Paystack NODEJS

This is a library for easy integration of Paystack with your Nodejs backend. This packages eliminates a lot of issues pertanining to making calls to Paystack endpoints.

Requirements

1. Within your Config file inside your .env file create the following key:

BEARER_SECRET_KEY=sk_test_20a4725e39fsssss9727292209w8w98w8ww3ba5d58

Installation

``js
npm install paystack-solucien
`

Usage

`js
// Require the library
var paystack = require('paystack-solucien')('secret_key');
`


$3

Since you will be calling from your .env file

`js
1. require dotenv
const dotenv = require("dotenv");

2. then require package
const paystack= require("paystack-solucien")(process.env.BEARER_SECRET_KEY);
`

Making calls to endpoints

The resource methods promisified

#### The Format is: paystack.{resource}.{method}

Calling the resources with try and catch
`js
paystack.customer
.list()
.then(function(body) {
console.log(body);
})
.catch(function(error) {
console.log(error);
});
`

Calling the resources without try and catch

#### The Format is: paystack.{resource}

`js
// paystack.{resource}.{method}
paystack.customer.list(function(error, body) {
console.log(error);
console.log(body);
});
`

## Usage real world examples will require you to pass some params

#### initialize a payment

`js
exports.getPayments = asyncHandler(async (req, res, next) => {
const {
email,
amount,
plan,
reference,
start_date,
currency,
metadata,
callback_url,
cancel_url,
frequency,
duration,
name,
description,
send_invoices,
send_sms,

} = req.body;

paystack.transaction
.initialize({
//just pass the data that you need for your payment transaction
name,
email,
amount,
callback_url,
reference,
metadata,
plan,
start_date,
cancel_url,
})
.then(async (transaction) => {
console.log(transaction);
res.status(200).json({ transaction });
})
.catch((error) => {
console.log(error);
res.status(400).json({ error });
});
});
`


#### initialize a payment with subscription

#### You just got to pass the plan_code and paystack will take care of the rest

`js
exports.getPayments = asyncHandler(async (req, res, next) => {
const {
email,
amount,
plan,
reference,
start_date,
currency,
metadata,
callback_url,
cancel_url,
frequency,
duration,
name,
description,
send_invoices,
send_sms,

} = req.body;

paystack.transaction
.initialize({
//just pass the data that you need for your payment transaction
name,
email,
amount,
plan,
callback_url,
reference,
metadata,
plan,
start_date,
cancel_url,
})
.then(async (transaction) => {
console.log(transaction);
res.status(200).json({ transaction });
})
.catch((error) => {
console.log(error);
res.status(400).json({ error });
});
});
`


$3

`js
const {
email,
amount,
plan,
reference,
start_date,
currency,
metadata,
callback_url,
cancel_url,
frequency,
duration,
name,
description,
send_invoices,
send_sms,

} = req.body;

paystack.transaction
.initialize({
//just pass the data that you need for your payment transaction
name,
email,
amount,
plan,
callback_url,
reference,
metadata,
plan,
start_date,
cancel_url,
})
.then(async (transaction) => {
console.log(transaction);
res.status(200).json({ transaction });
})
.catch((error) => {
console.log(error);
res.status(400).json({ error });
});

### Example 1 (simple):

`js
const { email, id } = req.body;
//get get customer
paystack.customer
.get({
email, id
})
.then(async (transaction) => {
console.log(transaction);
res.status(200).json({ transaction });
})
.catch((error) => {
console.log(error);
res.status(400).json({ error });
});

`

### Example 2 (complex)

Let say you were using a complex controller.js file with a middleware that allowed you to run async functions on your endpoints

`js
exports.getCustomer = asyncHandler(async (req, res, next) => {
//req,body it will take the data you will send via json
const { email, id } = req.body;

//get customer
paystack.customer
.get({
//it will then pass the request data from your api to paystack api
email, id
})
.then(async (transaction) => {
//you will get access to the transaction and you will use the transactions how you see fit
console.log(transaction);
res.status(200).json({ transaction });
})
.catch((error) => {
console.log(error);
res.status(400).json({ error });
});
});
`

### Note

If you are new to Nodejs the above example is not foreign to this:

`js

//get customer
paystack.customer
.get({
//send info as hardcorded json data
email: "useremail@email.com",
id: 933383930
})
.then(async (transaction) => {
console.log(transaction);
res.status(200).json({ transaction });
})
.catch((error) => {
console.log(error);
res.status(400).json({ error });
});

#### Generate a link for the user so they update their card

#### Example 1:

`js
exports.updatePayment = asyncHandler(async (req, res, next) => {
const { subscription_code } = req.body;


//get subscription
paystack.subscription
.update({
subscription_code
})
.then(async (transaction) => {
console.log(transaction);
res.status(200).json({ transaction });
})
.catch((error) => {
console.log(error);
res.status(400).json({ error });
});
});
`

#### Example 2 without the complexity

`js
const { subscription_code } = req.body;
//get subscription
paystack.subscription
.update({
subscription_code
})
.then(async (transaction) => {
console.log(transaction);
res.status(200).json({ transaction });
})
.catch((error) => {
console.log(error);
res.status(400).json({ error });
});
