Meta defines how businesses use WhatsApp. This page explains the concepts you need before you send WhatsApp messages through the Wavix platform.

WhatsApp Business Account

A WhatsApp Business Account (WABA) represents your business on WhatsApp. It belongs to your business portfolio in Meta Business Suite, and it holds your senders and message templates. Meta verifies your business before it lets you message customers at scale. Keep your business details in Meta Business Suite accurate and up to date — they affect approval and your messaging limits.

Senders

A sender is a phone number registered to your WABA. Each sender has:
  • Display name: The business name customers see in WhatsApp. Meta reviews the display name, and it must relate to your business.
  • Status: Whether the sender can send messages. For example, a sender can be connected, pending, flagged, or restricted.
  • Quality rating: How customers have responded to your recent messages.
  • Messaging limit: How many customers you can start conversations with in a rolling 24-hour period.
A phone number registered as a WhatsApp sender can’t be used in the WhatsApp or WhatsApp Business app at the same time.

Message templates

A message template is a message format that Meta approves before you can use it. You must use an approved template to start a conversation with a customer. Each template has a name, a language, and a category. It can include placeholders for content that changes per message, such as a customer name or an order number. Templates can also include a header with text or media, a footer, and buttons.

Template categories

Meta can change the category of a template during review if the content doesn’t match the category you chose.

Template review

Meta reviews every template before you can use it. Most templates are reviewed within minutes. A template that needs manual review can take up to 48 hours. After review, a template is either approved or rejected. Meta can also pause or disable an approved template later if it receives negative customer feedback.

Customer service window

When a customer sends you a message, a 24-hour customer service window opens. Each new message from the customer restarts the window.
  • Inside the window, businesses can reply with free-form messages.
  • Outside the window, you can only reach the customer with an approved template.

Opt-in

Meta requires your customers to agree to receive WhatsApp messages from your business before you message them. Collect opt-in through your own channels, such as your website, app, or checkout flow. State clearly that the customer will receive messages on WhatsApp and from which business. Respect opt-out requests immediately. Messages that customers don’t expect lower your quality rating.

Quality rating

Meta assigns a quality rating based on how customers respond to your messages over recent days. Blocks, reports, and negative feedback lower the rating. To keep a high rating, send relevant messages only to customers who opted in, and don’t send messages too often.

Messaging limits

Messaging limits control how many unique customers you can start conversations with in a rolling 24-hour period. Replies inside the customer service window don’t count toward the limit. New businesses start with a limit of 250 customers. Meta raises the limit to 2,000, 10,000, 100,000, and then unlimited, as you send more high-quality messages.
