Keep your app in the loop.
Receive events via webhooks, configure filters and track deliveries and retry attempts.

CLEAR INTEGRATION, FROM THE FIRST STEP
Your stack.
A straightforward integration.
One HTTP request connects what your product does to the conversation your customer receives. Start with an example and explore the API at your own pace.
- 01
Create your instance
With an enabled account, create an instance through the dashboard or API.
- 02
Connect WhatsApp
Scan the QR code or use the pairing code on your phone.
- 03
Send. Receive. Build.
Use the instance token to send messages and configure your webhook to receive events.
Your first message
curl --request POST \
'https://muapi.com.br/api/INSTANCE/message/send-text' \
--header 'api-key: INSTANCE_TOKEN' \
--header 'Content-Type: application/json' \
--data '{
"chatId": "5511999999999",
"text": "Hello! Your order has been confirmed."
}'Authentication via the api-key header
A real request example. Replace the instance and token with your credentials. This page does not send messages.

Is support provided by real people?
Yes. Muapi provides fast, human support from a team that understands WhatsApp integrations and operations. Support channels and hours follow the terms of your plan.
When were the platform figures collected?
The figures shown on this page were collected on September 15, 2026.
What are the Black Friday terms?
Request your Black Friday proposal on WhatsApp. Pricing, limits and availability depend on the plan and are provided before you sign up.
Can I build my integration with AI assistance?
Yes. Use our documentation, OpenAPI and examples as context for your coding assistant. You remain responsible for reviewing the code, configuring credentials in your backend and testing the integration. This does not automatically connect the assistant to your Muapi account.
Is Muapi the official Meta API?
No. Muapi uses Whatsmeow to connect WhatsApp through device pairing. It is not Meta’s WhatsApp Cloud API. Connectivity depends on WhatsApp and may be restricted; there is no guarantee against account blocks.
How do I get started?
Access documentation and examples without logging in. To activate your operation, sign up for Muapi and use the dashboard to create your instance, connect WhatsApp and get your access token.
Does it work with n8n, Make and my CRM?
You can integrate tools that make HTTP requests and receive webhooks. In n8n and Make, use the generic HTTP modules. Muapi does not require you to change your stack.
Can I manage numbers for multiple clients?
Yes. The platform lets you manage multiple instances through the dashboard or API. Every session has its own environment and access token. Available quantities depend on your account configuration.
How do I receive messages and monitor connectivity?
Configure a webhook URL on your instance to receive events. You can select events, apply filters and check delivery status and failures. The documentation includes fields and examples.
