Install

Usage

Create a component under src/components called PaymentForm.js and add the code below to it

This code includes the creation of a service called the StackPayService.js, created under src/services. The sample code for that is below.

import React, { Component } from 'react';
import ReactDom, { render } from 'react-dom';
import Card from 'stack-pay-hosted-payments-react';

// import SupportedCards from './Cards';
import {
  formatCreditCardNumber,
  formatCVC,
  formatExpirationDate,
  formatFormData
} from '../../utils';

import './styles.css';
import api from '../../services/StackPayService';

export default class PaymentForm extends Component {
  constructor(props) {
    super(props);

    this.state = {
      number: '',
      name: '',
      expiry: '',
      cvc: '',
      issuer: '',
      focused: '',
      formData: null,
      paymentToken: '',
      error: null,
      processing: true,
      complete: false
    };
  }

  handleCallback = ({ issuer }, isValid) => {
    if (isValid) {
      this.setState({ issuer });
    }
  };

  handleInputFocus = ({ target }) => {
    this.setState({
      focused: target.name
    });
  };

  handleInputChange = ({ target }) => {
    if (target.name === 'number') {
      target.value = formatCreditCardNumber(target.value);
    } else if (target.name === 'expiry') {
      target.value = formatExpirationDate(target.value);
    } else if (target.name === 'cvc') {
      target.value = formatCVC(target.value);
    }

    this.setState({ [target.name]: target.value });
  };

  handleSubmit = e => {
    e.preventDefault();
    const { issuer } = this.state;
    const formData = [...e.target.elements]
      .filter(d => d.name)
      .reduce((acc, d) => {
        acc[d.name] = d.value;
        return acc;
      }, {});

    this.setState({ formData, issuer });

    api
      .returnPaymentMethodToken(this.state)
      .then(payload => {
        console.log('Payment Method Payload: ', payload);
        this.setState({
          paymentToken: payload.token,
          error: null,
          processing: false,
          complete: true
        });
      })
      .catch(error => {
        console.log('Payment Method Error: ', error);
        this.setState({
          stackPayError: `Failed to create paymentMethod Token: ${error.message}`,
          processing: false
        });
      });

    this.form.reset();
  };

  render() {
    const { name, number, expiry, cvc, focused, issuer, formData } = this.state;
    return (

Don't forget to import the stack-pay-hosted-payments-react/lib/styles.scss if you are using SASS in your project.
Or you can import the CSS:
import 'stack-pay-hosted-payments-react/es/styles-compiled.css';

Communicating with Stack Pay API ( StackPayService.js)

Create a service in your src/services directory

import axios from 'axios';
const returnPaymentMethodToken = (options: {}): Promise<string> => {  
  return axios({
    method: 'post',
    url: `http://localhost:9080/api/token`,
    data: {
      Order: {
        Account: {
          Type: options.issuer,
          Number: options.number.replace(/\s+/g, ''),
          ExpireDate: options.expiry.replace(/\//g, '')
        },
        AccountHolder: {
          Name: options.name,
          BillingAddress: {
            Address1: '1234 Payment Method Dr',
            City: 'Frisco',
            State: 'TX',
            Zip: '75034'
          }
        }
      }
    },
    headers: {
      Accept: 'application/json',
      'Content-Type': 'application/json',
      Authorization: 'Bearer sp-api-12345'
    }
  })
    .then(result => ({ token: result.data.Body.Token }))
    .catch(error => ({ error: error.error_message }));
};

const api = {
  returnPaymentMethodToken
};

export default api;
