Usage

• Start the container with: docker-compose up app
• Check the console to scan the QR code
• Scan the code via whatsapp
• Send messages via curl or postman

Start a new session

As the project supports for multiple sessions, you need to start a session via GET /start/:key

curl http://localhost:3008/start/my-session1 # session to send messages using the first phone (account)
curl http://localhost:3008/start/my-session2 # session to send messages using a second phone (account)

Send messages

Send messages by calling POST /message/:key

• Send text messages

curl -v \
  -H "Accept: application/json" \
  -H "Content-type: application/json" \
  -X POST \
  -d '{"phone": "5917090909@c.us", "content": "test message"}' \
  http://localhost:3008/message/my-session1

• Send image messages (data can be a url or a base64 string)

  curl -v \
  -H "Accept: application/json" \
  -H "Content-type: application/json" \
  -X POST \
  -d '{"phone": "5917090909@c.us", "content": "same img descr here", "media": { "data": "https://www.shutterstock.com/image-vector/sample-red-square-grunge-stamp-260nw-338250266.jpg", "mimetype": "image/png", "filename": "image.png" }}' \
  http://localhost:3008/message/my-session1
