Q. I cannot retrieve any friends.

{
  "elements": [],
  "total_count": 0,
  "after_url": null,
  "favorite_count": 0
}

If none of friends is retrieved even after I completed all prerequisties,

• Your team member may not be your Kakao Talk friends.
• Your team member may be blocked or hidden. In this case, unblock or unhide the friend first.

To see more about conditions to retrieve a list of friends, refer to Kakao Talk Social > Usage policy.

Q. How can I test the Retrieving list of friends API?

To retrieve the list of Kakao Talk friends through the Retrieving list of friends API and the Friend picker, you must test before Requesting permission.

After implementing the function to retrieve a list of friends by referring to the development guide for the platform you develop, test to check if your app's team members are normally retrieved as follows:

1. Go to [My Application] > [Kakao Login] > [Consent items], and then set the Friends List in Kakao Service scope to 'Consent during use' under Personal Information.
2. Implement the function to retrieve a list of friends by referring to the development guide for the platform you develop. If an error occurs, refer to the error cases in DevTalk.
3. Log into your app with your Kakao Account and consent to 'Friends List in Kakao Service' scope.
4. If any team member is not registered, add the persons to be tested as team members. If a person invited as a team member does not have a Kakao Developer's account, ask them to sign up for Kakao Developers with the Kakao Account.
5. Ask the team members to log in to your app with their Kakao Accounts and consent to the 'Friends List in Kakao Service' scope.
6. Request a list of friends, and then check if the team members are successfully retrieved.
   IMPORTANT: Only the team members who are linked to your app and consented to the 'Friends List in Kakao Service' scope are retrieved.
