
constructor(private http: HttpClient) { }
// I have all below fields values
paytm = {
MID: "xxxxx", // paytm provide
WEBSITE: "WEBSTAGING", // paytm provide
INDUSTRY_TYPE_ID: "Retail", // paytm provide
CHANNEL_ID: "WEB", // paytm provide
ORDER_ID: "xxxxx", // unique id
CUST_ID: "xxxxx", // customer id
MOBILE_NO: "xxxx", // customer mobile number
EMAIL: "xxxx", // customer email
TXN_AMOUNT: "10.00", // transaction amount
CALLBACK_URL: "http://localhost:4200/paymentverity", // Call back URL that i want to redirect after payment fail or success
};
submitForm() {
// I will do API call and will get CHECKSUMHASH.
this.http.post('https://myAPI.com/createchecksum', this.paytm)
.subscribe((res: any) => {
// As per my backend i will get checksumhash under res.data
this.paytm['CHECKSUMHASH'] = res.data;
// than i will create form
this.createPaytmForm();
};
};
createPaytmForm() {
const my_form: any = document.createElement('form');
my_form.name = 'paytm_form';
my_form.method = 'post';
my_form.action = 'https://securegw-stage.paytm.in/order/process';
const myParams = Object.keys(this.paytm);
for (let i = 0; i < myParams.length; i++) {
const key = myParams[i];
let my_tb: any = document.createElement('input');
my_tb.type = 'hidden';
my_tb.name = key;
my_tb.value = this.paytm[key];
my_form.appendChild(my_tb);
};
document.body.appendChild(my_form);
my_form.submit();
// after click will fire you will redirect to paytm payment page.
// after complete or fail transaction you will redirect to your CALLBACK URL
};
