Whatsapp-web.js: Send Message dont give a return

[LucasDR]

When i use client.SenMessage i cant know if its works or not because i never get a response.

router.post('/api/v1/send',(req,response) => {

var from  = req.body.from;
var mensagem = req.body.mensagem;
console.log(client.sendMessage(from,mensagem));

});

What i doing wrong ???

Thisis my code "client.sendMessage(from,mensagem)" i want send a message to a from number its working, the problemn on return of this "client.sendMessage(from,mensagem)" i need when i call this know if the message was send or not understand ?

[guicuton]

You can use the event message_create → event:message_create

client.on('message_create', async (msg) => {
    console.log('NEW MESSAGE', msg);
})

This will be fired when you send or receive a message.
This could be used together of message_ack event to get the status of message sent

client.on('message_ack', async (msg, ack) => {
    console.log('MESSAGE SENT', msg, ack);
})

This package will try send the message even to a WA's invalid number. So, you'll need to verify before of send a message. For this i recommend you check the method isRegisteredUser()

To remember
sendMessage()method return a Promise containing the message object

guicuton gave you some great tips 👍

Something to keep in mind is sendMessage() returns a Promise that resolves when the message is queued up to be sent. In your example, since you are logging the return value directly, you would be logging a promise. If you want to log the created message object, you should first await the promise if using async-await syntax or .then() otherwise. (console.log(await client.sendMessage(from,mensagem));)

If you want to confirm that the message was sent, this is done through the message_ack event, like the previous post specifies.

Hi everyone, i can use the code like this

client.on('message_create', async (msg) => {
// save msg in database
})
client.on('message_ack', async (msg, ack) => {
//when i receive this i check my data base and change de message status ?
})

[guicuton]

Yes Lucas!
with message_create you'll receive object with message values (sent and received) and with message_ack you'll receive new ack status from message sent

ACK STATUS

• ACK_ERROR: -1
• ACK_PENDING: 0
• ACK_SERVER: 1
• ACK_DEVICE: 2
• ACK_READ: 3
• ACK_PLAYED: 4

[LucasDR]

Yes it i understand, what i dont is how can is use this two functions together ???

[LucasDR]

Whats i dont understand is when or how it is called

client.on('message_ack', async (msg, ack) => {
//when i receive this i check my data base and change de message status ?
})

[LucasDR]

Please somebody save meee (smallville theme kkkk), i dont understand how can i use this two "events functions" togheter ...

[guicuton]

Each event has it's own results...
For each of them you should take your "actions"

client.on('message_create', async (msg) => {
//here goes all your code to save messages received and sent
})
client.on('message_ack', async (msg, ack) => {
//here goes all your code to save/update the message sent by paired client
})

@LucasDR you're going to a "offtopic" theme instead a real issue on the lib.
Join the discord server and look for this kind of help there since that your problem is "how to do" instead a "real bug/problem" on the lib
