Quick start

Requirements

Only thing that you must have - installed docker. Please follow the original instruction how to install docker ->.

When you are ready - come back and follows the below steps to send the first text message to WhatsApp via HTTP API!

{{< details "Why Docker?" >}} Docker makes it easy to ship all-in-one solution with the runtime and dependencies. You don't have to worry about language-specific libraries or chrome installation.

Also Docker makes installation and update processes so simple, just one command! {{< /details >}}

Send your first message

Let's go over steps that allow you to send your first text message via WhatsApp HTTP API!

1. Download image

Assuming you have installed Docker, let's download the image.

For Core version the command is

docker pull devlikeapro/whatsapp-http-api

For Plus version, we use login to get the image before:

docker login -u devlikeapro -p {KEY}
docker pull devlikeapro/whatsapp-http-api-plus
docker logout

Read more about how to get PASSWORD for [Plus Version →]({{< relref "plus-version" >}})

2. Run WhatsApp HTTP API

Run WhatsApp HTTP API:

docker run -it --rm -p 3000:3000/tcp --name whatsapp-http-api devlikeapro/whatsapp-http-api

# It prints logs and the last line must be
# WhatsApp HTTP API is running on: http://[::1]:3000

Open the link in your browser http://localhost:3000/ and you'll see API documentation (Swagger).

3. Start a new session

To start a new session you should have your mobile phone with installed WhatsApp application close to you.

Please go and read how what we'll need to a bit later: How to log in - the instruction on WhatsApp site

When your ready - find POST /api/session/start, click on Try it out, then Execute a bit below.

The example payload:

{
  "name": "default"
}

By using the request with name values you can start multiple session (WhatsApp accounts) inside the single docker container in Plus version and only one account in Core version.

Read more about [multiple sessions →]({{< relref "/docs/how-to/sessions" >}})

4. Get and scan QR

Find GET /api/screenshot and execute it, it shows you QR code.

Scan the QR with your cell phone's WhatsApp app.

5. Get the screenshot

Execute GET /api/screenshot after a few seconds after scanning the QR - it'll show you the screenshot of you Whatsapp instance. If you can get the actual screenshot - then you're ready to start sending messages!

6. Send a text message

Let's send a text message - find POST /api/sendText in swagger and change chatId this way: use a phone international phone number without + symbol and add @c.us at the end.

For phone number 12132132131 the chatId is [email protected].

The example payload:

{
  "chatId": "[email protected]",
  "text": "Hi there!",
  "session": "default"
}

Also, you can use curl and send POST request like this:

# Phone without +
export PHONE=12132132130
curl -d "{\"chatId\": \"${PHONE}@c.us\", \"text\": \"Hello from WhatsApp HTTP API\" }" -H "Content-Type: application/json" -X POST http://localhost:3000/api/sendText
