What it is for
What businesses send through WhatsApp
Most customers of this API are internet providers, and the use is almost always the same: take away from your support staff whatever the system can send on its own.
Invoice and payment code
Your ERP generates the invoice and the API sends the PDF and the copy-and-paste payment code to the customer's WhatsApp on the right day. Fewer late payments, fewer calls asking for a second copy.
Due date reminders
A notice before the due date, on the due date and before service suspension, with the amount and a payment link. Billing rules that systems like MK-Auth, IXC and Hubsoft already know how to build.
Network notices
Scheduled maintenance, an outage in one region, service restored: one message to every affected customer, triggered from Zabbix, The Dude or your ERP.
Service orders
Appointment confirmation, technician on the way and job completed, sent by your system when the order status changes.
Sales and campaigns
Promotions, plan upgrades and referral offers sent to your customer base, with image or video, from the number they already know.
Any system with an API
If your software can make an HTTP request, it can send through WhatsApp: WHMCS, Zabbix, PlaySMS, Gammu, custom scripts, n8n.
Integrations
Works with the system you already use
The API follows the Evolution API standard, which the main ISP and management systems already recognize on their notification settings screen. Usually you only enter the API address, the instance name and the key.

Your system is not on the list? If it sends webhooks or HTTP requests, it integrates the same way. Talk to us and we will check it with you.
How it works
From order to first message
1. Order and get access
After payment, you receive the API address, the instance name and the key by email and WhatsApp, along with the panel to connect your number.
2. Scan the QR Code
Open WhatsApp on the number that will send messages (a regular SIM or WhatsApp Business), scan the QR Code in the panel and you are done: the number is connected and you stay in control.
3. Paste the details into your system
On your ERP's notification screen, enter the address, instance and key. Send a test. From then on, invoices, reminders and notices go out on their own.
Ready-made API or Evolution on your VPS?
Two ways to run a WhatsApp API at Mega
Ready-made WhatsApp API (this page)
The instance runs on a Mega server in Brazil. You do not manage any server: you connect the number and integrate. Best for businesses and providers that only want to send messages.
Evolution API on your VPS
You order a Cloud VPS with Evolution API installed and manage the instance yourself: multiple numbers, webhooks, and integrations with Chatwoot, Typebot and n8n on the same server. Best for teams building on top of the API.
Frequently asked questions
Before you order the WhatsApp API
What is a WhatsApp API?
It is a service that lets your system send WhatsApp messages through HTTP calls, with nobody typing on a phone. Your ERP, WHMCS or a script calls the API with the phone number and the content, and the message goes out from the connected number.
Do I need a new number or can I use mine?
You use your own. Any number with WhatsApp (a regular SIM or WhatsApp Business) is connected by QR Code, like WhatsApp Web. The number keeps working normally on your phone.
Is there a message limit?
There is no monthly limit and no per-message fee. Sending is capped at 30 messages per minute per instance, to protect the number and keep delivery stable.
Can I send PDF invoices and payment codes?
Yes. The API sends text, PDFs (such as a boleto), images and videos. A Pix copy-and-paste code goes as text and the boleto as a document, the same way MK-Auth, IXC, Hubsoft and MK Solutions already build them.
Which systems are compatible?
MK-Auth, IXC Provedor, Hubsoft, MK Solutions, SGP, Controllr, WHMCS, Mk Full, RbFull, Ispfy, Gesprov, The Dude, Zabbix, PlaySMS and Gammu, plus any system that makes HTTP requests or sends webhooks.
Can WhatsApp block my number?
WhatsApp can restrict numbers that send mass messages to people who are not customers. When you use the API to notify your own customers with useful content (invoices, service orders, maintenance) and stay within 30 messages per minute, the usage is the same as an agent on WhatsApp Web. Spam to purchased lists is not allowed.
Does it work with the official Meta API?
This API uses your own number connected by QR Code, with no per-conversation fee. If you need the official API (WhatsApp Business Platform), Evolution API installed on your VPS also supports that mode.
Can I connect more than one number?
Each instance serves one number. For two or more numbers, order one instance for each; billing is per instance.
How long until it is ready?
The instance is created after payment is confirmed and the access details arrive by email and WhatsApp. Connecting the number takes about a minute.
