There are two ways to use WhatsApp as a team: applying for the official API or connecting your existing number via a QR code. Which one is right for your business?
The WhatsApp Business API is designed for large-scale, template-based bulk messaging. It involves applying through an official BSP (solution partner), business verification, template approvals and per-conversation pricing. Setup can take days, and the cost rises with volume.
FlexInbox offers a different path: you connect the WhatsApp number you already use via a QR code, just like on your phone. There is no approval process or template requirement; your number stays the same, and you start using it as a team within minutes.
| Feature | Business API | FlexInbox (QR) |
|---|---|---|
| Setup time | Days (application + approval) | Minutes |
| Number | Usually a new number | Your existing number |
| Template approval | Required | Not needed |
| Cost | Per-conversation fee | Fixed subscription per line |
| Multiple agents | Yes | Yes |
| CRM logging & AI | Depends on integration | Built-in |
| Best suited for | Very high-volume bulk notifications | One-to-one conversations & support/sales |
If you send tens of thousands of automated notifications a day (OTPs, campaigns), the API makes sense. But if your goal is to talk one-to-one with customers and run support and sales, connecting your existing number via QR is much faster, cheaper and more flexible.
Combining the two is also possible. You can find how to connect WhatsApp to your CRM on our WhatsApp CRM integration page, and the prices on the pricing page.
FlexInbox is designed for one-to-one customer conversations. The key is to build genuine dialogue with your customers rather than sending bulk, unsolicited messages.
Yes, the official API requires Meta business verification and template approval processes. There are no such processes with QR connection.
Yes, you can switch to the API as your needs grow. For most businesses, QR connection is enough for a long time.
Use WhatsApp as a team without waiting for approval or changing your number.
