Whatsapp API Tutorial

Hi, this is the implementation example of whatsapp-web.js

Watch the tutorials:

Important thing!

As because Whatsapp regularly makes an update, so we needs to always use the latest version of whatsapp-web.js. Some errors may occurs with the old versions, so please try to update the library version before creating an issue.

How to use?

Clone or download this repo
Enter to the project directory
Run npm install
Run npm run start:dev
Open browser and go to address http://localhost:8000
Scan the QR Code
Enjoy!

Send message to group

You can send the message to any group by using chatID or group name, chatID will used if you specify the id field in the form, so if you want to send by name, only use name.

Paramaters:

id (optional if name given): the chat ID
name (optional): group name
message: the message

Here the endpoint: /send-group-message

Here the way to get the groups info (including ID & name):

Send a message to the API number !groups
The API will replying with the groups info
Use the ID to send a message

Downloading media

I add an example to downloading the message media if exists. Please check it in on message event!

We use mime-types package to get the file extension by it's mimetype, so we can download all of the type of media message.

And we decided (for this example) to use time as the filename, because the media filename is not certain exists.
