This code is an implementation of Baileys, as a RestFull Api service, which controls whatsapp functions.
With this one you can create multiservice chats, service bots or any other system that uses whatsapp. With this code you don't need to know javascript for nodejs , just start the server and make the language requests that you feel most comfortable with.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash
# or
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash

After finishing, restart the terminal to load the new information.

curl -fsSL https://get.docker.com -o get-docker.sh

sudo sh get-docker.sh

sudo usermod -aG docker ${USER}

nvm install 18.17.0

npm i -g pm2

npm i -g yarn

docker --version

node --version

After installing docker and docker-compose, up the container.

• compose from mongodb

In the same directory where the file is located, run the following command:

bash docker.sh

Using the database is optional.

Cloning the Repository

git clone https://github.com/code-chat-br/whatsapp-api.git

Go to the project directory and install all dependencies.

cd whatsapp-api

yarn i

Finally, run the command below to start the application:

# Under development
yarn start

# In production
yarn start:prod

# pm2
pm2 start 'yarn start:prod' --name ApiCodechat

• Route: http://localhost:8083/docs
• YAML file: swagger.yaml

You can define two authentication types for the routes in the env file. Authentications must be inserted in the request header.

1. apikey

2. jwt: A JWT is a standard for authentication and information exchange defined with a signature.

Authentications are generated at instance creation time.

Note: There is also the possibility to define a global api key, which can access and control all instances.

NOTE: This key must be inserted in the request header to create an instance.
