How to Choose an Online Payment Solution

How to choose Online Payment Method is our choice

The payment provider is selected based on a number of criteria. Among these are the availability of services in the country where your bank account is located, transaction costs, monthly fees, integration costs, and whether it solves tax issues or allows integration with other popular payment methods. Most of these questions should be answered by you the customer. Stripe was our preferred choice because it had the best API capabilities. This article will use Stripe as its payment processor.

Best practices for payroll providers

Try again if the operation is not successful

The transaction may fail not due to technical reasons but sometimes insufficient funds may be the reason. You should try to process the transaction again between an hour and a few days later.

Find out when your CC will expire

Some of the cards become invalid or their data is no longer valid for various reasons. When you don’t have valid CC data billing the customer is not possible. Major credit cards provide you with a service that allows you to check if there are any pending changes to the customers you keep. Some online payment methods also change your credit card information. Stripe has done this for most MasterCard, Discover, and Visa cards. Not just CC.

Be aware that in some areas people do not want to pay by credit card

The best example of this is China where Alipay is the main source of payments. It’s important to note that not all customers are happy to provide their card details so using a popular payment method helps increase the number of transactions. Stripe also supports China’s Alipay and Europe’s Giropay, iDEAL

We want to have PayPal

Sometimes customers just want to use PayPal as they are used to the brand. Don’t be stubborn – Stripe will help you maximize your profits. Stripe and Paypal are direct competitors and there is no integration between them.

Best practices when using the Stripe payment method

PCI compliant Stripe

Most users comply with PCI by completing the Self-Assessment Questions (SAQ) provided by the PCI Security Standards Council. The type of SAQ depends on how you collect card data. The easiest way to get PCI certified is SAQ A. The fastest way to become PCI compliant with Stripe is to make sure you qualify for the pre-filled SEQ A. If so Stripe will fill out SEQ A for you and give it to you to download. to your account tracking settings after 20 or more transactions. The way to achieve this is as follows:

– Use an Integrated form called Checkout, Stripe.js and Elements (provides better customization then Checkout). You can use react-stripe-elements which uses the Stripe.js API or the Stripe mobile SDK library. When using react-native go with tipsi-stripe. Ipsi-stripe fasteners are not supported by Stripe so the support will not officially tell you that they are SEQ-A compliant – but they are.

– If you are using the Internet, your payment pages must use HTTPS.

In both cases, the data is sent directly to Stripe without going through your servers. If you choose the fast option you won’t have to do anything else. It’s as simple as this until you reach 6 million transactions per year then you will need to complete a Compliance Report to ensure your PCI compliance each year.

Prepare for technical failure – The Secret of Idempotency

If you are using an API to make payments you should be prepared for technical failures as all networks are unreliable. If a failure occurs it is not always possible to know whether a crime has been committed or not. If the network is down you should try again. The key to Idempotency is how to avoid double customer returns. If for some reason you made the payment twice – what can happen due to retrying the job after a failure. In the Stripes node lib you only add to the options you are paying for. Each Idempotency key will expire after 24 hours so after that if you make a payment with the same Idempotency key you will pay the customer.

Billing lines in cents not dollars

Online payment methods such as PayPal pay in dollars and not cents. But at Stripes all payments are made in very small amounts. This isn’t just about dollars, Stripes does all the money.

Try it

Stripe offers multiple card numbers to test different transactions up front and tokens to test directly on your back end. For example you cannot test Visa, Mastercard, American Express, Discover, Diners Club and JCB Cards as well as international cards and 3D Secure Cards. Stripe also gives you tokens to test for failed transactions such as a payment being declined, or a payment being denied due to fraud, an expired card, or a processing error. So you will be prepared for anything that may happen during your stay.

Don’t put JSON in the description – Use metadata

Be as descriptive as possible. Metadata is your friend. You can augment your Stripe sales with regular data so you can see it on the dashboard. For example you can add things like customer_id or shipping_id in the metadata so there is no need to pollute your description.

Should I collect more information?

The least you can get from CC is its number, CVV and expiry date but you can collect more. You can also collect zip code / CC name / Address Verification System (AVS) address. If you collect them it will increase the security of the payment because the fraud prevention algorithms will have more data and will be able to act correctly. However, from the user’s point of view it is a lot of data – which is not always good. Customers are only human and sometimes make mistakes when entering data which can also lead to rejection. So you have to decide how much data you want and what will work for you and your budget. Banks in the same way sometimes refuse payments that are responsible for ‘dishonor’ and you should contact your customer so that they can ask their bank for the reason (the number of recent transactions on the card, the lack of AVS information, the card. exceeds its limit, or other reasons that only the bank would know).

