Frequently Asked Questions
What is WhatsApp Business API?
The WhatsApp Business API (also known as the WhatsApp Business Platform) enables medium to large companies to automate and scale messaging with customers via WhatsApp. It supports automated workflows, templates, integration with CRMs/chatbots, analytics, and multi-agent access, unlike the standard Business App.
How to get access to WhatsApp API to send messages?
Firstly, apply from a WhatsApp Business Solution Provider (BSP). Then, get approved for your Business account and phone number. Next, use either the Cloud API (no hosting needed) or On-premise API (self-hosted) to obtain credentials (API key, phone number ID). Finally, integrate using the provided endpoints to send messages.
What is WhatsApp API pricing?
WhatsApp charges per 24-hour conversation based on type and region. In Malaysia, the fee for utility (business-initiated) is charged at around US$0.014, authentication template at around US$0.018, marketing template at around US$0.086 and user-initiated (free within 24h) at around $0.022. Do take note that BSPs also charge platform/subscription fees. For detailed information, please check on official Meta website.
How to use WhatsApp API to send messages?
You send messages through API endpoints, e.g., POST /v13.0/{{PHONE_NUMBER_ID}}/messages with a JSON payload. Templates must be pre-approved and used for business-initiated messages. Implementation typically involves SDKs or HTTP clients.

Is WhatsApp API free to use?
Accessing the API itself is free, but message sending incurs charges per conversation, and BSPs often charge fees for access and platform use.
How to make WhatsApp API by myself?
You can self-host using the On-premise API. Here is guide. Firstly, host WhatsApp's Docker containers, register phone via Facebook Developer settings, obtain credentials (tokens, phone ID) & implement sending/receiving endpoints, but most opt to use BSPs or the Cloud API due to complexity.
How to call WhatsApp API?
Use HTTP POST requests to API endpoints (e.g., /v13.0/<PHONE_ID>/messages), with JSON payload specifying recipient, template or text/media content, and your access token. Most BSPs and SDKs abstract these details.

Do I need a developer to use the WhatsApp API?
For basic usage, like sending bulk messages and managing contacts through the Yaeris dashboard, no coding is required. For deeper integrations, such as connecting the API to your own CRM or building automated chat flows, some development work is needed. Yaeris can advise on integration support options for businesses without in-house developers.
