Create a Custom Cashtab Button / Integration

import React from 'react'
import { CashtabBase, formatAmount } from 'cashtab-components'

import styled from 'styled-components'

const CoolButton = styled.button`
  background-color: rebeccapurple;
  color: lime;
  border-radius: 24px;
`

const MyButton extends React.Component {
  render() {
    // Props from higher order component
    const {
      handleClick,
      to,
      step,

      price,
      currency,

      coinType,
      coinDecimals,
      coinSymbol,
      amount,

      showQR,

      isRepeatable,
      repeatTimeout,
      watchAddress,
      } = this.props;

    return (
      <div>
        <h3>Donate {price}{currency} to {to}</h3>
        <h4>Satoshis: {formatAmount(amount, coinDecimals)}</h4>
        <CoolButton onClick={handleClick}>Custom looking button with render</CoolButton>
      </div>
    )
  }
}

// Wrap with CashtabBase higher order component
export default CashtabBase(MyButton);

Control Step from app

When accepting payments, the state of the payment should be handled by the backend of your application. As such, you can pass in stepControlled with the values of fresh, pending or complete to indicate which part of the payment the user is on.