An Example of a Linear Payment

CC data collection – (explanation of indicators and example)

To collect CC data we can use Checkout, Stripe.js lib elements, react Stripe elements lib which uses Stripe js, mobile libs, and react tipisi-stripe. Checkout offers several forms of data collection, while some methods require you to create your own form. The process of securely collecting CC data using a payment provider is called tokenization as we exchange all private data to get a short version of the data. And that’s all the sign is about. This token can be used later for one-time customer billing or customer creation (See section below). The following example will focus on a simple way to display a token called Checkout. When using Checkout we have two options, simple and custom. Let’s see in the code.

Easy checkout process

By exiting the easy way everything is presented to you from several options. All you have to do is put this code on your website:

Now let’s see what we can do with the token on the backend

Customer billing – example

The sign goes backwards. Let’s use node to create a customer and bill him based on the returned customer id when needed.

import stripeModule from ‘stripe’;

import config from ‘../config/config’;

import logs from ‘../log’;

class StripeService {

constructor ()

const line = config();

this.stripe = stripeModule(stripe.secretKey);

createCustomer(stripeToken, email) {

logger.info(`creating client $email`);

return this.stripe.customers.create(

email,

source: stripeToken,

);

This will return the signal but remember to handle the errors that arise. If the answer is successful just check the client id and save it for future use. You will use the customer id to bill the user. Let’s see how to do this:

chargeCustomer(customerId, amount, desc, idempotencyKey)

return this.stripe.charges.create(

increase,

currency: ‘usd’,

customer: customerId,

Description: desc,

,

idempotency_key: idempotencyKey,

);

Is that all? Yes, but please remember to plan for failure and try again when necessary.

Registering for events – example

Stripe can change a customer’s CC after it expires and this works for most MasterCard, Discover, and Visa cards. How is it possible?- Stripe works with credit card networks and automatically tries to update card information every time a customer receives a new card. When the card information is updated you will receive a webhook with an event like this: “customer.source.updated.” You can also register to be notified before the expiration date with the event “customer.source.expiring.” Webhook is a common way to register various events that will be generated by Stripe. You will be invited by them in a push-pull manner to learn more and all you have to do is reveal the webhook. If you only want to pay by credit card using Stripe webhooks is not necessary. Webhooks are configured in the webhooks settings section of the Dashboard, where you can add a new URL to receive webhooks. The webhook values ​​must be null and the webhook signature must be verified.

import stripeModule from ‘stripe’;

enter text from ‘express’;

import bodyParser from ‘body-parser’;

const STRIPE_SECRET_KEY = ‘sk_test_your_key_here’;

const WEBHOK_SECRET = ‘whsec_your_key_here’

const stripe = stripeModule(STRIPE_SECRET_KEY);

const app = express();

app.use(require(“body-parser”).raw(type: “*/*”));

// this will be called by strokes

app.post(‘/webhook/test’, (req, res) =>

const signature = req.headers[‘stripe-signature’];

const event = stripe.webhooks.constructEvent(req.body, signature, WEBHOK_SECRET);

// Update the event – make sure it’s not active

if (eventWasNotProcessed(event))

handleEvent(event);

res.json(received: true);

);

app.listen(8000, () => console.log(“Running on port 8000”);

Other features of Stripe

Stripe’s services are not just an extension of the Payments services we have seen in this article. Stripe also offers:

– Subscription: Billing customers for recurring subscriptions. Stripe has several plans for each customer including discounts

– Connect: The solution to use when you act as a platform between customers and suppliers. With this solution you can transfer money from/to your customers and suppliers.

– Sigma: A tool for writing reports that will be available on your dashboard. This is done by writing ANSI SQL queries against the Stripe schema. You can also use programmed questions to automatically add content – results will be sent as events on the website or via email. Just be aware that using sigma is not free and will incur additional costs.

– Radar – Machine learning for anti-fraud. You can use it when integrating with Checkout, Stripe.js, Elements, and mobile SDK integration (tips-stripe will work here too).

Brief explanation

With this information you can prepare your first payment. When choosing Stripe remember that you are responsible for your PCI compliance after the first 6 million transactions.
