WP Stripe Plugin

Introduction

WP Stripe is a plugin designed to handle single payments using Stripe, a refreshing and accessible alternative to PayPal. This is particularly awesome for charities, non-profit organizations and other websites accepting smaller payments where transaction fees are unnecessarily high (no setup or monthly fees either).

Will it work on my Theme?

Yes! WP-Stripe features an inline form or pop-up modal so that it can fit any theme. There’s also a simple option to turn off the default CSS so that you can customize it yourself.

Features

This plugin allows you to do a number of things (see screenshots too):

• Add a Donation/Payment Form via Shortcode or Template insert
• Add a Widget showing Recent Donations/Payments (using Gravatars)
• View latest Donations/Payments in a Widget (donors can opt-in/opt-out).
• View latest Donations/Payments in a WP-Admin (makes use of custom post types to store transactions without sensitive data, see FAQ for more information).

Using SSL (Important)

In order to process transactions in a secure manner, you need to purchase an SSL Certificate. This way consumers can purchase/donate with confidence. There are multiple plugins for then enforcing that SSL be used on your page, here’s one.

Stripe Limitations

Stripe is available in a number of countries, check here to see if your country is supported.

How does WP Stripe work ?

WP Stripe uses a simple to add form to capture person & payment details. Credit card information is then passed to the Stripe servers in the form of a token, increasing security and hindering duplication.

What information does WP Stripe store?

WP Stripe DOES store basic transaction data (Transaction ID, Amounts & User Data that was voluntarily provided by the donor).

WP Stripe DOES NOT store credit card information. Upon form submission, a token is generated by stripe.js and passed through POST and then on to the stripe servers, that is the extent of it.

Does WP Stripe offer a shopping cart module?

WP Stripe is not intended to be used as an e-commerce solution, but rather to handle single payments and donations.

Does WP Stripe offer any actions or filters?

Actions

• wp_stripe_post_successful_charge (after a successful charge and saving to WP)
• wp_stripe_post_fail_charge (after a failed charge, for whatever reason)

Filter

• wp_stripe_filter_form(to filter/edit the content of the form)
