Kakao Talk Channel

REST API

This document describes how to integrate Kakao Talk Channel APIs into your service with a REST API.

IMPORTANT: Providing a new API

We provide the v2 version for checking Kakao Talk Channel relationship API. You can find information of the v1 API in a separate document.

Note

To get an alarm when a user adds or blocks your Kakao Talk Channel, use Kakao Talk Channel callback.

This API enables you to check if a specific user has added or blocked your Kakao Talk Channel connected to your service app.

Send a GET request with the access token in the header. If you are an administrator, you can also use the app's Admin key to request. Make sure to use the app's Admin key only in the server.

Each channel object in the response contains detailed information, such as whether the user adds or blocks the Kakao Talk Channel currently and the time when the channel has been added or blocked.

If an error occurs because the user did not consent to the consent item, you can request consent from the user again by Requesting additional consent as needed.

You must use either app(service user ID of Kakao Account) or phone(mobile phone number of Kakao Talk) for id, and input the appropriate value for the specified type. Schemas can be specified differently according to customer files, so pass the right value for the corresponding customer file in JSON array format as the sample below.

If successful, file_id, request_count(the number of users you requested to add to the customer file), and success_count(the number of users who have successfully added) return. Make sure that request_count may differ from success_count depending on situations.

What if some users are not added to the customer file?

To do so, the user must be linked to your service through a Kakao Account. -If 'user_type' is set to 'phone', the value of 'id' must be the phone number used to sign up for Kakao Talk.
