The API server is a gRPC/REST server which exposes the API consumed by the Web UI, CLI, and CI/CD systems.  This command runs API server in the foreground.  It can be configured by following options.

Usage:
  argocd-server [flags]
  argocd-server [command]

Examples:
  # Start the Argo CD API server with default settings
  $ argocd-server

  # Start the Argo CD API server on a custom port and enable tracing
  $ argocd-server --port 8888 --otlp-address localhost:4317

Available Commands:
  completion  Generate the autocompletion script for the specified shell
  help        Help about any command
  version     Print version information
