WhatsApp Business API: frequently asked questions
What is the WhatsApp Business API?
The WhatsApp Business API is Meta's official platform that lets businesses send and receive WhatsApp messages at scale, with automation, multiple agents and integrations. Unlike the free WhatsApp Business app, it has no interface of its own, so you use it through an approved provider such as TrendingBulb.
How do I get the WhatsApp Business API?
You need a Meta-approved provider. With TrendingBulb the process is: eligibility check, Facebook Business Manager setup, business verification, phone number approval, then go-live with message templates and automation. Final timing depends on Meta's verification queue, so our team gives you a current estimate before you start.
How much does the WhatsApp Business API cost?
There are two costs: the platform and Meta. TrendingBulb starts with a free trial, after which plans begin at Rs. 999 per month for bulk messaging; higher volumes and custom requirements are quoted by our team. Meta charges separately for the messages you send, at rates that vary by country and message type.
Can I use my existing WhatsApp number for the API?
Yes, as long as that number is not currently active on the WhatsApp Business app or on regular WhatsApp. If it is, you delete that account first. The number keeps working, but previous chat history does not transfer to the API.
What is the blue tick on WhatsApp and how do I get it?
The blue tick is Meta's official verification badge for business accounts, previously shown as a green tick. It is not automatic or guaranteed: Meta grants it based on how notable your brand is, including independent press coverage. TrendingBulb prepares and submits your application. Talk to our team for details on your chances and what is required.
Is bulk messaging on the WhatsApp Business API legal?
Yes, when you use Meta-approved message templates and send only to people who opted in to hear from you. That is the difference between the official API and unofficial bulk sender tools, which break WhatsApp's terms and routinely get numbers banned.
Do I need a developer to use the WhatsApp Business API?
No. The TrendingBulb dashboard handles broadcasts, chatbots and the shared team inbox without any code. Webhooks and API access are available if your team wants to build a custom integration.
