Guides

These guides walk you through the integration in the order you'll actually build it — from the first authenticated call to the production checklist.

• Your first check — from zero to a finished report, with a runnable script you can execute against the live API.
• The question-answer loop — the state machine your code must implement: question types, answer shapes, and the FUNCTION questions that interrupt the loop.
• Advanced question UI — detailedType and detailedTypeData, specialized widgets versus the generic fallback, and paging or searching large option lists.
• Changing answers and recovering state — stepping back to earlier answers and rebuilding a check after your client loses its state.
• The overview — fetching, editing, and confirming the overview, and the 403 error (OVERVIEW_CAN_NOT_BE_SKIPPED) you hit when you skip the fetch.
• The report — fetching the report as JSON or PDF, which ends the check, and the history endpoints for finished checks.
• Displaying the report — how XUND's own reference integration renders each report field (score, urgency, treatment advice, warning signs), and why following it is the safe default for the acceptance test.
• Lookups — the read-only endpoints outside the check flow: Content Library, Medical Services, and Specializations.
• Webhooks — get notified on your server when a check finishes, and verify each request.
• Error handling — the error codes the API returns, what triggers each one, and how to recover.
• Going live — the compliance and operational checklist for moving from prototype to production.
