Grails Paystack Plugin

A Grails plugin to allow communication to paystack API

Installation

Add the below line to your build.gradle file

compile 'org.grails.plugins:paystack-grails:1.0.5'

Configuration

Include Paystack keys(in application.yml) gotten from your dashboard as follows
paystack: 
    liveSecretKey: '${PAYSTACK_LIVE_SECRET_KEY}'
    testSecretKey: '${PAYSTACK_TEST_SECRET_KEY}'
    livePublicKey: '${PAYSTACK_LIVE_PUBLIC_KEY}'
    testPublicKey: '${PAYSTACK_TEST_PUBLIC_KEY}'
    endpoint:      'https://api.paystack.co'

• Note:Make sure to have your webhook registered in paystack dashboard. eg: http://paystack.dev/test/handlePaystackCallback where:
  • "test" is the controller name
  • "handlePayStackCallback" is the method name

Usage

• Make Payment Request
• params
  • email (required)
  • amount (required)
  • plan
  • first_name
  • last_name
  • metadata
  • callback_url

class TestController {

    PaystackService paystackService

    def index() { }

    def makePaymentRequest(){
        String authUrl =  paystackService.getAuthUrl(params)
        redirect(url:authUrl)
    }
  }

• Handle Paystack callback
• params(paystack calls ur method with a reference parameter)

    def handlePaystackCallback(){
       final String reference = params.get('reference') // reference from paystack webhook
        Map<String, String> paymentDetails =  paystackService.getPaymentData(reference)
         println($paymentDetails)
        // Now you have the payment details,
        // you can store the authorization_code in your db to allow for recurrent subscriptions
        // you can then redirect or do whatever you want
    }
