Nexus + WhatsApp Business API: Official, Compliant, Operational
Nexus connects to WhatsApp through Meta's official Business Platform API — not scraping, not third-party workarounds. Your business number plugs into Nexus's unified inbox, CRM, and automation engine, so your entire team can work from a single compliant WhatsApp operation without juggling multiple phones or apps.
What This Integration Does
Most businesses outgrow WhatsApp Business App the moment they hire a second customer service agent — the app was designed for a single user on a single device. The WhatsApp Business API removes that constraint entirely. Nexus uses the official Meta-hosted API to give your team a shared, structured inbox where multiple agents handle conversations simultaneously on one number, routing rules assign incoming chats automatically, and every conversation is stored, searchable, and linked to a CRM profile. On top of that, Nexus layers AI tagging to classify buying intent, complaints, and urgency the moment a message arrives, so no conversation falls through the cracks regardless of volume.
Multi-agent shared inbox
Every agent on your team accesses the same WhatsApp number through Nexus. Conversations are assigned by routing rules or manually, internal notes are threaded alongside customer messages, and supervisors can monitor the full queue in real time — all without sharing a phone or a login.
Template management & broadcasts
Submit, manage, and send Meta-approved message templates directly from Nexus. Build broadcast lists from CRM segments, schedule sends, and track delivery and read receipts per recipient. Nexus alerts your team when the 24-hour service window is about to close on any open conversation.
AI tagging & CRM linking
Every incoming WhatsApp message is automatically classified by Nexus's AI — intent, sentiment, urgency, and topic — and the conversation is linked to the matching CRM contact. Agents open a chat and instantly see the customer's full history, previous orders, and outstanding issues without asking for a name or order number.

Frequently Asked Questions
Is this the official WhatsApp Business API or a scraping workaround?
Nexus uses the official Meta-hosted WhatsApp Business Platform API exclusively. There is no scraping, no browser automation, and no unofficial access. Your number is registered directly through Meta Business Manager and all messaging occurs through Meta's infrastructure, keeping your account compliant and your data secure. Unlike grey-market tools that risk permanent number bans, Nexus is a Meta Business Solution Partner.
Can multiple agents handle conversations on the same WhatsApp number?
Yes. The WhatsApp Business API supports a single business number accessed by unlimited team members simultaneously. Nexus routes conversations to agents using assignment rules, round-robin distribution, or manual assignment by a supervisor. Every agent sees only their assigned conversations, and supervisors can view, monitor, and reassign the full queue at any time — all from the same shared inbox.
Are message templates required for all outgoing messages?
Templates are required only to initiate a new conversation outside the 24-hour customer service window — these are called template messages or HSMs (Highly Structured Messages). Once a customer replies and opens a conversation, a free-form 24-hour window opens and your agents can send any message without a template. Nexus manages both flows automatically and alerts agents when a conversation is approaching its window expiry so they can follow up in time.
Can I send broadcast messages to my contact list?
Yes. Nexus lets you build broadcast lists from your CRM contacts, apply segment filters (e.g., all customers with an open order, or all contacts tagged "VIP"), select an approved message template, and send at scale. Delivery and read receipts are tracked per recipient. Broadcast sending respects Meta's messaging tier limits, which increase automatically as your account builds a positive quality rating over time.
Is the integration compliant with Meta's WhatsApp Business policies?
Yes. Because Nexus uses the official API, all messaging is fully compliant with Meta's WhatsApp Business Policy and Commerce Policy. Nexus does not support or enable unsolicited messaging, and all outbound template messages require Meta's pre-approval before they can be sent. Your business phone number retains its quality rating and messaging tier as long as you follow Meta's guidelines and maintain low block rates.
