# Live commerce glossary > The most common terms in selling on Instagram lives, with short definitions and what each one means in GoLiveCommerce. Original page: https://golivecommerce.com.br/en/glossary Updated: 2026-10-16 Summary: Short definitions of live commerce terms such as stock reservation, waitlist, checkout DM, PIX, abandoned cart, average order value and Brazil's LGPD. ## Terms **Live commerce.** Selling products during a live broadcast. The seller shows items on camera, the audience asks questions and buys in real time, and the order is closed through a comment, a message or a link. In Brazil, the format is widely used on Instagram. Read the [Instagram live commerce guide](https://golivecommerce.com.br/en/instagram-live-commerce). **Trigger comment.** A comment the audience writes during the live to order a product, such as “quero 01” (“I want 01”) or “2x camiseta preta” (“2x black tee”). Shoppers comment in Portuguese, and GoLiveCommerce recognizes this pattern and creates the order. See [how it works](https://golivecommerce.com.br/en/how-it-works). **Product code.** A short identifier, such as 01 or CAM-PRETA, that the store assigns to each item and that the shopper types in the comment. The shorter and clearer the code, the fewer reading mistakes. **Product nickname (alias).** An alternative name that also identifies the product in a comment. For example, “camiseta preta” (“black tee”) and “blusa preta” (“black top”) can both point to the same item. Nicknames help recognize orders written in free form. **Stock reservation.** Setting aside a quantity of a product for an order so the same item isn't sold twice. The reservation lasts for a set time. If payment doesn't happen, it expires and the item goes back to available stock. **Waitlist.** A list of shoppers who ordered a product after it sold out. If a reservation is released, the next person in line can be notified. It keeps you from losing the interest of people who arrived late. **Checkout DM.** A direct message (DM) sent to the shopper on Instagram with the order summary and the payment link. It moves the shopper from a public comment to a private, organized place to buy. **Checkout.** The final step of a purchase, where the shopper reviews the items, enters shipping details and chooses how to pay. In GoLiveCommerce, checkout is a page opened from the link in the DM. **PIX.** The instant payment system run by Brazil's Central Bank, available 24 hours a day. The shopper pays with a QR code or a copy-and-paste code, and the payment is confirmed in seconds. See [selling on a live with PIX](https://golivecommerce.com.br/en/sell-on-instagram-live-with-pix). **PIX copy and paste.** A text string that represents a PIX charge and can be pasted into the banking app, with no QR code to scan. Useful when the shopper is paying on the same phone they used to open the link. **Abandoned cart.** An order that was started but not paid. In live commerce, it happens when a shopper comments, gets the link and doesn't finish paying. See how to [reduce abandoned carts in lives](https://golivecommerce.com.br/en/blog/reduce-abandoned-carts-in-lives). **Conversion rate.** The share of people who completed an action out of everyone who could have. In lives, a useful measure is paid orders divided by orders started. **Average order value.** The average amount per paid order, calculated by dividing revenue by the number of orders. It helps you evaluate bundles, free shipping above a certain amount and which products to show. **Discount coupon.** A code that takes money off an order, as a percentage or a fixed amount. You can use it to encourage payment within a deadline during or right after the live. **Webhook.** An automatic notice one system sends to another when something happens. Instagram notifies the platform of every new comment on the live, and Mercado Pago notifies it when a PIX payment is made. **OAuth (official login).** An authorization standard that lets you grant access to your account without sharing your password. The Instagram connection uses Meta's login, and you can revoke access at any time. **Instagram professional account.** A Business or Creator account. It's the type of account that can connect to outside tools through Meta's official access. Personal accounts don't have this access. **LGPD.** Brazil's General Data Protection Law (Lei Geral de Proteção de Dados, Law No. 13,709/2018), which governs how personal data is handled in Brazil. It defines roles such as controller and processor and gives rights to data subjects. See [security and privacy](https://golivecommerce.com.br/en/security-and-privacy). **Controller and processor.** The controller decides what personal data is used for. The processor handles the data on the controller's behalf. In a live sale, the store is the controller of the shopper's data and the platform acts as the processor. ## See also - [Instagram live commerce: the complete guide](https://golivecommerce.com.br/en/instagram-live-commerce) - [How GoLiveCommerce works | From comment to delivery](https://golivecommerce.com.br/en/how-it-works) - [Frequently asked questions](https://golivecommerce.com.br/en/faq) - [Live commerce blog](https://golivecommerce.com.br/en/blog) Contact: contato@golivecommerce.com.br
