# Send Message



pay attention

You can use the "Send Message" API in one case only:

You reply to a message that the client sent, within 24 hours since the client sent his last message.

If you send a message to a new client, or try to send a message to an old client (old client means that 24 hours since client's last message has passed), you must use the "Send Template Message" API instead.

If you send a template message to the client, and the client did not reply yet, and you want to send another message to him, you must use the template message again.

After the first 1,000 messages each month, every additional message is billed at 0.5 credits.

# Remarks

  • You can use the "Send Message" API in one case only - for reply to a message that the client sent, within 24 hours since the client sent his last message. If you send a message to a new client, or try to send a message to an old client (old client means that 24 hours since client's last message has passed), you must use the "Send Template Message" API instead. If you send a template message to the client, and the client did not reply yet, and you want to send another message to him, you must use the template message again.
  • You can only send a message to private people, not groups.
  • 24 hours session conversation starts when you send a message to the client.
  • Every time the user replies, the template message session resets. which means that you don't have to use template message during this 24 hours template message session.
