WhatsApp Business API Integration: How to Connect WhatsApp to Your Stack (2026)

TL;DR — Integration Paths at a Glance

Four Integration Paths

1. Webhooks — Real-Time Event Streaming

Webhooks are the fastest way to wire WhatsApp events into any system. When something happens in a Hyperleap conversation — a new lead, an inbound message, an agent reply — Hyperleap immediately POSTs a signed JSON payload to your endpoint.

This is the right path when you need low-latency event handling: logging conversations to your data warehouse, triggering a CRM record creation, routing a high-intent lead to your sales queue, or kicking off an automated follow-up sequence.

Hyperleap signs every webhook delivery so you can verify authenticity on your end. Implement idempotency on your receiver — Hyperleap may retry deliveries on timeout, so your handler should deduplicate by event ID.

2. REST API — Query and Act

The REST API gives you pull-based access and write capabilities. Use it to query leads and conversations, retrieve message history, send outbound messages, and manage approved message templates.

This is the right path when you need to initiate actions from your system — not just react to events. A support agent resolves a ticket in your helpdesk and your system sends a closing WhatsApp message. A sales rep qualifies a lead in your pipeline and triggers a follow-up template. All of that happens via API call, not by waiting for a webhook. Full reference at /whatsapp-business-api/documentation.

3. Website Embed — Chat Widget on Your Site

Hyperleap's chat widget is a JavaScript snippet you add to any web page. When a visitor starts a conversation on your website, that conversation is a WhatsApp thread — your team handles it inside Hyperleap's inbox, and the visitor's WhatsApp receives the replies.

The embed is not a direct WhatsApp API integration — it is a channel connection where the web surface feeds into the same WhatsApp inbox as your direct WhatsApp contacts.

4. BSP Middleware — Hyperleap as Your WhatsApp Layer

As a Meta-authorised BSP, Hyperleap manages the underlying Meta Cloud API connection on your behalf. You do not interact with Meta's Graph API directly — Hyperleap handles phone number provisioning, template approval submissions, message quality monitoring, and rate-limit management. Your application talks to Hyperleap's REST API and webhooks. Hyperleap handles everything between your stack and Meta. See the Cloud API overview for more on what the BSP layer handles.

Webhook Events Hyperleap Fires

Configure your webhook endpoint in the Hyperleap dashboard under Settings → Integrations → Webhooks. Hyperleap will POST to your URL for these four events:

All payloads are JSON. Each delivery includes a signature header for verification. Your endpoint must return 2xx within the timeout window, or Hyperleap retries with exponential backoff. Full webhook payload schemas are documented at /whatsapp-business-api/documentation.

REST API

The Hyperleap REST API covers four capability areas:

• • Leads: List, filter, and retrieve lead records with contact details and source attribution.
• • Conversations: Read full message threads by lead or conversation ID.
• • Messages: Send outbound messages to existing contacts (subject to Meta's 24-hour messaging window and template rules).
• • Templates: List your approved message templates and their status.

Auth model: Bearer token, issued per workspace in the Hyperleap dashboard. Include the token in the Authorization header on every request. The API is RESTful and returns JSON. Pagination is cursor-based.

Website Embed

The Hyperleap chat widget embeds on any web platform via a JavaScript snippet. Supported platforms:

CRM Integration

Current state: Connect via REST API and webhooks — no native CRM integration is shipped today.

The practical pattern:

1. Configure a lead.created webhook to fire to your integration layer.
2. Your handler maps the Hyperleap lead payload to your CRM's contact schema and creates or updates the record.
3. Use the REST API to push conversation notes or messages back from your CRM's context.

If you are using a middleware platform (Make, n8n, or similar), you can connect Hyperleap webhooks as the trigger node and your CRM as the target — no custom code needed.

What's coming: Native HubSpot, Salesforce, and Zendesk integrations are in active development. These will provide two-way sync without a custom integration layer. They are not shipped yet and do not have a confirmed release date.

Booking Systems

Hyperleap does not integrate natively with Calendly or Cal.com via their APIs. What it does: when a lead expresses intent to book, the AI agent shares your Calendly or Cal.com booking link in the WhatsApp conversation. The customer taps the link and completes their booking in the browser.

The result is the same from the customer's perspective — they get from WhatsApp conversation to confirmed appointment. But there is no two-way API sync: Hyperleap does not know when the booking is confirmed, and it does not write back to your calendar. If you need that data, set up a Calendly or Cal.com webhook on your end and connect it to your CRM or Hyperleap via your own integration layer.

E-Commerce Integration

Hyperleap embeds on Shopify and WooCommerce sites as a chat widget (see Website Embed above). This is a customer conversation layer — it does not connect to the Shopify Admin API for product browsing, cart management, or order status lookups.

If you want to provide order status or product information through the Hyperleap agent, the current path is:

1. Set up a Shopify webhook that fires on order events (created, fulfilled, updated).
2. Your integration layer receives the Shopify event and calls the Hyperleap REST API to send the relevant data to the customer's WhatsApp conversation.

This requires custom development. It is not a native feature. Deeper e-commerce connectivity is a planned direction, not a current capability.

Custom Integrations

The general architecture for a custom Hyperleap integration:

[Hyperleap] --webhook--> [Your endpoint] --transforms data--> [Your system]
                                     ^
[Your system] --REST API call--------|
                    (send message, read lead, fetch conversation)

Real-time inbound data flows via webhooks. Your system initiates actions via REST API. This covers the majority of integration requirements: CRM sync, helpdesk routing, notification services, data pipelines, and outbound messaging triggered by your backend logic.

For more complex orchestration — conditional routing, multi-step workflows, retry logic — wrap your webhook handler in a lightweight queue (SQS, Pub/Sub, or a similar message broker) to decouple ingestion from processing. Full feature overview: /whatsapp-business-api/features.

Middleware Integrations (Zapier, Make, n8n)

Zapier: Native Zapier integration is in active development. It is not available today. Do not build a production workflow that depends on it being available on a specific date.

Make and n8n: Hyperleap webhooks work as trigger nodes in Make and n8n today. Configure a webhook receiver module in Make or n8n, point your Hyperleap webhook at that URL, and connect any downstream action — CRM updates, Slack notifications, spreadsheet logging, email sequences. This requires no code.

This is a practical path while native integrations are in development. The limitation is that Make/n8n cannot initiate actions back to Hyperleap via a pre-built module — you would use Hyperleap's REST API with an HTTP action module for that.
