Not every tool that says "WhatsApp automation" connects to WhatsApp the same way. The difference between official and unofficial access matters more than most of the feature list, because it affects whether your business number stays usable at all.
Unofficial tools typically automate a real WhatsApp account by scraping or driving a logged-in session, which is the same thing as running a bot through your personal WhatsApp Web login. This is against WhatsApp's Terms of Service, and Meta actively detects and bans numbers used this way, often without warning.
The official WhatsApp Business API (Meta's Cloud API) is a real integration Meta provides for businesses, accessed through an approved Business Solution Provider. Message templates go through Meta's approval process, and the number operates within WhatsApp's actual rules rather than around them.
A number on an unofficial tool can be banned at any time, taking every saved contact and conversation history with it. A number on the official API doesn't carry that risk. It's the same infrastructure WhatsApp itself expects businesses to use at scale.
Repeat Grow is built entirely on the official WhatsApp Business API. There is no unofficial or session-based mode. We handle the Business verification and number registration as part of setup, so you get the shared inbox, pipelines, and automation without the ban risk.
