Unoapi Cloud

An implementation of Baileys(https://github.com/WhiskeySockets/Baileys) as RESTful API service with multi device support with a Whatsapp Cloud API format https://developers.facebook.com/docs/whatsapp/cloud-api.

The media files are saved in file system at folder data with the session or in s3 or compatible and redis.

Read qrcode or config

Go to http://localhost:9876/session/XXX, when XXX is your phone number, by example http://localhost:9876/session/5549988290955. When disconnect whatsapp number this show the qrcode, read to connect, unoapi response with auth token, save him. When already connect, they show the number config saved in redis, you cloud update, put the auth token and save.

The qrcode is send to configured webhook to, you can read in chatwoot inbox, in created chat with de same number of connection.

Qrcode with websocket

Use the endpoint /ws and listen event broadcast, the object with type qrcode has a content attribute with de base64 url of qrcode

import { io } from 'socket.io-client';
const socket = io('http://localhost:9876/ws', { path: '/ws' });
socket.on('broadcast', data => {
  console.log('broadcast', data);
});

Send a Message

The payload is based on https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks/components#messages-object

To send a message

curl -i -X POST \
http://localhost:9876/v15.0/5549988290955/messages \
-H 'Content-Type: application/json' \
-H 'Authorization: 1' \
-d '{
  "messaging_product": "whatsapp",
  "to": "5549988290955",
  "type": "text",
  "text": {
    "body": "hello"
  } 
}'

To send a message to group

curl -i -X POST \
http://localhost:9876/v15.0/5549988290955/messages \
-H 'Content-Type: application/json' \
-d '{
  "messaging_product": "whatsapp",
  "to": "120363040468224422@g.us",
  "type": "text",
  "text": {
    "body": "hello"
  }
}'

Media

To test media

curl -i -X GET \
http://localhost:9876/v15.0/5549988290955/3EB005A626251D50D4E4 \
-H 'Content-Type: application/json'

This return de url and request this url like

curl -i -X GET \
http://locahost:9876/download/v13/5549988290955/5549988290955@s.whatsapp.net/48e6bcd09a9111eda528c117789f8b62.png \

Webhook Events

Webhook Events like this https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks/payload-examples

Message status update on this https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks/payload-examples#message-status-updates

To turn possible work with group, we add three fields(group_id, group_subject and group_picture) in message beside cloud api format if IGNORE_GROUP_MESSAGES is false. Unoapi put field picture in profile.

{
  "object": "whatsapp_business_account",
  "entry": [{
      "id": "WHATSAPP_BUSINESS_ACCOUNT_ID",
      "changes": [{
          "value": {

Templates

UnoAPI's default definition has 4 templates: hello, unoapi-bulk-report, unoapi-webhook and unoapi-config. UnoAPI can be configured to only present the hello template as default, check the ONLY_HELLO_TEMPLATE variable to obtain this behavior

The templates for each Session (PHONE_NUMBER) can be be customized, saving in ${BASE_STORE}/${PHONE_NUMBER}/templates.json , or when use redis with key unoapi-template:${PHONE_NUMBER}. The json format is:

[
  {
    "id": 1,
    "name": "hello",
    "status": "APPROVED",
    "category": "UTILITY",
    "components": [
      {
        "text": "{{hello}}",
        "type": "BODY",
        "parameters": [
          {
            "type": "text",
            "text": "hello",
          },
        ],
      },
    ],
  }
]

Save templates with http

To edit (by id) or add a template with http send a post with the template in body to http://localhost:9876/v15.0/:phone/templates, change :phone by your phone session number and put content of env UNOAPI_AUTH_TOKEN in Authorization header:

curl -i -X POST \
http://localhost:9876/v17.0/5549988290955/templates \
-H 'Content-Type: application/json' \
-H 'Authorization: 1' \
-d '{"id":1,"name":"hello","status":"APPROVED","category":"UTILITY","components":[{"text":"{{hello}}","type":"BODY","parameters":[{"type":"text","text":"hello"}]}]}'

PS: After update JSON, restart de docker container or service

Caution with whatsapp web connection

More then 14 days without open app in smartphone, the connection with whatsapp web is invalidated and need to read a new qrcode.

Future providers

Current lib is baileys, to other libraries implement subscribe:

• incoming and convert whatsapp cloud api format to lib format
• disconnect to remove conection
• reload do close socket and reopen

to send messages:

• write in rabbitmq queue outgoing in format
