Mailbox

What is the Mailbox??

• The mailbox refers to the messages and item lists sent to users to deliver in-game items.

• In channeling games, each game sends a message (reward) to the item delivery server. The game then retrieves the message from the delivery server and processes the rewards contained in the message.

Using the Mailbox

If you integrate any of the Kakao services listed below, you must integrate the mailbox server.

However, if the developer has their own mailbox and delivery server, they can use their server to distribute rewards.

• Kakao Reward-based Invitations

• Kakao Pre-registration

Implementation

• The mailbox and delivery functions do not provide a client API.
