Commerce · POS integration

Bacera

An online shop and workshop booking site for a Hanoi pottery studio, built on WordPress with Pancake POS as the system of record. Its public demo replays recorded POS traffic.

• Built a WordPress plugin that integrates Pancake POS through six modules, so products, stock and orders live in the POS and the site never keeps a second inventory.
• Kept the API key on the server. Checkout calls nonce-checked REST routes that talk to the POS, and product images are proxied under the studio's own domain.
• Verified bank transfer, card and PayPal payments with payment intents that expire, plus a status endpoint that turns the POS's inconsistent "paid" signals into one answer.
• Turned the client project into a safe public demo. It replays recorded POS responses, cannot reach the real POS from its container, and resets every night on Compute Engine.
