When creating a LINE customer flow, the first step is often to use a confirm template. However, as requirements evolve, the real question becomes: which LINE message type best suits the decision the user needs to make?
A confirm template is designed to present text followed by exactly two actions. It is suitable for one binary decision, such as confirming or canceling, accepting or declining, or approving or rejecting. This template has a limitation of only two actions, intended for a focused question: "Do you want to proceed?"
If the flow requires more choices, move away from the confirm template. For three or four actions, consider a buttons template, which presents a compact card with several primary actions. Quick replies are useful for temporary menus, allowing up to 13 quick reply buttons for short category lists, selecting the next workflow step, choosing a language, date, location, or answering a question immediately.
Carousel templates are ideal for browsing repeated items with multiple structured columns. Flex Messages provide custom layouts and visual hierarchy, ideal for complex interactions requiring custom branding, more complex visual hierarchy, multiple content sections, responsive layout, or structured summaries.
