The user writes to you, or you send a template message. Then the conversation develops in chat.
There's a logic of conversational windows and rules. These rules help protect the user from spam.

These requirements reduce risks and disputes.

Templates, conversations, and quality: the mechanisms that impact results
APIs distinguish between service messages and conversations.
When you write proactively, you often use a template. Meta approves it to reduce abuse.
Quality is crucial. Reports and user blocks lower your rating, which can limit throughput and performance.

- relevant,
- expected,
- short,
- with a clear call to action.
As a result, you increase responses and reduce opt-outs.

The WhatsApp Business API works well where speed and traceability are needed.
Here are some typical scenarios.
- Order confirmations and shipping updates.
- Appointment reminders and no-show reduction.
- Post-sales support with tickets.
- Cart recovery and hot lead reactivation.
- Security notifications and OTPs (if allowed).
