Institution Application Process
For administrators (with function permission: [User Management] as well as [OpenAPI Application]), you need to complete the Open API Services application, then grant Open API Access to users within your organization, allowing them to create their own app keys and secret keys (AK/SK) and manage accounts through API.
For non-administrator users, you must first contact an administrator to enable Open API Access, then go to create api keys application and, following the page instructions, create your personal Open API Keys application in the Developer Center.
