Frequently Asked Questions

Can I send a message from my own number?
Yes, you can send message from your number.
How to send multi-line text messages using API?
The message you want to send via the API needs to be encoded (encodeURIComponent). When you encode a new line, it is translated to '%0A'. This is how you will be able to accommodate different types of characters in the WhatsApp message.
