Connecting WhatsApp Business API: A Complete Guide for Businesses

Connecting WhatsApp Business API means integrating the official Meta API with your business systems to automate customer communication. With WazzaBee you get access to the official WABA with the blue checkmark, HSM templates and broadcast messaging.

According to Meta, more than 2 billion people use WhatsApp every month, and businesses in Kazakhstan increasingly work with customers through messengers.

What WhatsApp Business API is and why your business needs it

WhatsApp Business API (WABA) is Meta's official solution for using WhatsApp at company scale. Unlike the regular WhatsApp Business app, the API lets you connect the messenger to CRM systems and automate your processes.

What is WABA? WhatsApp Business API is a programming interface that lets a business integrate WhatsApp with its internal systems, send notifications to customers and process incoming messages automatically.

Key benefits of the official API

• Blue verification checkmark: builds customer trust

• HSM templates: Meta-approved templates for broadcasts

• CRM integration: all messages in one window together with the customer history

• Automation: chatbot, auto-replies, request routing

• Analytics: detailed delivery and read statistics

The official WhatsApp Business API raises the conversion of incoming requests thanks to instant replies and personalized messages. Customers trust accounts with the blue checkmark more.

How it differs from the regular WhatsApp Business app

Requirements for connecting WhatsApp Business API

To connect WABA through WazzaBee, you need to meet Meta's official requirements and prepare your company documents.

Documents for business verification

• Certificate of state registration: issued within the last 6 months

• Tax registration certificate: confirms the company is active

• Document appointing the director: an order or the company charter

• Bank details: a bank letter or statement

• Company website: must include a privacy policy

Technical requirements

1. Phone number: a new one or your current one. A current number that runs the WhatsApp Business app is connected in Coexistence mode through a WazzaBee manager

2. Facebook Business Manager: a company account (not a personal one)

3. CRM access: to set up the integration

4. Responsible person: an administrator with signing authority

Most WABA verification rejections come from incorrectly prepared documents or from using personal accounts instead of company ones. WazzaBee helps you prepare the document package correctly the first time.

Integrating WhatsApp Business API with CRM systems

WazzaBee supports direct WABA integration with three types of CRM systems through official APIs, with no loss of functionality.

Bitrix24 integration

Bitrix24 is connected through OAuth authorization and installing the app from the marketplace:

1. Install the WazzaBee app from the Bitrix24 Marketplace

2. Authorize via OAuth (permissions: crm.lead, im.chat)

3. Set up automatic lead creation from incoming messages

4. Activate Open Line to chat right in deal cards

amoCRM integration

The amoCRM connection uses the Chats API with an HMAC-SHA1 signature:

1. Get an API key in the amoCRM settings

2. Set up a webhook for incoming messages

3. Activate automatic creation of contacts and deals

4. Link chats to your sales pipelines

Universal integration via REST API

For other CRM systems, the WazzaBee REST API is available: sending messages and templates, conversation history, contacts and webhooks. A message is sent with a POST request to https://api.wazzabee.com/api-gateway/v1/messages/send with the Authorization: Bearer header and your API key. Request fields and examples are in the API documentation.

Integrating WABA with a CRM speeds up request handling. Agents see the full customer history and can reply right from the deal card without switching between systems.

HSM templates and broadcasts

HSM (Highly Structured Message) templates are message formats pre-approved by Meta for broadcasts through WhatsApp Business API.

What are HSM templates?

HSM templates are structured messages with fixed text and variables that go through Meta moderation before use. Without approved templates, broadcasts through WABA are not possible.

Types of HSM templates

Creating and moderating templates

1. Create in WazzaBee: a builder with preview

2. Submit for moderation: sent to Meta automatically

3. Wait for approval: Meta sets the review time

4. Activation: the template becomes available for broadcasts

Setting up broadcasts

• Audience import: CSV/Excel files with numbers

• Segmentation: filters by city, interests, purchases

• Personalization: variables {{name}}, {{company}}, {{amount}}

• Scheduling: delayed sending at the best time

• Analytics: delivery, read and click statistics

WhatsApp Business API pricing

The cost of using WABA is made up of the monthly WazzaBee subscription and payment for messages at Meta rates.

• Included: unlimited conversations, CRM integrations

• Bonus: starting balance for WABA messages

• Discounts: 6 months −10%, 1 year −20%

• Utility: invoices, notifications ($0.0286 per message)
