Drupal Commerce is more than just a module project. As I laid out in my session at DrupalCon Vienna, it is an entire ecosystem supported by dozens of agencies and powering well over $1.5bn in online transactions annually. This makes Drupal Commerce one of the largest open source eCommerce projects in the world, and it's thanks in no small part to our Technology Partners (comprised primarily of payment providers) that we are able to invest as much of our time in it as we do.
Braintree is one such partner and a fantastic supporter of Commerce 2.x since last Summer. During our sprint to release a beta at DrupalCon Dublin, they sponsored Bojan's time for two weeks to expand and improve the core Payment API.
As a result, they also became the first integrated payment gateway and the test case for any payment provider following their integration pattern - individual iframes embedded into the checkout form for each payment field, making it easy to securely collect payment card data through your own checkout form.
For the initial release of the Commerce Braintree integration on Drupal 8, we targeted basic credit card payment support via their Hosted Fields API. As of this week, we've finalized patches that add support for PayPal Express Checkout and PayPal Credit alongside credit card payment through Braintree. They are a PayPal company, after all!
Customers can pay via credit card on-site or Express Checkout via a modal dialog.
You can test the new features end to end by grabbing the latest release of the Commerce Braintree module and configuring it to work through the Braintree sandbox. If you get stuck, you can find us in the #commerce channel in the Drupal Slack or open an issue in the queue if that's not possible.
Thanks again to Braintree for their support and development sponsorship. If you'd like to learn more about how Technology Partners benefit our ecosystem, consider joining me and Commerce Braintree's D7 co-maintainer Andy Giles this weekend at DrupalCamp Atlanta (Nov. 3-4). I'll present a longer version of my DrupalCon session, Marketing and Selling the Drupal Commerce Ecosystem, and naturally I'll tap Andy to help me answer all your hardest questions. ; )
