WhatsApp Business API vs QR connection — which fits

The two routes, briefly

A QR connection works like WhatsApp Web: you scan a code once from the phone and the system is linked to the existing number. There is no approval process, no per-message fee, and setup takes minutes.

The WhatsApp Business API is Meta's official route: you register through an approved provider, pass business verification, and receive a dedicated channel. Setup takes days to weeks, and every outbound message is priced.

What actually differs

The differences that matter in practice to a small business:

• Cost. QR has no per-message fee. The API prices per conversation or per message, which adds up substantially in a business sending a reminder for every appointment.
• Setup time. QR — minutes. API — business verification with Meta, usually days.
• Bulk outbound. This is the API's genuine strength: approved templates and sending to thousands. On QR, bulk sending is precisely what puts a number at risk.
• Stability. The API is an official channel with a commitment behind it. QR depends on a link that can drop and require rescanning.

What actually risks a number

Many owners have heard that "a bot on WhatsApp risks your number" and stopped there. The precision matters: what risks a number is behaviour that looks like spam — unsolicited outbound to numbers that never contacted you, the same message to dozens of people at once, and a high rate of blocks and reports from recipients.

Replying inside conversations customers opened is the opposite: it is the ordinary pattern of a business answering its customers. The distinction is not between "a bot" and "a human" but between answering an enquiry and unsolicited broadcast.

Which suits whom

For a typical appointment business — a salon, a clinic, a garage, a studio — where most communication is answering enquiries and reminding existing customers, a QR connection is a fit and is substantially cheaper.

The API makes sense when there is large-scale outbound volume, when a formal availability commitment is required, or when the business is large enough that per-message cost is negligible against the value of stability. It is a decision of scale, not of quality.

Questions worth asking any vendor

Whichever route you choose, three questions quickly reveal what you are dealing with: does my existing number stay, or do I get a new one my customers do not recognise? Is conversation history preserved or does it start from zero? And if I leave — what happens to the number and the data?

A vague answer to any of the three usually signals that the connection is less stable, or less yours, than it sounded. Especially the first: a new number means losing every customer who already saved you in their contacts.

What iGenTor does

We connect by QR to the existing business number. That choice is deliberate: it keeps setup to minutes, keeps reminders free of per-message cost, and keeps the customer messaging the same number they already know — which also preserves the conversation history.

Alongside that we deliberately limit large-scale outbound and favour replies and reminders to customers already in contact with you, because that is both what is safe for the number and what actually produces bookings.
