Help, please I was blocked by 2 WhatsApp business accounts

[supple rock]

I have a problem, I have been blocked by WhatsApp business more than 2 times when sending app.post('/send-message', async(req, res) => {
const number = req.body.phone;
const messages = req.body.message;
if (process.env.DEFAULT_MESSAGE === 'true') {
await sendNumber(client, number, req.body.message, null);
setTimeout(() => {
sendMediasnumber(client,number,req.body.img);
console. log(number);
res.json({ success: true, message: 'Successfully sent message: '+messages});
}, 5000);
} else {
res.json({ success: false, message: 'Messaging disabled' });
}
});
, from my fontend I give a delay that sends each message to each number every 6 seconds, and in the backend in node.js the second message every 5 seconds, but in the same way, whatsapp blocks my account, any suggestions to avoid this, the Client will start like this client = new Client({
authStrategy: new LocalAuth(),
puppeteer: {
executablePath: 'C:/Program Files/Google/Chrome/Application/chrome.exe',
}
});

Helping you is not easy as you think. Being blocked by Meta has different reasons and possibilities, and you need to understand the behavior behind the block.
Try to not to send spam, make sure to send messages only to people that started a conversation with you before, not send messages at the same time or with a fixed second between them.
Think about how people will receive the messages because they might denounce you to Meta as a spammer.
As you can see, there are several ways to get banned, and you need to deal with them all the time.

Thank you, because I think that for what I am doing it is better to use the WhatsApp API

if u have been blocked just send whatsapp support an email saying you dont know why you have been banned. this got me unbanned many times lmao. But then also try not to spam next time and if you are new registered number to whatsapp maybe wait some days before using it for bot usage

Thank you, it is correct, the number I am using is new, an app was being developed which allows me to send messages in a massive way that I already have stored in a DB, when I sent the 6th message I was blocked, the numbers did not start the chat, but I from the boot, I created a timeout of 10 seconds to send each message, but still I was blocked

"send messages in a massive way" this is the reason you got banned
