WhatsApp AI Chatbot

In the Gulf, South Asia, Latin America and much of Europe, WhatsApp is the default business channel. It also has rules that shape what you can build.

The problem

The rules that shape the build

WhatsApp is not email. Understanding the constraints before design saves an expensive rebuild.

Outside a 24-hour customer-initiated session window, you can only send pre-approved template messages, and templates take time to get approved and must fit defined categories. Inside the window, free-form conversation is allowed. Pricing is per conversation, categorised by whether it is marketing, utility, authentication or service.

Opt-in must be recorded before you message anyone, and quality ratings fall if recipients block or report you — which restricts your sending limits. We design the conversation flow around these mechanics rather than discovering them at launch.

  • Opt-in captured and recorded before the first message
  • Template library designed and submitted early for approval
  • Session-window logic handled automatically in the flow
  • Conversation-category pricing modelled before launch
  • Quality rating monitored with alerting
  • Media, location and interactive buttons used where they reduce turns
  • Human handoff into a shared agent inbox

How we deliver

Ten stages from first call to a system your team trusts

Every AI engagement runs this sequence. Small projects compress stages; regulated projects expand them. Nothing gets skipped silently.

Discovery

A working session with your operations and engineering leads to map the process, the systems it touches, and where the cost actually sits.

AI Opportunity Assessment

We score candidate use cases on data readiness, volume, error tolerance and payback, then rank them. Some come back "do not use AI for this" — you get that answer too.

Solution Architecture

Model selection, retrieval design, tool boundaries, data flow, failure modes and hosting topology, documented before code.

Proof of Concept

A narrow build against your real data to prove accuracy on the cases that matter, typically 2–4 weeks. Go / no-go decision at the end.

MVP

One workflow, end to end, in the hands of real users. Evaluation sets and quality thresholds are defined here, not retrofitted.

Production Development

Hardening: error handling, retries, fallbacks, cost controls, rate limits, observability, and a human escalation path for every automated decision.

Integration

Wiring into your CRM, ERP, HRMS, data warehouse, ticketing and messaging channels through APIs, webhooks and event queues.

Security Testing

Prompt-injection testing, access-control verification, PII handling review, dependency scanning and penetration testing before go-live.

Deployment

Staged rollout on your cloud or ours, with CI/CD, versioned prompts and models, and rollback in place from day one.

Monitoring & Optimization

Quality dashboards, drift detection, cost-per-transaction tracking and a retraining or re-prompting cadence agreed in writing.

Security & Governance

Security-conscious architecture, from the first design review

Enterprise AI fails on governance more often than on models. Every system we build is designed to support enterprise security requirements and to give your risk team answers rather than assurances.

Data privacy & residency

Your data stays in the region and tenancy you nominate. We architect for no-training-on-your-data configurations and document exactly which vendor endpoints see which fields.

Role-based access control

Retrieval and tool permissions inherit your existing roles. A user cannot surface a document through the AI that they could not open directly.

Authentication & authorization

SSO via OIDC/SAML, short-lived tokens for agent tool calls, and per-tool scopes so an agent holds the narrowest possible privilege.

Encryption

TLS in transit, AES-256 at rest, managed keys via your cloud KMS, and encrypted vector stores for embedded content.

API security

Gateway-level authentication, signed webhooks, IP allowlisting, request validation and quota enforcement on every exposed endpoint.

Audit logging

Every prompt, retrieval, tool call, model version and human override is logged with a trace ID, so any output can be reconstructed months later.

Data isolation

Per-tenant separation at the storage, index and key level for multi-entity groups and regulated environments.

Secure prompt handling

System instructions are server-side, user content is treated as untrusted input, and we test against prompt-injection and tool-abuse patterns.

PII protection

Detection, masking or tokenisation of personal data before it reaches a model, with configurable redaction policies per field.

Human approval workflows

High-impact actions — payments, refunds, contract sends, record deletion — route to a named approver instead of executing autonomously.

Monitoring & anomaly detection

Alerting on unusual tool usage, cost spikes, refusal rates and quality regressions.

Rate limiting & abuse control

Per-user and per-tenant throttles, spend caps and circuit breakers so a runaway loop cannot become a runaway invoice.

Secure deployment

Private networking, secrets in a managed vault, immutable builds, dependency scanning, and infrastructure as code.

FAQ

Questions enterprise buyers ask us first

What does WhatsApp Business API cost?
Meta charges per conversation, with rates varying by country and conversation category — marketing, utility, authentication or service. Business Solution Providers add their own fee. We model your expected volume by category during scoping so the running cost is known before you build, since it is often the largest ongoing line item.
Why can we not message customers whenever we want?
Outside a 24-hour window opened by the customer, only pre-approved template messages may be sent, and only to contacts who have opted in. It is a deliberate anti-spam design. We build the template library and opt-in flow as part of the project.
Can a human take over the conversation?
Yes. The AI handles the conversation until a handoff trigger fires, then it moves to a shared agent inbox with full history. The customer experiences one continuous thread.
Can it handle images and documents?
Yes — receiving photos of damaged goods, ID documents or invoices, and sending images, PDFs, location and interactive buttons. Received documents can be validated and extracted automatically.
