@@manfraio Thank you so much man looking forward to it !! 🔥🔥🔥

Thank you for the comment. You can create a template message with a variable that is gonna be the verification code. Just like on the video, instead of sending the user name on the variable , you send the code. Does that make sense?

@@manfraio Yes! Awesome! This way I don't need a Twillio in order to send just verification codes;) Thank you!

@@manfraio Other question, adding my own phone number to sending messages through Whatsapp, can I use the same number on my phone?

The WhatsApp Business API requires you to register a dedicated WhatsApp Business number that is separate from your personal WhatsApp number.

You mean the test number that whatsapp generated for you to use to send messages or the phone number you add, to send to that number?

​@manfraio All of them please 😢

Use the upload function to upload the pdf file to whatsapp server: async function uploadFile(filePath) { const data = new FormData() data.append('messaging_product', 'whatsapp') data.append('file', fs.createReadStream(filePath) data.append('type', 'application/pdf') const response = await axios({ url: 'graph.facebook.com/v20.0/phone_number_id/media', method: 'post', headers: { 'Authorization': `Bearer ${process.env.WHATSAPP_TOKEN}` }, data: data }) return response.data.id } Then call the uploadFile function and send a message along with the file: async function sendPDFFile() { const pdfFileId = await uploadFile(filePath) const response = await axios({ url: 'graph.facebook.com/v20.0/phone_number_id/messages', method: 'post', headers: { 'Authorization': `Bearer ${process.env.WHATSAPP_TOKEN}`, 'Content-Type': 'application/json' }, data: JSON.stringify({ messaging_product: 'whatsapp', to: 'phone_number', type: 'document', document: { id: pdfFileId, caption: 'This is message', filename: 'any_filename' } }) }) console.log(response.data) }

Yes. You would need to create a webhook on your server to listen for incoming messages, and configure this webhook on your whatsapp business platform: // Webhook to receive messages from WhatsApp app.post('/webhook', (req, res) => { const webhookEvent = req.body; // Check if this is a message event if (webhookEvent.entry && webhookEvent.entry[0].changes && webhookEvent.entry[0].changes[0].value.messages) { const messageEvent = webhookEvent.entry[0].changes[0].value.messages[0]; const from = messageEvent.from; // The user's phone number const messageText = messageEvent.text.body; // The message content // Chatbot logic to respond to the message let responseMessage; // Basic chatbot responses (you can expand this logic) if (messageText.toLowerCase().includes('hello')) { responseMessage = 'Hello! How can I assist you today?'; } else if (messageText.toLowerCase().includes('price')) { responseMessage = 'Our products range from $10 to $100. How can I help with pricing?'; } else if (messageText.toLowerCase().includes('bye')) { responseMessage = 'Goodbye! Have a great day!'; } else { responseMessage = 'Sorry, I did not understand that. Can you please rephrase?'; } // Send the response back to the user sendMessage(from, responseMessage); } // Send a 200 OK response back to WhatsApp res.sendStatus(200); }); // Verification route to verify the webhook with WhatsApp app.get('/webhook', (req, res) => { const verifyToken = process.env.VERIFY_TOKEN || 'your_verify_token'; const mode = req.query['hub.mode']; const token = req.query['hub.verify_token']; const challenge = req.query['hub.challenge']; // Validate the webhook token if (mode && token === verifyToken) { console.log('Webhook Verified'); res.status(200).send(challenge); } else { res.sendStatus(403); } });

You have to loop inside an array of numbers. Till today the api only allow to send to one number.

Here’s an example: const phoneNumbers = ['1234567890', '0987654321', '1123456789']; // Message you want to send const messageText = 'Hello from WhatsApp via Node.js!'; // Loop through each phone number and send a message phoneNumbers.forEach(async (phoneNumber) => { try { // Send the message const response = await axios.post( apiURL, { messaging_product: 'whatsapp', to: phoneNumber, type: 'text', text: { body: messageText } }, { headers: { 'Authorization': `Bearer ${accessToken}`, 'Content-Type': 'application/json' } } ); console.log(`Message sent to ${phoneNumber}:`, response.data); } catch (error) { console.error(`Failed to send message to ${phoneNumber}:`, error.response ? error.response.data : error.message); } });

@@manfraio Bother For Production level I want to send message on any Whatsapp like through my postmen, i take that number through user and send messages to that number is it possible?

@insidedocumentary3162 yes, but you cannot send any message. You have to send an template

@@manfraio Yes i should send Template now is there any setting i have to do on face portal, 2nd the code you provide is enough to send Template message to anyone without adding there number in Facebook Developer Test Number list
