4. Apply Kakao Sync Required

To apply Kakao Sync, you need to input the required information and request permission for user information that your service needs.

Input information

If your service applies Kakao Sync, users can simply sign up by consenting to the service terms and the Provision of Personal information on the Simple Signup Consent screen. Thus, make sure to input the correct information.

1. Select the '카카오싱크 신청(Apply for Kakao Sync)' menu in Kakao Business Admin Center.
2. If you have not saved a verified phone number in your Kakao Account, you are requested to input your phone number by clicking [연락처 등록하기(Register contact)]. The registered phone number is used for users to contact if errors occur while adopting Kakao Sync service. If your phone number has already been saved, you can skip this step.
3. Select a type of operating your service. Ensure that you cannot change this type later on after selecting an option in this step.
   3-1. If you are operating your own website, not using a web hosting service, select '호스팅사에 속하지 않는 독립몰(If operating your own website)'.
   3-2. If you are using a web hosting service, select '호스팅사를 이용하고 있는 경우(If using a web hosting service)', and then select one of the hosting services among 카페24(cafe24), 식스샵(sixshop), 메이크샵(MakeShop), 아임웹(I'mweb), 위사(WISA) and 가비아(gabia). If you are using the web hosting service affiliated with Kakao, you can request a review only for CI among user information in Kakao Business Admin Center, and then input the rest information in the web hosting service website. If you are not using one of the supported web hosting services, you cannot use Kakao Sync. In this case, ask the web hosting service you are using for their plan to adopt Kakao Sync.
   
4. If you apply for Kakao Sync for the first time, enter the information in 카카오 로그인시 개인정보제공 항목 검수(Review for Provision of Personal Information for Kakao Login). This review is required to protect personal information, and Kakao reviews the personal information to be provided. After a review is passed, you can ask for consent to the personal information in your service.

Review for Provision of Personal Information for Kakao Login

You can decide what kinds of user information you will collect or whether to set each user information to Required or Optional consent item. However, to retrieve some user information, a review is required to get permission. Some user information can be set as a 'Required consent' item only after registering a business registration number, or this review is passed.

🅐 Select the checkboxes of user information to be provided. 🅑 Select the '필수 수집 항목(Required collecting data)' or '선택 수집 항목(Optional collecting data)' option for each user information you selected.

'필수 수집 항목(Required collecting data)' refers to the information required for a service and users must input when signing up. Thus, if users do not provide or agree to provide, Simple signup or login is not completed. In the case of the '선택 수집 항목(Optional collecting data)', users can finish login or Simple signup without consent to the user data. If your service must get specific user information, set it to '필수 수집 항목(Required collecting data).

🅒 Input the purpose of collecting the user information in your service in '수집 사유(Reason for collecting data)'. This field is required because Kakao needs to check how each user information is used in your service. 🅓 In '서비스 회원가입 링크 URL(URL of signup for service)' under '추가 서류 제출(Submit additional material)', input the URL where we can check what kinds of user information your service collects during a signup process. Additionally, upload material to prove the reason for collecting the user information by clicking '업로드(Upload)'. If you are operating a service, you must attach the current signup page. If the signup page has not been developed yet, you can upload a plan or a design draft instead for the material.

After settings above, click [신청하기(Apply)] to ask for a review.

If the purpose for collecting user information is not clear or proper, you may not get permission to use the user information. For example, if an online store for clothes chooses to get users' shipping addresses to deliver clothes, the request is surely accepted. However, if a service that does not need shipping addresses requests shipping addresses, the service may fail to get permission through the review.

Kakao refrains from providing unnecessary user information. Therefore, you need to choose only the user information to be used in your service and decide to collect the user information optionally or mandatorily according to your service's needs.

After asking for review

After you input the information to use Kakao Sync, Kakao reviews the items of personal information to be provided you have input and the attached materials. It takes 3 to 5 business days to review. Kakao checks if the request information coincides with your service information. After a review is passed, your service can get permission to use personal information and use related functions.

To see the review result, select '검수 결과 확인(Check review result)' in the '카카오싱크 신청(Apply for Kakao Sync)' menu. If a review is passed, proceed to the next step. If failed, we will inform you of a rejection reason.

To get permission to use more user information in your service or request a review again after rejection, go through the procedures in the same way as applying for Kakao Sync described above. It also takes the same period, 3 to 5 days. To withdraw some permissions, you can simply change the settings in [My Application] > [Kakao Login] > [Consent Items].

5. Manage service terms Required

After a review is passed, you can enable the Simple Signup function that enables your service to obtain consent to all service terms at once on the Simple Signup Consent screen.

Go to [My Application] > [Kakao Login] > [Simple Signup], and then add a new service term or modify the registered service term by referring to Set Simple Signup.

Note that only the app that has been passed the review can use the Simple Signup function.

6. Set up test environment

If you are already using Kakao Login or other Kakao APIs or have any issues while operating your service, you need to set up a test environment for Kakao Sync development. Make sure that you should set up after Kakao Sync review is passed.

1. In Kakao Developers, go to [My Application] > [General] > [Test App Information] and create a test app.
2. In Kakao Talk Channel Admin center, click [개발자용 채널 만들기 (Create a channel for developers)], and then create a test channel.
3. In Kakao Business Admin Center, select [카카오 싱크(Kakao Sync)], and connect a test app and a test channel. Then, set a primary channel.
4. In Kakao Developers, go to [My Application] > [General] and click [Sync permission with a test app] under 'Test App Information' to apply your app information to a test app.
5. Configure your test app if necessary,and then test with the test app.
