Template messages must be submitted for Facebook's approval before they are available to use. It is Facebook that reviews each template to avoid spam and to check that each message complies with their WhatsApp API guidelines.

Here is a YouTube video about how to apply for the template message, you can watch it here:

When to use templates for WhatsApp messaging?

A template message needs to be sent whenever it is outside of a Customer Service Window, which means, whenever it has been more than 24 hours since the customer sent their last message to that business phone number.

You regularly use the message template to send notifications.

Templates use placeholder values that can be replaced with dynamic content inside double curly braces when the message is sent. Think of template messages as a conversation starter in a two-way conversation.

For more information about WhatsApp Template Messaging, review the Official Facebook Documentation for the WhatsApp Business API

Best practice to get your template message approved

Here are some tips to get your templates through the review process:

Clarity: be specific and clear. The reviewers may not know a customer’s business and need more clarity. Avoid promotion: upselling, cold-call messaging, sending a poll to collect data, and including certain phrases that sound promotional are all considered promotional.

Spelling: check for spelling and grammatical errors and use appropriate formatting (e.g., double curly brackets for parameters).

Name: make your message template name clear. Instead of using a name like template_014, use bus_ticket_details. Remember that someone from Facebook will be reviewing your templates. Providing more clarity gives reviewers context around how the template will be used.

Create context: if you need to write a message template to re-open the 24-hour window, we would suggest starting with some mention of the previous conversation thread.

Choose an appropriate category: don’t forget to use the correct message template type. Choosing the correct one will increase the chances of getting your templates approved and will provide more information to WhatsApp during the approval process.

The categories you can choose are listed below.

Header (optional): you can add a title or choose which type of media you'll use for this header. Image, PDF and Video are supported.
