Features Comparison: What Can Each Do?
Message Types
Both support the same core message types. No winner here.
javascript
// TWILIO
await twilioClient.messages.create({
from: 'whatsapp:+1234567890',
to: 'whatsapp:+9876543210',
body: 'Hello from Twilio'
});// WHATSAPP API
await axios.post(/v1/sendText, {
chatId: '9876543210',
