🗨️ Build a WhatsApp API using Node & Express

Do you want to get the status of a message if that is pending, delivered or read??

If that's what you want, you can do something like this:

// Store the sent message in a variable
const sentMessage = await client.sendMessage(chatId, content);

console.log(sentMessage.ack)

sentMessage.ack will be either one of these:

• ACK_ERROR
• ACK_PENDING
• ACK_SERVER
• ACK_DEVICE
• ACK_READ
• ACK_PLAYED

For more information, you can refer the docs

Hi Eizil! Thanks for commenting and asking 😃.

So if you want to use this API with multiple numbers, the whatsapp-web.js team actually worked on the multi-device feature here and they successfully published that to production.

With that, now you can set the clientId property in the Client constructor that will load the client of your choice once they are logged in. So you can make it dynamic in your case.

Usman Sabuwala that was quick, thank you for your reply, will look into it and try it myself.

thanks again

Hi. Sorry there was a mistake in the post that I updated now. When requiring all the packages, in order to make express work, you will have to initialise the app variable which I forgot. Thank you for pointing out the mistake.

Add this line with other variables

const app = express();

Hi Usman Sabuwala ~ Thanks so much for your reply , that is working for me now ~ Thanks so much for your help ~^_^
