WhatsApp Business API or Connecting via QR?
There are two ways to use WhatsApp as a team: apply for the official API, or connect your existing number with a QR code. Which one is right for your business?
Two approaches, two different costs
The WhatsApp Business API is designed for large-scale, template-based bulk messaging. It involves an application through an official BSP (solution partner), business verification, template approvals, and per-conversation billing. Setup can take days and the cost rises with volume.
FlexInbox offers a different path: you connect the WhatsApp number you already use with 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.
API vs. connecting via QR
| Feature | Business API | FlexInbox (QR) |
|---|---|---|
| Setup time | Days (application + approval) | Minutes |
| Number | Usually a new number | Your existing number |
| Template approval | Required | Not required |
| Cost | Charged per conversation | Fixed subscription per line |
| Multiple agents | Yes | Yes |
| CRM records & AI | Depends on integration | Built in |
| Best suited for | Very high-volume bulk notifications | One-to-one conversations & support/sales |
Which one should you choose?
If you send tens of thousands of automated notifications a day (OTPs, campaigns), the API makes sense. But if your goal is to have one-to-one conversations 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.
Frequently asked questions
Does connecting via QR comply with WhatsApp's rules?▾
FlexInbox is designed for one-to-one customer conversations. Rather than sending bulk unsolicited messages, the key is to have genuine dialogue with your customers.
Is business verification required for the API?▾
Yes, the official API requires Meta business verification and template approval processes. With QR connection, these processes do not apply.
Can I move my number to the API later?▾
Yes, when your needs grow, switching to the API is possible. For most businesses, QR connection is sufficient for a long time.
