What is the difference between the official WhatsApp API and connecting by QR code?
Short answer
Meta's official API is the contracted path: the company is verified and starting a conversation is paid. The QR code keeps the number on the phone and costs less, but sits outside Meta's terms and can be blocked.
The table to decide
| Official API | Phone app | QR code | |
|---|---|---|---|
| Time to connect | One to two days | Hours | Minutes |
| Verification | Required | No | No |
| Within Meta's terms | Yes | No | No |
| Risk of being blocked | Low | High | It exists |

How to choose?
- Will you start conversations, with reminders or billing? Official API.
- Only answering, and want to keep your usual number? QR code, accepting that you'll reconnect now and then.
- A bot on the phone app breaks on the first update.
