Hi @비토즈Tr ,
You will need developer role to create project and then use Experience Platform APIs. This gives you access to users, groups, and entitlements for Adobe products and services.
Steps: Login into Developer console --> Create a Project --> Add Experience Platform API service to the project --> Provide API access to the created Project from AEP console Permissions section--> Generate credentials, Token and start using API.
