6.4 Payment Gateways

In this section, we will review the advantages and drawbacks of various payment gateways. Payment gateways are companies that charge a fee to process orders. The free ranges from 1 percent to 5 percent. There may also be set up fees and monthly charges.

Why Use Stripe Instead of PayPal

03

Pay Pal Hidden Funds and Frozen Funds Problems

In 2012, there were many cases of customers ordering products online and paying for them with Pay Pal, but Pay Pal had a miscommunication with retailers who never received online confirmation that the payments were made. Instead, Pay Pal would return a “still pending” code to the retailer. The customer had proof of payment and the retailer even received the payment. But there was a breakdown in communication.

I personally do not recommend Pay Pal for an equally important reason. PayPal has frequently frozen funds of retailers for months on end with no way for retailers to get access to those funds. PayPal has been known to suspend retailer accounts and hold retailer funds for 6 months or more. Here is a graphic you get when your account is suspended:

PayPal is therefore a bad option for both customers and retailers. By contrast, I am not aware of Stripe ever failing to notify retailers that a payment was made or failing to pay retailers in a timely fashion. Save yourself and your customers a bunch of headaches. Use Stripe instead of PayPal.

How to set up and use Stripe

Stripe Tips

Click Managing your Stripe Account.

 Test and live modes

Every account is divided into two universes: one for testing, and one for running on your live website. All API requests exist in one of those two universes, and objects in one universe cannot be manipulated by objects in the other.

In test mode, credit card transactions are not processed through the actual card networks and only our test card numbers can be used

 API keys

Related to these universes are your API keys. Each key exists either in the live universe or in the test universe, and this is how Stripe tells what universe you are interacting with. You should only use your test API keys for testing. This will make sure that you don't accidentally modify your live customers or charges.

In addition to live and test mode, there are also two types of API keys: publishable and secret.

 Activating your account

Before activating your account, you can only interact with Stripe in test mode. All of Stripe's features are available in test mode, though no live charges using the card networks can be created.

Activating your account is a simple process: you fill out a form requesting some basic information about your product, your business, and your own personal relationship to your business. Once you've activated your account, you can immediately start using the live API and charge real cards.

Your account details are reviewed internally to ensure they comply with our terms of service. If we see a problem, we'll get in touch right away to resolve it as quickly as possible.

Next click on Your Account, then Activate Account in the top menu to fill out the application to activate your account.

07

Put in what you are selling like memberships, course fees or campaign donations.

If you have a business EIN number associated with your business bank account, you can enter this. It only takes five minutes to get a business EIN number from the IRS and most banks require this any way to set up your business account.

Then enter the address of your business, which may be your home address. Finally, enter the domain name for your website which should be online and at least partially operational.

Log in with your Google business related Gmail address to verify your identity.

Payment Template Customization

You can change colors and design of the plugin using template overrides in Joomla.

The path to the files: /plugins/pcp/stripe/tmpl/ Here are the folloing files: elements_style.php and stripe.php which can be customized via the template override.

You can create an override in templates/your_template/html/plg_pcp_stripe/elements.php and change the style in it. It uses stripe.com/payments/elements so you can choose from existing examples.

If you open elements.php file, you will see which CSS classes are defined and can be used.
Custom templating is what the client should do personally.

How to change "Pay with Stripe" text:
Go to Languages > Language override and make an override :

Language constant:
PLG_PCP_STRIPE_BUTTON_TEXT
Text:
Pay with Stripe (write your own text here)

Add custom CSS to your Joomla template:

.stripe-payment-form .card-container {background-color:#222}

.stripe-payment-form fieldset {background:#555}

.stripe-payment-form fieldset legend {color:#fff}

Open elements_style.php and change color: "#32325D", to color: "#999", You will get the following result:

24

Note: Make sure your Stripe API version is identical to API used in the payment plugin! If you see there is a new Stripe API version available in the dashboard and your plugin uses the previous version - do not upgrade Stripe API. Instead, await the new version of the plugin which will include an update of Stripe API.
