[Notice] Announcing Enhancements to MSU Builder
As part of our ongoing commitment to enhancing the builder experience and fostering a more robust development environment, we are pleased to announce significant upgrades to MSU Builder.
These enhancements are designed to introduce a more structured development path, improve convenience, and provide an integrated, supportive platform for our community.
■ Key Enhancements to MSU Builder
We have introduced several new features to MSU Builder to support this new standard.
| Feature | Description |
| Builder Account System | Builders can now create and manage a personal account directly within MSU Builder. |
| Sandbox API Key Application | A simplified application process for a usage-limited Sandbox API key is now available through the new builder account system. |
| Unified Application Process for Live Services | Builders will be able to apply for Synergy App review and a Live API Key simultaneously through their builder account. |
We are committed to the continuous improvement of this platform and plan to introduce additional features, including real-time API usage data, in subsequent updates.
■ A New Standard for API Usage
We are establishing a clear operational model for API usage to support your development lifecycle.
- Sandbox API Key → Provided strictly for testing and development of Synergy Apps prior to launch.
- Live API Key → Mandatory for a service to go live. Also a prerequisite for a project to be formally recognized as a contribution to the MSU Builder ecosystem.
■ Updated API Key Application Process
To centralize and secure our processes, all future API key applications will be managed exclusively through MSU Builder.
- A KYC (Know Your Customer) or KYB (Know Your Business) verification will be a required step for all API key applicants.
- Until the next platform update, this verification for Sandbox API key applications will be conducted via email.
- Applicants are required to monitor the inbox of the email address submitted during account registration for further instructions.
⚠️ Important Notes
- All builders applying for a new API key must use the application process on MSU Builder.
- Applicants for Sandbox API keys should expect a separate email to complete the mandatory KYC/KYB verification. Failure to complete this step will delay the application process.
- For existing builders, it is required to connect your pre-registered wallet within the new system to ensure the continued functionality of your current API key.
We believe these updates will provide a more efficient and secure foundation for the valuable work you do.
Thank you for your continued commitment to the MapleStory Universe ecosystem.
