Wazapin allows you to send pre-approved message templates to customers. Message templates are required when you want to initiate a new conversation or message a customer outside the active 24-hour customer service window.
When to use templates
Use templates for business-initiated updates, alerts, and transactional messages:
| Category | Typical use cases | Examples |
|---|
| Authentication | One-Time Passwords (OTPs) and account verification. | "Your verification code is 482910." |
| Utility | Post-purchase notifications, shipping alerts, billing reminders, and updates. | "Your order #1032 has been shipped! Track it here: {{1}}." |
| Marketing | Promotional offers, newsletters, and welcome messages. | "Get 20% off our summer collection. Click to claim: {{1}}" |
Creation and approval flow
Before you can send a template, it must be created and approved by Meta (for official channels).
- Create: Design your template body, define variables (e.g.
{{1}}, {{2}}), and add optional headers (text or media) or interactive buttons.
- Review: Wazapin automatically submits your template to Meta. Review times typically take between a few minutes and a few hours.
- Sync: Once approved, the template status updates to
approved. You can also synchronize templates programmatically via POST /v1/templates/sync.
Unofficial channels do not require Meta review. Wazapin will simulate template styling directly, but maintaining proper template design is recommended if you plan to upgrade to official channels later.
Variable substitution
Templates support dynamic components using parameter placeholders (like {{1}}). When sending a template via the API, you must pass the exact list of variables corresponding to the placeholders in the order they were defined.
For example, a utility template body:
Hi {{1}}, your order #{{2}} is ready.
Requires passing two text parameters:
{{1}} -> "Ayu"{{2}} -> "29420"
