WhatsApp Business API Features: What You Can (and Can't) Do in 2026

TL;DR — What the WhatsApp Business API Enables

Core Messaging Features

Text and Media Messages

The API supports every standard message type Meta exposes:

• Plain text (up to 4,096 characters)
• Images (JPEG, PNG — up to 5 MB)
• Documents (PDF, DOCX, XLSX — up to 100 MB)
• Videos (MP4, 3GPP — up to 16 MB)
• Audio (MP3, OGG, AAC)
• Stickers
• Location sharing (latitude/longitude with label)
• Contacts (vCard)

Interactive Messages

• • Reply buttons: up to 3 quick-reply options on a single message
• • List messages: menu of up to 10 sections, each with selectable rows — useful for service menus, FAQ categories, or appointment type selection
• • Call-to-action buttons: link out to a URL or trigger a phone call directly from the message

Rich Cards and Carousels

Rich cards combine a title, image, description, and up to two buttons in a single structured message. Carousels stack up to 10 cards in a swipeable sequence.

Full channel parity: rich cards and carousels render identically on WhatsApp, Instagram DM, Facebook Messenger, and the Hyperleap website widget. There is no web-only restriction — the same card payload works across all four channels.

Automation Features

AI Chatbot (RAG-Powered)

Hyperleap connects an AI chatbot to your WhatsApp number. The bot is trained on your documents, URLs, and FAQs using retrieval-augmented generation (RAG) — it answers from your content, not from a generic language model. The bot handles the conversation until it can't, then routes to a human agent with full context intact.

Message Templates

Outbound messages (outside the 24-hour service window) require pre-approved templates. Meta categorises templates into four types:

Template approval typically takes a few minutes to a few hours via Meta's automated review.

Broadcast Messaging

Send approved templates to opted-in contact lists. Broadcasts support personalisation variables (name, order number, date) inside the template body. Delivery and read rates are tracked per broadcast in the Hyperleap dashboard.

Click-to-WhatsApp Ads

Meta ads can route directly to a WhatsApp conversation. Hyperleap picks up the thread, qualifies the lead with the AI chatbot, and logs the contact — no manual handoff required. You connect your Meta ad account in the dashboard.

WhatsApp Flows

WhatsApp Flows let you build structured in-chat forms — multi-step input sequences that collect information (name, date, preference) inside the WhatsApp interface without redirecting to a browser. Common uses: appointment booking, support ticket creation, feedback collection.

Multi-Agent Inbox Features

When volume exceeds what the bot can handle, conversations land in a shared team inbox.

• • Shared inbox: all agents see the same queue; no double-handling
• • Assignment: route a conversation to a specific agent or team
• • Tags and labels: mark conversations by topic, priority, or stage
• • Internal notes: leave comments on a thread visible only to the team
• • Full conversation history: every prior message, file, and note is visible before an agent responds
• • Agent performance metrics: response time, conversations handled, resolution rate — per agent and per team

The inbox works across WhatsApp, Instagram DM, Facebook Messenger, and the website widget simultaneously. Agents do not switch tools per channel.

Channel Features

Hyperleap is a Meta-authorised Business Solution Provider. Your WhatsApp Business API number is connected via Meta's Cloud API — no on-premise hosting required. Beyond WhatsApp, the same Hyperleap workspace manages:

One knowledge base powers the AI across all four channels. Conversation history is unified per contact. You do not pay per channel — channels are included based on your plan. For a comparison of Hyperleap against other BSPs, see WhatsApp Business API providers.

Developer Features

REST API

Hyperleap exposes a full REST API. Use it to:

• • Send messages programmatically from your backend
• • Pull conversation and contact data into your CRM
• • Trigger automated sequences from external events (a payment, a form submission, a shipment update)
• • Create and update contacts

Webhooks

Real-time event notifications are sent to your endpoint on:

• • Lead created — a new contact enters Hyperleap
• • New message — an inbound message arrives on any channel
• • Reply sent — an outbound message is delivered
• • Conversation started — a new thread opens

Webhooks let you sync Hyperleap events with your CRM, data warehouse, or workflow automation tool without polling. See WhatsApp Business API integration for the patterns.

Compliance & Security Features

• • Opt-in / opt-out management — Hyperleap tracks opt-in status per contact. Opt-out requests (a user replying “STOP”) are honoured automatically.
• • End-to-end encryption — applied at the infrastructure level by Meta. Encryption is inherent to WhatsApp; no BSP can disable or bypass it.
• • Template quality rating — Meta assigns a quality rating (High/Medium/Low) per template based on user engagement.
• • Phone number quality rating — separate from template quality. A poor score restricts your messaging tier or, in extreme cases, disables outbound.

Analytics Features

• • Conversation volume: total conversations by channel, day/week/month
• • Deflection rate: percentage of conversations resolved by the AI without agent involvement
• • First response time: median time from inbound message to first reply
• • Resolution time: time from conversation open to close
• • Agent performance: per-agent response time, conversations handled, and resolution rate
• • Broadcast analytics: sent, delivered, read, and replied counts per campaign
• • Template performance: delivery rate and response rate by template

Language and Localisation Features

The AI chatbot auto-detects the language a contact writes in and responds in that language — across 100+ languages. No manual routing by language is required.

Template messages support regional language variants. A single template can have localised versions (e.g., English, Spanish, Arabic, Portuguese, Hindi) — Meta approves each locale separately. For businesses serving multilingual markets, one Hyperleap workspace handles all language variants from the same knowledge base.
