PayPal has one that you can try.

Firstly, you need to have an online trading account from your bank, in this all the money that you take with card payments will be in the end. Now each bank offers different Merchant Accounts designed for different enterprises and different risk levels, and some will take x percent of your income, some will take a fixed fee, and others will take a mixture of both.

As soon as you have a Merchant Account, you need a system for paying credit cards, AKA - a payment gateway. There are many more, only Google Payment Gateway (Authorize.Net and SecPay are two examples). Again, payment gateways will receive a percentage of any money that you process through them, some paid fruits, some blame the percentage, others both. Typically, credit cards and debit cards are charged.

The payment gateway will take all your details about the Trading account and configure everything so that the money processed through them gets into your Merchant Account. However, you still need to have a form so that customers can fill out and send their card details.

Integration of a payment gateway on your website and there are 3 methods that are usually available:

  • You redirect your customers to the payment gateway, usually you need to call the web service in advance to tell the payment gateway how much you want to charge the client, what items, shipping fees, tax, etc. When a client arrives at a payment gateway, everything is covered with the logo and details of the payment gateway provider, so that the client knows that they pay through an authoritative service.
  • The same as above, but you pay an additional payment gateway provider so that you can customize the appearance of the payment forms (aka White Labeling).
  • The Payment Gateway provider provides you with the webservice API, and you provide all forms of payment by credit card, calling the API if necessary. You will also need an SSL certificate for this.

It’s great if you take a few thousand a week and want to provide your customers with a hot trip, however it can be expensive if its only a few hundred a week that you take. There are also PCI (risk and fraud) and problems with refunds.

Paypal can do this faster if you start trading online, since you do not need an online trading account with your bank. Everything else is still applicable.

There are many different ways, but here are the main two:

The real difference between the two is the amount of control needed. If you need everything that is posted on your site, and you do not want to transfer it to someone else on another site for registration, then No. 2 is your only option. Otherwise, # 1 is the easiest way ...

Content paraphrased from here , please visit the full text and a list of third-party options.

There are two ways to accept credit cards for your site:

  • Use your own trading account
  • Via a third-party seller

Some issues to consider

(trading account against a third-party merchant)

Installation fee
The initial cost of opening a trading account is usually higher than that of a third party (some of which have no fee).

Transaction fee
Much higher for using a third party compared to using your own seller account.

Convenience
Third-party merchants are convenient when you do not know if you can really make a lot of your product or service. In addition, the seller takes care of everything for you. You can focus on your products, services and customers.
Having a trading account corresponds to your business with a certain level of professionalism. However, you must be careful to minimize the risks of your credit card, as you yourself will process credit card payments. This does not mean that there are no risks associated with the use of a third-party merchant.

I just did this search and for me it came to PayPal or Authorize.NET. If you are a member of Costco, you can use Elavon , which uses Authorize.NET. Whichever way you go, take a look at the NopCommerce open source e-commerce solution that contains a lot of ASP.Net/C# code for the solution with Paypal, Authorize.NET, etc.

If you don’t know how to get started and you don’t have an existing seller account, you might consider going to someone like Paypoint.net (they are based on the UK, but I have no doubt that there is the USA and other world equivalents) that will create the whole blow for you.
