Nexus + WhatsApp Business API: Official, Scalable, Ops-Ready
Nexus integrates with the official WhatsApp Business API — not the unofficial scraping-based tools. You get a compliant, scalable WhatsApp inbox with AI signal tagging, team routing, SLA enforcement, and campaign broadcasting, all connected to your orders and CRM.
What This Integration Does
Connecting WhatsApp Business API to Nexus gives your team a production-grade messaging infrastructure that scales from 10 messages a day to millions. Every inbound WhatsApp message lands in a shared inbox where agents can be assigned, SLAs are tracked, and AI automatically surfaces urgency and intent. Outbound campaign broadcasting uses Meta-approved templates, so your messages reach customers without spam risk. The entire channel — inbound, outbound, and broadcasts — is unified with your order data and CRM so your team never has to context-switch to answer a customer question.
Official API connection
WABA-compliant connection using Meta's official Cloud API. No account ban risk, no unofficial scraping, full access to message templates and broadcast capabilities approved by Meta.
AI-enhanced inbox
Every inbound message is automatically tagged with intent (order query, complaint, return request), urgency level, and sentiment — so agents triage at a glance and managers can spot patterns across thousands of conversations.
Broadcast campaigns
Send approved template messages to segmented customer lists: post-purchase follow-ups, reactivation campaigns, shipping alerts, and promotions — all from the Nexus campaign builder with delivery and open tracking.

If you're starting from scratch, Nexus onboarding includes guided WABA setup. Once connected, your team can start receiving and responding to WhatsApp messages immediately — no technical configuration required beyond the initial OAuth connection.

Frequently Asked Questions
Does Nexus use the official WhatsApp Business API or an unofficial tool?
Nexus uses only the official WhatsApp Business API (WABA). This means your WhatsApp number is fully compliant with Meta's policies, you can use approved message templates, and you will not risk account bans that come with unofficial API tools. Many low-cost WhatsApp tools use browser automation or unofficial scraping — those accounts are regularly banned by Meta. Nexus's WABA connection is built for production at scale.
What is the difference between WhatsApp Business App and the WhatsApp Business API?
The WhatsApp Business App is designed for small businesses and only supports one user at a time on one device. There is no team inbox, no API access, and no broadcast capability beyond very limited broadcast lists. The WhatsApp Business API supports unlimited agents, message templates approved by Meta, broadcast messaging to segmented lists, and full programmatic access — which is what Nexus uses to power your inbox and campaigns.
Can I keep my existing WhatsApp number when connecting to Nexus?
Yes. You can migrate an existing WhatsApp Business number to the API. The migration process verifies the number with a one-time SMS or voice code and transfers your display name, profile photo, and business description. Note: once a number is migrated to the WABA, it can no longer be used on the WhatsApp Business App simultaneously. Your Nexus onboarding specialist will walk you through the migration.
What message templates does Nexus support?
Nexus supports order confirmation, shipping update, delivery confirmation, and customer follow-up templates out of the box — these are pre-built and ready to submit for Meta approval. Custom templates can be created in the Nexus dashboard with your own copy, variables, and call-to-action buttons, then submitted to Meta for approval directly from Nexus. Template approval from Meta typically takes a few minutes to a few hours.
Is there a limit on how many WhatsApp messages I can send?
Message limits are set by Meta based on your account quality tier. New accounts start at 1,000 unique recipients per 24 hours. As you maintain a high quality rating (low block rates, good template engagement), the limit increases automatically to 10,000, then 100,000, then unlimited. Nexus monitors your quality rating and manages sending rate to keep you within limits — and alerts you if your quality rating drops so you can take corrective action before limits are reduced.
