Connect WhatsApp with every part of your business
Integrate customer communication into your CRM, ecommerce store, helpdesk, ERP and internal systems using the LandinChat WhatsApp API platform — built on Meta Cloud API.
Why businesses outgrow basic WhatsApp
Personal WhatsApp and the Business app weren't built for operations. Here's where they break.
Manual messaging
Reps copy-paste from spreadsheets into WhatsApp Web. No tracking, no audit trail.
Disconnected systems
CRM, ERP, helpdesk and store all live in silos. WhatsApp is yet another silo.
No automation
Order placed in Shopify ≠ WhatsApp confirmation. Every notification is human-triggered.
Data silos
Customer conversation history never reaches the CRM. Sales can't see support history.
Operational bottlenecks
Ops scales by hiring. Volume doubles → headcount doubles → margins collapse.
No visibility
Which messages convert? Which templates fail? Personal WhatsApp has zero analytics.
The modern business communication stack
WhatsApp becomes the communication layer that sits between your customers and every system you run.
Popular WhatsApp API use cases
Across sales, support, ops and security — wherever notifications, confirmations or two-way conversations matter.
Lead Notifications
Instant WhatsApp ping to the right rep when a form, ad or chatbot captures a lead.

WhatsApp API — 30 questions answered
What is the WhatsApp API?
The WhatsApp Business API (now Cloud API) is Meta's programmatic interface for sending and receiving messages at business scale — with templates, webhooks, two-way conversations and multi-agent support that the consumer app doesn't offer.
What is the difference between WhatsApp API and WhatsApp Business app?
The Business app is for small businesses on a single phone. The API is for organisations that need to integrate WhatsApp into CRM/ERP/ecommerce systems, send at high volume, use bots, and let multiple agents reply.
Is LandinChat a WhatsApp API provider?
Yes — LandinChat is an Official Meta Tech Partner and provides the WhatsApp Business Platform with a hosted Cloud API setup, integrations, no-code tools and a multi-agent inbox.
What is the WhatsApp Cloud API?
Cloud API is Meta's officially hosted version of the WhatsApp Business API. LandinChat onboards your number on Cloud API so you don't have to host or maintain infrastructure.
How long does it take to get a WhatsApp API account?
Most businesses go live in under 24 hours. The bottleneck is usually Meta Business verification, which we guide you through.
Do I need a developer to use the WhatsApp API?
No. LandinChat provides a no-code dashboard for non-technical teams. Developers can use our REST API, webhooks and SDKs when they need deeper integration.
Can I keep my existing WhatsApp number?
If the number is on the WhatsApp Business app you can migrate it. If it's on the consumer app you'll need to delete that account first or use a new number.
Will I get the green tick?
The green tick is granted by Meta based on brand notability. LandinChat helps eligible businesses apply for official business verification.
How is WhatsApp API pricing structured?
Meta charges per conversation (24-hour window) by category and country. LandinChat charges a flat monthly platform fee and passes Meta charges through at cost — no per-message markup.
What is a WhatsApp template message?
A pre-approved message format used for proactive outbound communication (notifications, marketing). Templates are approved by Meta and support variables, buttons and media.
What categories of templates does WhatsApp support?
Marketing, Utility and Authentication. Each has different pricing and approval rules.
Can the WhatsApp API integrate with my CRM?
Yes. LandinChat has native integrations for Salesforce, HubSpot, Zoho, Pipedrive, Microsoft Dynamics and more, plus an open REST API for custom CRMs.
Can I connect my Shopify store to the WhatsApp API?
Yes. Cart abandonment, order updates, shipping notifications and review requests can all be wired to Shopify, WooCommerce, Magento and BigCommerce.
Can I send OTPs over WhatsApp?
Yes. Authentication templates support one-time password delivery — typically with higher delivery rates and lower cost than SMS.
What webhooks does the WhatsApp API support?
Inbound messages, message status (sent, delivered, read, failed), template status changes, and account events.
How does the 24-hour customer service window work?
Once a user messages you, you have 24 hours to reply with free-form messages. Outside that window you must use an approved template.
How many agents can use the inbox?
Unlimited. LandinChat does not charge per-agent fees, regardless of plan.
Does the API support media — images, PDFs, videos?
Yes — images, videos, PDFs, audio, location, contacts and interactive buttons or lists.
What are the message rate limits?
Cloud API tiers start at 1,000 unique customers/24h and scale automatically to unlimited as quality remains high.
Is the WhatsApp API secure?
All transport is TLS 1.2+. Messages are end-to-end encrypted between WhatsApp clients and Meta. LandinChat is SOC 2 aligned and GDPR & DPDP compliant.
Does it work outside India?
Yes. LandinChat serves customers across India, the US, UK, UAE, Brazil, Indonesia and 20+ markets, with local currency billing.
Can multiple departments share one number?
Yes. Routing rules direct inbound conversations to the right team (sales, support, billing) automatically.
Can I send broadcasts to thousands of customers?
Yes — segmented broadcasts of approved templates to lists of any size, with delivery and read analytics.
What's the difference between Cloud API and On-Premise API?
Cloud API is hosted by Meta (recommended). On-Premise was hosted by partners and is being deprecated by Meta in 2025.
Can I run AI chatbots on the WhatsApp API?
Yes — combine LandinChat flows with any LLM (OpenAI, Anthropic, Gemini) to run grounded AI assistants on WhatsApp.
Does LandinChat support international SMS-style use cases (OTP, alerts)?
Yes. Authentication and Utility templates cover OTP, transaction alerts and account notifications globally.
Can I export conversations and analytics?
Yes — CSV exports, scheduled reports and webhook event streaming to your data warehouse.
What happens if Meta rejects a template?
We surface the rejection reason and suggest fixes. Most rejections are formatting or category mismatches, fixable in minutes.
Is there a free trial?
View current plans and trial details on the pricing page.
