WhatsApp + SMS platform
Messaging FAQ
Straight answers on activation, branding, AI, APIs, and bulk messaging.
What is WhattNexus?
WhattNexus is an enterprise WhatsApp and SMS messaging platform — sessions, templates, campaigns, OTP, shared inbox, analytics, and developer APIs — with Nexus Brain AI for conversational automation.
Is WhattNexus available outside Pakistan?
Yes. WhattNexus serves businesses internationally — WhatsApp Business API and bulk SMS/OTP routes are available worldwide, with additional local operator options and branded SMS in Pakistan.
Do you support branded SMS?
Yes. Branded (masked) SMS and non-branded routes are available in supported markets, including Pakistan. Branded sender approval typically takes 24–48 hours with operators; WhatsApp and non-branded SMS can activate faster.
Is there an API for OTP and alerts?
Yes. REST APIs cover WhatsApp and SMS send, templates, webhooks, and delivery reporting — suitable for OTP, alerts, and product notifications.
Can agencies and resellers use WhattNexus?
Yes. Agency and reseller workflows are supported so you can manage multiple client messaging workloads from one platform.
Can I send bulk SMS and bulk WhatsApp messages?
Yes. WhattNexus supports bulk SMS and bulk WhatsApp messaging with templates, personalization, and delivery reporting — sized for lists from a few hundred to millions of contacts.
What is the WhatsApp Business API?
The WhatsApp Business API (including Cloud API paths) lets businesses send and receive WhatsApp messages at scale — templates, notifications, and support chats — instead of relying on a personal phone. WhattNexus wraps that capability with inbox, campaigns, session health, and SMS OTP in one platform.
Do I need WhatsApp template messages for bulk sends?
For most outbound bulk WhatsApp messaging outside an open customer-care window, approved template messages are required. WhattNexus helps you manage templates, variables, and campaign sends with delivery visibility.
What is a WhatsApp chatbot and do you support AI replies?
A WhatsApp chatbot automates FAQs, lead capture, and routine support, then hands off to humans when needed. WhattNexus includes Nexus Brain AI for context-aware draft replies inside a shared inbox — so automation does not erase conversation history.
Is WhattNexus a WhatsApp CRM?
WhattNexus provides WhatsApp CRM-style workflows: shared inbox, conversation history, session awareness, and AI-assisted replies for sales and support teams — without forcing chats to live on one employee’s personal phone.
How is WhattNexus different from WhatsApp Cloud API alone?
Cloud API is the messaging pipe. WhattNexus is the operations layer — multi-session management, shared inbox, campaigns, analytics, branded SMS/OTP, and developer APIs — so marketing and support can run day-to-day without building every tool from scratch.
Can I use WhattNexus as an SMS gateway API?
Yes. Use the SMS gateway API for transactional OTP, alerts, and bulk SMS campaigns, with delivery reports and webhook-friendly status flows suitable for product and ops teams.
Do you support SMS masking in Pakistan?
Yes. Branded SMS (masking) is available for Pakistan operator routes. Approval commonly takes 24–48 hours. Non-branded SMS and WhatsApp can often activate faster while masking is pending.
Can ecommerce brands send abandoned cart WhatsApp messages?
Yes. Trigger WhatsApp template messages from your store or backend via API for abandoned carts, order updates, and delivery notifications — then continue the conversation in the shared inbox when customers reply.
Do you support webhooks for delivery and inbound messages?
Yes. Webhooks can deliver send status and inbound events so your systems can update orders, close OTP loops, and sync CRM records without polling.
Can multiple agents share one WhatsApp number?
Yes. The shared WhatsApp inbox is built for teams — multiple agents work from one conversation history with session health visibility, instead of forwarding screenshots from WhatsApp Web.
Is there a free trial?
Yes. WhattNexus offers a trial path so you can connect a session, test templates or OTP, and evaluate inbox and campaign workflows before you commit to production volume.
Which programming languages work with the API?
Any language that can make HTTPS requests works — including Node.js, Python, PHP, Java, Go, and C#. Official samples and console tools help you debug payloads quickly.
Can hospitals and clinics send appointment reminders?
Yes. Clinics and hospitals use WhatsApp and SMS appointment reminders with API hooks into scheduling or HMS software, plus a shared inbox for reschedule replies.
How do I choose between bulk SMS and bulk WhatsApp?
Use bulk SMS for time-critical OTP and offers that must reach any phone. Use bulk WhatsApp for richer conversations, support, and high-engagement marketing where customers already chat. Many teams run both on WhattNexus.
