Sep 30 - Patch Note

▶ Synergy App and API Key Self-Service

• Within the "API & Apps" menu, Maplers can now register up to 5 Synergy Apps per account and obtain an API key per Synergy App.
• Maplers can view and manage their registered Synergy Apps and API key information directly within the menu.

▶ API Key Issuance and Synergy App Registration

• By entering a Synergy App's name and registering it, a Test API key is issued immediately without any separate review process.
• The Test API key is automatically granted full permissions for general query APIs.
• Maplers can manually extend their Test API keys starting from 30 days prior to expiration.
• After developing a Synergy App using a Test API key, Maplers can apply for a Live Review. Once the review is approved, the API key's call limit is increased, and the app's status will transition to "Live".

▶ OAuth Issuance

• After the Live Review has been approved, Maplers can then obtain OAuth credentials.

▶ Cleanup of Unapproved API Key Applications Submitted Before August 1, 2026

• API key applications submitted before August 1, 2026 that remain unapproved (Pending or Rejected status, with no linked app) have been removed.
• Applications submitted on or after August 1, 2026 that are still under review are unaffected.
• All approved applications, along with their associated apps and API keys, are unaffected.

※ This update was applied as part of the scheduled maintenance on October 1, 2026.

※ No action is required if your existing application or API key falls outside the scope above.
