I have a JS front-end that communicates with the back-end via REST API and I need to process credit cards. I do not want to get into the full PCI DSS compliance stuff and I don't need to since I am using 3rd party provider(Stripe, Braintree..) that provide tokenization.
But the issue I have is that I do not want the JS front-end to handle the tokenization of the CC details but I want the front-end to send the CC data to the back-end and the back-end will then use the payment gateway API to tokenize the CC data and store it instead of the real CC data.
Since the CC data enters the back-end is is considered processing of the CC data(not storage) which means I have to handle PCI compliance in a way.
So I am wondering if there is some easy way to avoid doing some over-complicated code/infrastructure changes in order to be compliant?
If you don't want to have to qualify for SAQ C/D then you cannot send your customer's PAN to your server, period. It has to go to your payment gateway first, and then you can take whatever payload they give you and send it to your server.
Since I am more familiar with their services, I can describe the two ways Braintree handles this:
1) Drop-in UI - With this method, you'll create a div on your payment page and add a little javascript in your frontend code that converts the node into a payment form. Once they fill out the payment form, the information will sent directly to Braintree, and they will return a payment nonce to you that you can safely send to your server without any PCI concerns.
2) Hosted Fields - The options to style the Drop-in UI are a bit limited, so if you need the ability to add custom fields that you have full control to style and place on your page as you want, then you are looking for hosted fields. It basically creates a series of iframes on your page that you can style like regular HTML inputs, and then when your customer fills them out and clicks "submit," the data is once again submitted to Braintree first, and you get a payment nonce back that you can send to your backend API and do whatever you'd like.
Just to make sure I've been clear though - there is currently no way to send plaintext credit card information to your server without having to fulfill the more rigorous PCI SAQ levels.

I am currently looking into the W3C Payment Request API as part of a project for a new e-commerce checkout flow (mostly for supporting faster check-out using Apple Pay and Google Pay).
From looking at the API specification's change history, it looks like this change instituted earlier this year removes support for requesting the buyer's address with a payment request. The documentation of our payment service provider still shows this option, and it seems to work for now. That being said, I don't want to rely on a feature that browsers might start dropping soon because it's no longer in the standard, breaking our checkout flow.
Does anyone know if there is a recommended new way to handle this via the API, or if it is advisable to move the collection of the buyer's billing and shipping addresses back to a form on our page even when using the payment request API?
As far as the Payment Request API is concerned, I think there three primary options:
Apple Pay
Google Pay
basic-card
As you may have seen, basic-card is being deprecated (https://blog.chromium.org/2021/10/sunsetting-basic-card-payment-method-in.html) so you probably want to avoid this option.
Both Apple Pay and Google Pay provide access to billing and shipping address, and can be accessed as payment methods in the Payment Request API, and both provide their own alternate APIs (Apple Pay JS API and Google Pay Online API).
I don't know about Apple Pay, but the advice for Google Pay is to use Google Pay Online API (which makes use of the Payment Request API when available). Google Pay provides a consistent API for browsers that do and don't support the Payment Request API.
Does anyone know if there is a recommended new way to handle this via the API, or if it is advisable to move the collection of the buyer's billing and shipping addresses back to a form on our page even when using the payment request API?
The guidance for Google Pay is to place the Google Pay button above manual entry fields and to collect shipping information from Google Pay so that users can users don't start filling in the form before realizing there was a faster checkout option available.
So prioritize the digital checkout options for users that choose to use it, and make use of billing/shipping information from the digital wallet APIs. Make manual form fields available (suggest that form fields also make correct use of autofill attributes) for users who don't have access to or choose not to use the other payment options.
Demo site available with this in action: https://paydemo.withgoogle.com
FYI, if you're looking to integrate Google Pay into your site and are using a JavaScript framework, consider using the framework specific components from Google Pay for easier integration: https://github.com/google-pay/google-pay-button
I am working on web application where I will have to receive credit card details but only so that I can pass those details to configured payment processor and receive the card id/token which will be stored.
Usually this is done in front-end via JS request directly to the payment processor that will return nonce and then the backend does its job. But this is not my case.
Even though I will not be storing the CC data I will be technically processing them(the CC data enters the server and my code) so I need PCI certification.
But I am not a large company that can afford that so I want to avoid it, at least for now.
So I am wondering if it would be ok from security and PCI DSS point of view to create a Google Cloud function that would receive the CC data, call the application for validation and payment processor configuration, send the CC data to selected payment processor, post the token back into the application to perform what needs to be performed, and return the result from the application back to the client.
Technically, the CC data only enters the Google Cloud function instance which is certified and the CC data is only safely submitted into the payment processor which is also PCI certified. And I think in this case the Self-Assessment Questionnaire D – Service Providers should be enough without the need for certification.
Is my assumption correct?
If you are a service provider, then you need SAQ D for service providers, no matter the setup you're using. Basically if the money that is collected from the credit card goes into someone elses merchant account, then you're a service provider.
SAQ D is the hardest of the SAQs, the difference with 'certification' (there is no certification as such), or RoC, is basically that a trusted body verifies that you've done the SAQ properly. You only need the RoC, which can be in the order of $25K a year, if you process over a certain number of transactions per year.
Yes you should be able to use GCP cloud functions, and that will help with your PCI compliance, but in reality it won't make that much difference regarding the overall effort required to become PCI compliant. You still need to have all the policies and procedures in place, code reviews, SDLC, penetration testing etc etc. It's 139 pages of requirements.
The good news is you don't technically need to be PCI compliant, it's up to the merchant to use PCI compliant providers, and they do that through a contract with you stating their PCI needs. Obviously not the best approach though.
Have a talk with a QSA, it's probably worth a few hundred dollars consulting fees to see if there's anyway around it. If you're doing this as a one off for a single client, it might not be considered service provider for example.
Good luck, and it'd be great to hear what you end up doing.
I have an application that requests Credit Card information to do a payment to a third party company.
My application captures the CC, CVV, Expiration Date, etc. and then passes that information to their API that charges the customer.
I've been reading about PCI Compliance but based on the following image, I am not quite sure what level of compliance I would need to meet.
Lastly, I would like to figure out what would be the best options for me in case I have a new purchase from the same client. Since I am not charging the customer but the third party does, how would be the best way to store the payment information so user doesn't need to enter his information every single time they want to use my service? What would be the implications of storing payment information on my servers from a PCI compliance point of view? Is there a way where I don't need to store the payment information for the user but I can pass their information (if they are a returning customer) to 3rd party API and still being PCI Compliance?
Since you're building a web application (even embedded into Facebook messenger), if you're building out the form that collects card data, you're going to either fall under "Shopping Cart - Payment Page Direct Post" (which is A-EP) or "Shopping Cart - Payment Page Not Outsourced" (which is D-Merchant). You really want to be under A-EP if you can, but you may not be able to.
The difference between the two is whether or not the card data crosses through your servers. With "Direct Post", the web page itself sends the data (usually via HTTP POST) to the payment API, and you have no way to capture it. With "Not Outsourced", the data comes back to your server, which then calls the payment API and passes it along. In that case, you're going to have to go through the entire D-Merchant questionnaire (by far the longest, other than D-Service Provider), and probably have a special environment set up to prevent anything from trying to read the card data as it transits your server.
There's really no part of the card data that is worth storing to try and identify a repeat purchaser, because you won't have the payment data to actually complete a payment. Instead, you should see if your payment provider provides any type of "token", which can be used to identify that payment data later. If so, you can associate that token with the customer (however you identify a customer) and reuse it when they return.

