Usage

Initialise Transaction

This is done from your backend server using your SECRET-KEY as shown. ref

const https = require('https')

const params = JSON.stringify({
  "email": "[e-mail]",
  "amount": "20000"
})

const options = {
  hostname: 'api.paystack.co',
  port: 443,
  path: '/transaction/initialize',
  method: 'POST',
  headers: {
    Authorization: 'Bearer SECRET_KEY',
    'Content-Type': 'application/json'
  }
}

const req = https.request(options, res => {
  let data = ''

  res.on('data', (chunk) => {
    data += chunk
  });

  res.on('end', () => {
    console.log(JSON.parse(data))
  })
}).on('error', error => {
  console.error(error)
})

req.write(params)
req.end()

Sample Response

{
  "status": true,
  "message": "Authorization URL created",
  "data": {
    "authorization_url": "https://checkout.paystack.com/0peioxfhpn",
    "access_code": "0peioxfhpn",
    "reference": "7PVGX8MEk85tgeEpVDtD"
  }
}

An authorization_url is returned - your backend server should send this to the front end/client to checkout.

NB: Please ensure to set your redirect url when initialising the paystack transaction.

Checkout/Payment

The authorization_url sent from your backend server is used as the only parameter to Paystack Standard interface. The PaystackStandard.checkout method returns type CheckoutResponse which contains a success - bool, and the transaction reference.

PaystackStandard(context).checkout(checkoutUrl: "<authorization_url>").then((response){
// here check for success - verify transaction status with your backend server
});
