  title: TigerGraph REST++ API
  description: >-
    Specification of the built-in TigerGraph REST++ API exposed by the TigerGraph
    database server. REST++ provides built-in endpoints to read, upsert, and delete
    vertices and edges, run installed GSQL queries as dynamic endpoints, find paths,
    retrieve schema metadata, run loading jobs, and issue bearer authentication
    tokens. By default REST++ listens on port 9000 (unified on port 14240 in
    TigerGraph 3.x and later); the GSQL server listens on port 14240. TigerGraph
    Savanna (Cloud) serves the same surface over HTTPS at a per-workspace host.
