Gravity Forms + Stripe

http://wordpress.org/plugins/gravity-forms-stripe/

Stripe allows you to process credit cards directly on your site, securely and easily, without having to deal with merchant accounts, PCI-compliance, or PayPal.

This Gravity Forms add-on integrates Stripe with your forms using Stripe.js to make sure sensitive card information never hits your server.

• Also, neither Gravity Forms nor Stripe provides support for this plugin.
• If you think you've found a bug, or you're not sure if you need to purchase support, feel free to contact me.

Current Limitations

• Cannot have Stripe Add-On "activated" at the same time as Authorize.Net or PayPal Pro Add-Ons
• For security reasons, credit card field has to be on the last page of a multi-page form
• One Stripe form per page

Reported Conflicts

• plugin: Shortcodes Ultimate
• plugin: PHP Shortcode Version 1.3
• theme: Themeforest themes that strip shortcodes
• plugin: Root Relative URLs

Installation

1. Make sure that Gravity Forms is activated
2. Upload gravityforms-stripe to the /wp-content/plugins/ directory
3. Activate the plugin through the 'Plugins' menu in WordPress
4. Add your Stripe API keys to the Stripe tab on the Settings page (Forms->Settings).
5. Create a form, adding at least one product field along with the new 'Credit Card' field that appears under 'Pricing Fields.' Keep in mind that Stripe accepts a minimum charge of $0.50 - this means that the total amount of your form must be at least $0.50.
6. Under Forms->Stripe, add a Stripe feed for your new form.
