Minimal Stripe Wrapper

Minimal Stripe Wrapper (MSW) is a lightweight and secure WordPress plugin designed to streamline Stripe payments with minimal setup and maximum flexibility.

External services

This plugin connects to the Stripe API in order to initiate a Stripe Checkout session and to receive a Webhook response.

You may specify what information is supplied to Stripe.

The minimum information you must supply is the payment amount.

You may optionally include a Users email, product name and quantity.

Where an email is not supplied, Stripe will require the user to enter an email.

How it Works

You can initiate a Stripe payment with any of these methods:

• The Gutenberg block element ‘Minimal Stripe Button’

• By using any clickable element of your choice (eg. a <button> or <a>)

• By using the shortcode-generated button.

• By using an action hook.

• By using the shortcode-generated donate-form.

Method 1: A Gutenberg block element

Add to your page using the WordPress block editor.

Method 2: Use an existing clickable element

Add a css class to any clickable target element.

eg. Use the page builder of your choice (eg. A Divi Button).

class="mswr-stripe-payment"

Then add a filter hook to enter/modify your specific payment details.

For example:

add_filter( 'mswr_pre_stripe_checkout', function( $args ) {

// add payment details $args[ 'amount' ] = $amount; // use the smallest unit of your currency. ie. com; // eg.

wp_get_current_user()->user_email; $args[ 'product' ] = 'Your Product/Service name'; // will appear on the Stripe Checkput page $args[ 'user_meta' ] = 'Membership Renewal'; // user-defined tag that can help identify a transaction in the Stripe webhook callback

return $args; });

Method 3: Using a shortcode-generated button

This method requires no php code. You can however, optionally add a php hook (as above) to modify the Stripe parameters and to perform extra actions on the Stripe webhook callback.

Example shortcode:

com" product="Sample Product" quantity="2" success_url="/payment_success" cancelled_url="/payment_cancelled"]

Method 4: WP hook

A developer method.

Use PHP from your code to fire a WordPress ‘action’ which initiates a Stripe Checkout session with the specified Stripe arguments

Action hook: mswr_initiate_stripe_payment

Example:

$args = [ 'amount' => '12345' ]; add_action( 'mswr_initiate_stripe_payment', $args );
