Overview

The Kakao API provides login, messaging, social sharing, and map services for the KakaoTalk platform, which is dominant in South Korea. It uses OAuth 2.0 for user authentication and lets you build apps that send messages, access profile data, and interact with Kakao services. You will need to register your app at developers.kakao.com to get an API key.

Beginner Tip

Kakao has separate keys for different services — use the REST API key (not the JavaScript key) for server-side calls. Start with the token info endpoint to verify your access token is valid before making other API calls.

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

-401 KOE101: Invalid token Access token is expired or malformed

✓ Re-authenticate the user to get a fresh access token, or use the refresh token to obtain a new one via the token endpoint

-402: Token does not exist Token was revoked or the user logged out

✓ Redirect the user to the Kakao login flow to re-authorize your app

-403: No permission for this API Required scope was not requested during authorization

✓ Add the needed scope such as profile or account_email to your authorization request at developers.kakao.com

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
