I'm glad to see so much interest in this payment plugin. I originally looked at creating a payment plugin for woocommerce about a year ago but I opted to created one for OpenCart e-store instead. I hope to see stellar plugins on all the e-stores at some point. I also feel woocommerce is an important one to have as wordpress is so popular.
Just to show there are other options for stellar payments and e-store I show you what we have on the OpenCart e-store plugin.
The OpenCart Stellar payment Plugin supports any stellar asset as payment. It also supports an optional 3rd party escrow system. It uses the not yet standardized but supported QR-code protocol system for payment checkout. At this point the only wallets that fully supports automated payments for it are Stargazer and my_wallet. Oh you can pay with other wallets but they requires manually entering payment info and memo details.
To check out the code and trying it out on the demo test store site:
https://github.com/sacarlson/OpenCart_stellar_plugin : Stellar.org Net payment plugin addon for OpenCart online store management system with built in 3rd party escrow option. You can check out the new plugin on the now active test store using testnet fake money at: https://www.funtracker.site/test_store/ . To access fake money you can use funds from this wallet link: https://sacarlson.github.io/my_wallet/?json=%7B%22seed%22:%22SAYRX7D4XXTMBKNGDG7TV2WLVJ2UEJPNGS3JQTDADX4J4X66XAMVDGHT%22%7D. Now also works with our new branched version of Stargazer android wallet with added V3.0 QR-code support (see bellow).
