One credential for all clients
Each client of your product connects its own number. You tell connections apart with the identifier you already use in your database.
OFFICIAL WHATSAPP API
The official WhatsApp API for your software and your business
Software companies integrate WhatsApp into their own products with a single API, and each client company can connect its own WhatsApp Business number through Meta's official screen. Everything is built on Meta's official Cloud API.
The platform is operated by Totta Consultoria e Sistemas LTDA under the Inteligencialy brand.
WHO IT IS FOR
Two ways to use the same platform
For software companies
You run a product, such as scheduling, ERP, CRM, delivery or clinic management, and want to offer official WhatsApp to your clients inside it.

See how it worksFOR SOFTWARE COMPANIES
One integration, all your clients on WhatsApp
Instead of each of your clients hiring and setting up WhatsApp on their own, your product integrates our API once and offers the connection inside the product.
The number stays on the phone
With Coexistence, the client connects the WhatsApp Business account it already uses and keeps replying from the phone app, while your product talks through the same number.
Phone history and contacts
With Coexistence, the API asks Meta for up to six months of conversations and the phone's contact list, so your product does not start from scratch.
Templates ready in every account
The message templates your product uses are created automatically in each client's account on connection, and go to Meta's review without anyone opening Meta's dashboard.
Cost and duplicate control
You declare the billing category you accept for each template, and the idempotency key prevents the same message from being sent twice.
Conversations and the 24-hour window
Your product reads conversations and messages, replies inside the 24-hour window and can queue a reply until the contact writes again.
How the integration works
- 01
Your product starts the connection
Your backend asks the API to start a connection for a client and receives the address of Meta's screen.
- 02
The client authorizes on Meta
The client completes Meta's official Embedded Signup and returns to your product.
- 03
The connection goes live
Your backend confirms the connection, and the API turns on message delivery and creates your product's templates.
- 04
Your product talks
From then on, your product reads and sends messages through the API, from the client's own number.
FOR BUSINESSES THAT SERVE CUSTOMERS ON WHATSAPP
A connection controlled by the company itself
The solution was developed so businesses can use their own WhatsApp Business channel to serve their own customers.
Official infrastructure
The platform is built on Meta's official WhatsApp Business Platform (Cloud API).
The client company's number
Each company connects its own WhatsApp Business number and keeps that number as the channel for conversations with its customers.
Authorization by the company
The client company authorizes the connection itself through Meta's official Embedded Signup within the system we provide.
HOW IT WORKS
From authorization to customer service
The flow keeps the client company in control of the number and the conversations used in its operation.
- 01
The company connects its own number
The client company completes Meta's official Embedded Signup within the system and authorizes the connection of its own WhatsApp Business account and number.
- 02
Messages arrive in the company's environment
Once connected, the company receives on the platform the messages its customers send to the authorized number.
- 03
The team replies from the same number
The company replies there, manually or with automation support, always using its own number to serve its own customers.
DATA AND PRIVACY
Data limited to delivering customer service
The platform uses only the data required to deliver each client company's messaging service.
Data used and its purpose
The exchanged messages and the client company's WhatsApp account and phone number identifiers are used exclusively to receive, organize, and deliver that company's customer service.
Conversations separated by company
Each client company can see only its own conversations. This data is not used for any other purpose.
USE CASES
Day-to-day business communications
The platform supports practical communication flows between each company and its own customers.
Appointment confirmation
The company can confirm dates and times with a customer through the WhatsApp Business number it connected.
Customer service
The team can receive questions and reply to requests in a conversation associated with the company's own number.
Reminders and notices
Appointment reminders, schedule change notices and operational announcements sent with approved templates.
Notifications from your product
A product can notify end customers about events, such as an order being ready or a payment confirmed, using utility templates.
PRICING
Pricing on request
The platform price depends on the number of connections and the type of use. Talk to us to get a proposal.
Request a proposalWhat Meta charges
Templates are charged by Meta directly to the WhatsApp account of each client company, according to Meta's official rates.
Replies inside the window
Replying to a contact inside the 24-hour window opened by their message does not use a template.
Payment method on Meta
To send templates, the client company needs a payment method registered in its Meta account. The API returns a specific error when it is missing.
FREQUENTLY ASKED QUESTIONS
Questions about the WhatsApp API
Is it the official WhatsApp API?
Yes. The platform is built on the WhatsApp Business Platform, using Meta's official Cloud API. It is not WhatsApp Web automation.
Does the number keep working on the phone?
With Coexistence, yes: the number stays in the WhatsApp Business phone app and also on the API. Meta turns off some features on that number, such as disappearing messages, view once, live location and broadcast lists. With the standard connection, the number works only through the API.
Can I offer it to many clients of my product?
Yes. The API was designed for that: one integration of your product serves all your clients, and each one connects its own number. Each client sees only its own conversations.
Do I need Meta's approval?
Your client authorizes the connection on Meta's official screen, inside your product, and the WhatsApp account remains theirs. Templates go through Meta's review before the first send.
How do I start the integration?
Read the public documentation and talk to us to get an access credential. The integration is done by your backend, server to server.
How much does it cost?
Platform pricing is on request. Templates are charged by Meta to each client company's account, according to Meta's official rates.
