Prerequisites
This document explains what you have to do before using the Kakao Talk Messaging APIs.
Set Kakao Talk Sharing success callback
Kakao Talk Sharing success callback is a function that informs you that the message has been successfully sent to the selected friends or chatroom through the specified callback URL.
To use this function,
- Go to [My Application] > [Message] > [Kakao Talk Sharing Callback], and click [Register callback].
- Select 'GET' or 'POST' for a request method, and set the Callback URL of the service server to receive a callback from the Kakao server.
To see the details on the callback request, refer to Reference Information > Kakao Talk Sharing success callback.
No. Because you can see the result of sending a message in the response, the callback function is not neccessary for the Kakao Talk Messaging API.
Allow firewall exceptions
If your service uses Kakao Talk Sharing success callback, you must allow Kakao IP addresses.
If you want to configure a preview page before sending a Kakao Talk Sharing message, you must allow firewall exceptions as described in DevTalk. Otherwise, it takes much time to send a Kakao Talk Sharing message or an image is not displayed because your service server blocks the Kakao scrapping server.
