How Junction connects to Jobpac

Jobpac can be read two ways: through its API with read-only credentials your administrator authorises, or, where it runs on your own servers, through a read-only database login. For servers that cannot be reached from the internet, the small Junction agent runs inside your network and connects outward, so no inbound firewall port is opened. Jobpac's API reference is public.

Questions you could ask about Jobpac

  • “Which projects are forecast to finish over budget?”
  • “What is the status of each subcontract claim this month?”
  • “Which vendors have invoices unpaid for more than 45 days?”

Answers come from your own system, with the source rows and the time the data was last updated.

What to know

  • Not available yet. Jobpac is in Junction's next wave of systems: widely used (markets: Australia) and readable without writing to it. We build each mapping from the vendor's own reference and check it with a customer who runs the system before calling it live.
  • Integration routes found in our research: REST API, SQL (direct DB, IBM i Db2).
  • When we researched this in October 2026 we found no MCP server from the vendor.
  • Payroll and personal data are denied by default.
