Approaches for transparently interfacing with a third party version control system (VCS) are provided. In one approach, an enterprise application integration (EAI) system comprises an integrated development environment (IDE) client, a repository, an API, and an API implementation. The IDE client enables a user to develop one or more functional components that can be used or executed to derive one or more enterprise application functionalities. The repository interacts with the IDE client to save and access the one or more functional components. The API is invoked by the repository to interact with any VCS. The API implementation enables the repository, by way of invoking the API, to interact with a VCS, which is an external VCS that is not provided as part of the EAI system.
