WhatsApp Business API integration
The WhatsApp Business API, now delivered as Meta's Cloud API, lets an organisation send and receive WhatsApp messages from its own systems at scale. Arke Technologies in Johannesburg sets it up for organisations, public bodies and schools across South Africa, connects it to your CRM, service desk or chatbot, and supports it under an SLA.
What is the WhatsApp Business API?
The WhatsApp Business API is Meta's programmable interface to WhatsApp for organisations that need more than one phone can handle. Your CRM, service desk, booking system or chatbot sends messages through the API and receives replies through webhooks. Meta calls the product the WhatsApp Business Platform. Meta's WhatsApp Cloud API is the version Meta hosts, and it is the standard route now that the older self-hosted On-Premises API has been retired.
A WhatsApp Business API account (formally a WhatsApp Business Account, held in your Meta business portfolio) carries your verified profile, phone numbers and approved message templates. It should be registered to your organisation, never to the developer.
Searches for "api whatsapp com" usually mean the click-to-chat address api.whatsapp.com/send (or wa.me), which opens a chat from a website button or QR code. It is free and useful, but it is a link rather than an integration: nothing reaches your systems.
What organisations use it for
The WhatsApp Business API features that matter most are message templates, interactive buttons and lists, media and documents, and structured forms (WhatsApp Flows). Organisations use them for:
Authentication
One-time passcodes for sign-in and payments.
Customer service
A shared inbox that routes chats, keeps history on the customer record and hands over between bot and agent.
Chatbots
Answers, bookings and status checks outside office hours.
Marketing
WhatsApp Business API for marketing means templates sent only to customers who opted in, with opt-outs honoured at once.
Schools can use it for parent notices and fee statements, and municipalities for service requests and outage updates.
WhatsApp chatbots and AI automation
A WhatsApp chatbot can be a simple menu or an AI assistant that answers in plain language from your own content and systems. For WhatsApp AI automation we build with models from Anthropic (Claude) and Google (Gemini, through Vertex AI), with guardrails, logging and cost controls.
We build each WhatsApp Business API bot with three modes: off, draft (staff approve each reply) and automatic, the approach we use for the customer assistant on our own Server Hub platform. Start in draft, measure accuracy, then automate only what the bot answers well; a person can always take over. Meta's terms restrict general-purpose AI assistants on WhatsApp, so we design bots that answer your own customers' questions and check the current policy during design. See chatbots and conversational AI and AI automation.
How the API sends and receives messages
To send, your system calls the WhatsApp message API with the recipient and either free-form content or an approved template. Inside the 24-hour customer service window, which opens when a customer messages you, you may reply freely; outside it, every message you send through the API must be an approved template.
To get messages, the WhatsApp API uses webhooks: Meta pushes each incoming message, and each delivery and read status, to an endpoint you host. There is no mailbox to poll, so we build the endpoint with signature checks, queues and retries that lose nothing on a busy day.
Quality matters as much as code. Daily messaging limits start low and rise while your quality rating stays high; blocks and reports pull it down, so we design templates and opt-in flows to keep it healthy.
Connecting WhatsApp to your CRM, service desk and website
WhatsApp business integration is where the value sits. We connect the WhatsApp integration API to:
Your CRM
A CRM with WhatsApp integration logs each conversation against the contact in Salesforce, HubSpot or Zoho, and triggers templates from CRM events.
Your service desk
Chats become tickets with SLA clocks.
ERP and accounting
Order status, statements and invoices from the system that holds them.
Payments
PayFast or Yoco payment links, with confirmation posted to the chat and the ledger.
Compliance workflows
Filing reminders and document requests raised by the systems that track SARS and CIPC deadlines.
Moving from a BSP's tool to the Cloud API? Your WhatsApp Business Account can move with you, and opt-in records and conversation history that the old tool can export are moved as a planned data migration.
POPIA, consent and message records
- Opt-in first. We record where and when each customer opted in, honour opt-outs at once, and follow POPIA section 69 for direct marketing.
- Cross-border processing. Messages pass through Meta's infrastructure outside South Africa, so the flow is documented for POPIA section 72 and your privacy notice.
- Minimal content. No identity numbers or health details in templates; sensitive detail sits behind an authenticated link.
- Records and backup. The WhatsApp app's cloud backup to Google Drive or iCloud does not apply to the API. History lives in the systems you connect and is backed up with them; see backup and disaster recovery.
- Security. Tokens in a vault, webhook signatures verified, least-privilege access and audit logs.
Governance, compliance, procurement and continuity
- Governance and reporting. A named lead, template and flow changes under change control, a written escalation path, and an SLA with a monthly service review and report on volumes, delivery failures, quality rating and cost by category.
- Compliance. POPIA by design, with a section 21 operator agreement where we process personal information for you, ISO/IEC 27001-aligned controls, and audit logs that support King IV Principle 12 reporting and PFMA or MFMA audit.
- Procurement. Level 1 B-BBEE contributor (sworn affidavit available on request), giving buyers 135% procurement recognition. Company documents, CSD supplier number and tax compliance status are available on request, and we complete SBD forms when a bid requires them. Buy by proposal, SLA and purchase order, or by tender; see company facts.
- Continuity. Your Meta business portfolio, WhatsApp Business Account, numbers and templates are registered to your organisation, with your staff as administrators. We hold only the access you grant, and you keep the code, documentation and message history, so the channel stays up if you change provider or bring the work in-house.
