The payment provider is chosen based on many different criteria. Some of these are the service availability in the country where your bank account is, costs of a transaction, monthly fees, the costs of integration, and whether it resolves sales tax issues or allows for integration with some other well-known payment solutions 網上交友平台. Many of these questions must be answered by You the client 交友網. Stripe is our preferred choice as it had excellent API capabilities. This article will use Stripe as its payment processor of choice.
Best Practices for payment providers
Retry if transaction did not succeeded
The transaction might fail not only due to technical reasons but sometimes insufficient funds might be the reason. You should retry processing the transaction between an hour to couple of days later.
Know when your CC will expire
Some of the card details will expire or their data will no longer be valid for various reasons. When you do not have valid CC data charging the customer will not be possible 識女仔方法. The major card schemes offer a service that lets you check if there are any updates pending for the customer data that you store. Some of the online payment solutions will even update card information for you. Stripe will do this for the majority of MasterCard, Discover, and Visa cards. Not only CC.
Be aware that in some parts of the world people are not willing to pay with their Credit Card
The best example of this is China when Alipay is the main payment source. It is worth noting that not all clients are happy giving away their card details so using a well-known payment method helps to increase the completion rate of potential transactions. Stripe also supports Alipay for China and for Europe Giropay, iDEAL
We would like to have PayPal
Sometimes clients just want to use PayPal as they are familiar with the brand. Don’t be stubborn – Stripe will help to maximize your profit. Stripe and Paypal are direct competitors there is no integration between them.
Best practices while using the Stripe payment process
PCI compliance with Stripe
Most users become PCI compliant by filling in the Self-Assessment Questionnaire (SAQ) provided by the PCI Security Standards Council. The type of SAQ depends on how you collect card data. The simplest method of PCI validation is SAQ A. The fastest way to become PCI compliant with Stripe is to make sure you qualify for a prefilled SEQ A. If so Stripe will fill the SEQ A for you and will make it available for you to download to your account’s compliance settings after the first 20 or so transactions. The way to achieve this is as follows:
– Use the Embedded form called Checkout, Stripe.js and Elements (it offers better layout customization then Checkout). You can use react-stripe-elements which uses Stripe.js API or Stripe mobile SDK libraries. When you’re using react-native go with tipsi-stripe. ipsi-stripe bindings are not officially supported by Stripe so support will not officially tell you that they qualify for prefilled SEQ-A compliance – but they do.
– If you are using web serve your payments pages should use HTTPS.
In all those cases data is securely transmitted directly to Stripe without it passing through your servers. When you choose the fastest way you will not have to do anything more. It is as simple as this until you reach 6 million transactions per year then you will have to fill a Report on Compliance to validate your PCI compliance annually.
Prepare for technical failure – Idempotency key
If you are using API to take payments you must prepare for a technical failure as all networks are unreliable. If failure happens wit is not always possible to know if a charge was made or not. In the case of a network failure you should retry the transaction. The Idempotency key is a prevention mechanism against charging a customer twice. If for some reason you submitted the payment twice – which may occur due to retrying operations after a failure. In Stripes node lib you just add it to options parameter while charging. Each Idempotency key will time out after 24 hours so after that time if you make a payment with the same Idempotency key you will charge the client.