I like to build a system that will allow users to "commit buy" a deal, but will only be charged after a minimum # of committers are reached. The time span in which the "deal" will continue can be either weekly or monthly.
I like to stay away from building one from the ground up as much as possible.
I know there's another thread on StackOverflow that asked paypal, amazon, or google checkout API to serve this purpose, but this seems too much like a hack?
I did some reading on using a gateway like Authorize.net to process credit card information and they can store the user information and has a service like pay-as-you-go. Would using their API be a better choice? Can their pay-as-you-go method provide the system that I'm looking for?

I have used Authorize.net for recurring payments and it is easy to implement if you are fluent in working with a web service (regardless of language). You can integrate with them without the user needing to leave your website and without storing the user's credit card information.
However, you will be receiving the user's credit card number to implement such a model, and there are still precautions to be taken (versus redirecting to a secure third party site to receive the number).

Been googling all day, reading numerous PDF's and still getting confused with the concepts of sending data to Payway system from Westpac (a bank in Australia). They offer access via API but also give access via what they call "NET."
The way I understand is that when client want to pay on my website, in case of NET, client gets to the page (hosted by a bank or hosted by me) where is provided with form to enter credit card info details. Then this form is submitted via normal POST call to Payway's specific https address. It is processed then and browser returns to the URL I specified as one of the parameters I sent in hidden field.
In case of API story is similar, so user receives form, fills in the data and then data is send to my backend (not Payway's). My backend then calls payway API with data provided and once answer received returns confirmation page to the client.
Is my understanding right? Please explain as I have a feeling I am missing something basic here.
There are a number of different ways to interact with PayWay Net, depending on how much control you want. The simpliest way is this:
You create a HTML format containing fields with certain names. This form is served up by your website, but when submitted goes to the PayWay website. You can add to this your own hidden fields and information fields.
Your user enters some details and clicks Submit.
Your user's browser submits the form to PayWay. PayWay validates the values and displays a page asking for credit card information (over https)
The user enters the credit card details then confirms the transaction.
PayWay processes the credit card transaction
Optionally, PayWay can conduct a post back to your server indicating the status of the transaction so you can complete the order (called server-to-server payment notification)
Optionally, PayWay can redirect the browser back to your server (but do not use this to update yoru database)
There are also ways to fully customise the credit card input page and receipt page.
PayWay API is different. You install a piece of software on your server. When you want to conduct a credit card transaction, you invoke this piece of software. It talks over the internet to the PayWay server, conducts a transaction, and gives you a response. You could use this if you were writing a phone payments system, for example, as no browser is involved in the PayWay interface.
(Disclaimer: I work for Qvalent, developers of PayWay).
Your understanding is correct.
I've done a couple of Payway integrations and have always opted for the API solution so that users get a consistent experience and are not jumping between websites.
An odd thing about PayWay, is that while most payment gateways have 2 options.. a merchant hosted or server hosted, PayWay offers this pseudo-merchant hosted with their NET option using the token request. Credit Card details are taken directly on the merchant site and only redirects the confirmation momentarily to the server and then back. This would be great if a payway account worked universally with both NET and API.. but it seems an API account doesn't support NET methods. So if you want to accept cards on your site, the NET token method is pretty much eclipsed by its bigger API brother.
