3. Set up Kakao Talk Channel Required

Kakao Sync provides a function to add the channel addition option to the Simple Signup Consent screen. This function enables users to decide whether to get news from your Kakao Talk Channel on the Consent screen when they log in. To use this function, you must do the followings:

What you do	Required

Connect Kakao Talk Channel Only after a Biz app is connected to a Business Channel, you can get permission to use particular user information.	O
Select a primary channel to be displayed on the Simple Signup Consent screen.	O

4. Request for the permission Required

In [Request for App Permissions] > [App Permissions], request for the permission of consent items for personal information in the List of app permissions to use user information required for the service.

Kakao does not provide too much user information without a clear purpose, and conducts a review before providing user information to protect user information.

After the review, we grant the permission to set the required user information as [Required] or [Optional] consent item. A consent item is an app setting to receive user information.

The permission request screen of consent item for personal information is organized as below.

You can select 🅐 Consent types in [Required consent], [Optional consent], or [Not request consent]. Need to select at least 1 consent item.

After checking and agreeing 🅑 Consent to the use of Kakao Login, select [Next] to enter the inputs related to signup and the reason for collection.

Kakao checks what each user's information is used for in the service, so you must enter the 🅓 Reason for Collection. Attach a confirmation document that proves the reason for the collection to the 🅒 Signup information that shows the items collected when signing up for the service. If it is difficult to attach confirmation documents due to site development, you can substitute a plan or design mockup.

After completing all items, select [Request] to review the app. It takes 3 to 5 business days. During the review, Kakao checks both the information entered and additional documents, as well as whether the current service's signup criteria and scope of information utilization are consistent with the app.

If you pass the review and are granted permission, you are ready to implement Kakao Sync. Upon completion of the review, the Kakao Sync Simple Signup feature settings on the app will be activated, and consent items for personal information is available. If the review is rejected, you will need to reapply by completing the deficiencies.

Note: User information

The [Required consent] items for user information is required to register or use the service. Users can complete KakaoSync Simple Signup only by agreeing to provide user information that is [Required consent].

The [Optional consent] user information corresponds to items that can complete Kakao Sync Simple Signup even if the user does not agree. User information that is [Optional consent] may not be provided by Kakao depending on whether the user agrees or not, so user information that is essential for signing up and using the service should not be set to [Optional consent].

If the purpose of requested user information is unclear or inappropriate, it may be rejected at review. For example, if you request to use shipping address information in a shopping mall that sells clothing and other items, then there is no problem, but if you request to use it in a service that does not require shipping address information, then it will be rejected.

Note: Re-review

If you need to provide additional user information after implementing Kakao Sync, you will need to request for review the user information again. The review will take the same amount of time as the review when Kakao Sync was implemented. The reviews are not required when disabling consent items or changing [Required consent] items to [Optional consent] items.
