# Concepts ## Messaging Window & Response Time Similar to WhatsApp, Meta enforces a **24-hour messaging window** for businesses to respond to customer-initiated messages. After 24 hours, the window closes and you can no longer initiate messages to the customer. *** ## Automation & Quick Replies Businesses can set up **automated responses** for frequently asked questions and use **quick replies** to improve response efficiency. *** ## Message Types & Media Support Instagram and Facebook support various message formats, including: * Text messages * Images & videos * Carousel posts * Quick reply buttons * Story mentions & responses *** ## Instagram Story Interactions Customers can initiate conversations by responding to Instagram Stories, providing a great way for businesses to engage with their audience. *** ## Pricing & Limits Unlike WhatsApp, Instagram, and Messenger do not have conversation-based pricing, but businesses should adhere to **Meta’s fair usage policies** to avoid limitations on messaging. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
