WhatsApp Business

Connecting the WhatsApp Business API — approved templates and the 24-hour rule, step by step.

What can you do?

Connect your business number via the WhatsApp Business API, and your customers' messages appear in SLINK as normal chats (text, images, files and read receipts). Reply and manage everything from one place.

Connection steps

1. Open the menu → Connect and choose WhatsApp Business.
2. Follow the verification for your business number (requires a number not used by regular WhatsApp).
3. Once active, customer messages start arriving in your chats.

Message templates

WhatsApp Business relies on pre-approved templates for outreach outside the reply window. Common examples:

• Order confirmation
• Shipping status update
• Appointment reminder
• Welcome message

Templates are submitted to Meta for approval before use, and SLINK helps you prepare and send them.

The 24-hour rule

When a customer messages you first, a 24-hour window opens in which you can reply freely with regular messages. After the window closes, you must use an approved template to reach them again.

SLINK handles this automatically: it replies freely inside the window and switches to templates after it — no counting on your part.
