The quality of public services can be improved by utilizing metaverse technology which enables public interaction and participation without geographical boundaries in 3D space. Metaverse uses blockchain as the underlying infrastructure, providing the advantages of transparency, immutability, and trust. In metaverse development, the API offers a flexible blockchain integration mechanism. However, there are technical problems that must be answered, such as the problem of integration complexity and integration security. Therefore, research is needed to develop an API-based blockchain and metaverse integration architecture that suits the needs of metaverse development. The author raises a case study of digital identity registration which is mapped from the e-KTP registration procedure in the real world. This research uses the Hyperledger Fabric platform to build a blockchain network with 3 peer nodes, while metaverse development utilizes Unity3D. REST API design is carried out using a domain-driven design approach to produce a microservice architecture that is in accordance with the business processes in the case study raised. Based on testing the functionality of the system prototype, it succeeded in meeting the requirements set out in the case study while maintaining responsive performance. The built API architecture is ensured to be safe from vulnerabilities that are tested with vulnerability scanning techniques.
