Z-API - Wings for your imagination!

Z-API was developed by developers for developers, so we value simplicity and objectivity in everything we do — no fluff, just results. Let’s go!

But what is Z-API?

You probably already know, but let’s reaffirm! Z-API is a RESTful service that provides an API allowing you to interact with your WhatsApp through a simple and intuitive interface, along with webhooks to notify you about interactions with your number.
ImportantZ-API reaffirms that it is not intended for SPAM, sending unwanted messages, or any action that violates WhatsApp’s terms of service.Use the API wisely by creating features that generate value for your customers and WhatsApp users.

Who can use Z-API?

We have no restrictions on usage, but generally there are 2 distinct audiences who use our services:
  • Developers with knowledge of RESTful APIs. If you’re not one, but know someone with these skills, that works too :)
  • Users of third-party solutions that allow integration with Z-API

What can I do with it?

Simply put, everything you do with WhatsApp Web you can do using our service. Just scan Z-API’s QR code and start using our service!

Technically, how does the sending flow work?

Here are the steps for sending a simple text message:
  1. You send a message to Z-API via API;
  2. Z-API adds it to a queue and returns the message ID;
  3. Your instance processes the queue, sending it to WhatsApp;
  4. Your delivery webhook is called when the message is processed, notifying you that it was sent or that there was a failure.
  5. As soon as the recipient receives the message, the message-status webhook is called with RECEIVED.
  6. Finally, when the recipient reads the message, messages-status is called with READ.

Limits

We start here because people often ask about sending limits with Z-API. We have NO LIMIT on the number of messages sent! But it’s important to understand that you are using a WhatsApp Web session, so usage patterns need to be compatible. We also always recommend carefully reading WhatsApp’s policies at https://www.whatsapp.com/legal.
WE DO NOT STORE MESSAGES!All messages sent to our API will be forwarded to a message queue and deleted after sending.
RememberFacebook has different behaviors for each version of WhatsApp. Our API provides methods compatible with the WEB version.
