This can be done by connecting softwares to BIM Track BCF server (see BCF Server).
By definition, any BCF API implementation is project-based and there is no concept of hubs in the specification. On the other hand, BIM Track projects are always stored within a hub, in a specific region. This requires anyone who wants to call the BCF API to know in advance which region to target. Users can access the exact URL to use for a project from the BIM Track web platform Integrations page.
Solibri and Vrex integrations were developed using the BCF REST API. However, most integrations with the BIM Track platform use the BIM Track REST API (see BIM Track REST API).
API reference documentation is available through Swagger UI (see BIM Track API - BCF API).
