Customers ask for prices then order in free-form chat — staff retype it, quantities go wrong, totals are forgotten, proof photos cannot be matched to an order.

This is WACO's "shop inside the chat" — no Meta Commerce Manager, no catalog approval. You write the products and prices in the portal; the rest is a deterministic chat flow.

The customer's flow

1. Types a keyword (katalog, produk, pesan, or your own), picks "Send product catalog" in the interactive menu, or staff type /katalog in a private note.
2. Receives the product list: a WhatsApp list message (up to 10 products, name + price), or option buttons in live chat.
3. Picks a product → asked for a quantity (a number). The product image is sent if you filled in its URL.
4. The cart is shown with Add more, Finish & pay, Cancel.
5. Finish → a numbered order (e.g. P-000123) with summary, total, and your bank accounts, plus the instruction: "type sudah bayar and enter the order number as the invoice".
6. The customer confirms through Payment confirmation; an order number entered as the invoice links the two automatically. A payment marked valid (API) sets the order to paid and notifies the customer.

The team's flow

• Every order becomes a private note in the customer's conversation, labelled pesanan (created automatically) — the team replies from the inbox as usual.
• Catalog → All orders: filter by status (awaiting payment, paid, processing, completed, cancelled), change status with one button (the customer is notified), download CSV.
• For your system: webhooks pesanan.baru and pesanan.status, plus GET /api/v1/pesanan, POST /api/v1/pesanan/{id}/status, and POST /api/v1/katalog/kirim. Details in the API documentation.

Setting it up

1. Open Catalog, fill in name, price, short description, and optionally an https image URL per product. Up to 10 products — the WhatsApp list limit.
2. Write your bank accounts one per line, review the opening message and the order summary (variables {nama} {nomor} {ringkasan} {total} {rekening}).
3. Tick Turn the catalog on, save, then try it from the Send a test card.
4. Make sure Payment confirmation is on as well so payments are captured.
