Treat `FAILED` and `ARCHIVED` as terminal. This cookbook assumes you already have your Partner ID, a Bearer JWT for CKG upload, `organization_id`, and a valid FHIR R4 bundle JSON file. ```typescript theme={"theme":{"light":"github-dark","dark":"material-theme-darker"}} import fs from "fs"; const BASE_URL = "https://sdp.suki.ai"; async function uploadAndWaitForCkg(organizationId: string, bundlePath: string) { const params = new URLSearchParams({ organization_id: organizationId, correlation_id: "encounter-abc-123", }); const urlRes = await fetch(`${BASE_URL}/api/v1/fhir-push/upload-url?${params}`, { headers: { Authorization: `Bearer ${sdpJwtBearerToken}` }, }); if (!urlRes.ok) { throw new Error(`Request upload URL failed: ${urlRes.status}`); } const { transaction_id: transactionId, upload_url: uploadUrl } = await urlRes.json(); const bundle = fs.readFileSync(bundlePath, "utf-8"); const uploadRes = await fetch(uploadUrl, { method: "PUT", headers: { "Content-Type": "application/json", "x-goog-content-length-range": "0,524288000", }, body: bundle, }); if (!uploadRes.ok) { throw new Error(`FHIR upload failed: ${uploadRes.status}`); } for (let i = 0; i < 120; i++) { const statusRes = await fetch( `${BASE_URL}/api/v1/fhir-push/status/${transactionId}`, { headers: { Authorization: `Bearer ${sdpJwtBearerToken}` } } ); if (!statusRes.ok) { throw new Error(`Get ingestion status failed: ${statusRes.status}`); } const { status } = await statusRes.json(); if (status === "COMPLETED") return "COMPLETED"; if (status === "FAILED" || status === "ARCHIVED") return status; await new Promise((r) => setTimeout(r, 5000)); } throw new Error("Timed out waiting for CKG ingestion"); } const outcome = await uploadAndWaitForCkg(organizationId, "my-fhir-bundle.json"); if (outcome === "COMPLETED") { // Generate Patient Summaries } ``` ```python theme={"theme":{"light":"github-dark","dark":"material-theme-darker"}} import time import requests BASE_URL = "https://sdp.suki.ai" def upload_and_wait_for_ckg(organization_id: str, bundle_path: str) -> str: url_res = requests.get( f"{BASE_URL}/api/v1/fhir-push/upload-url", params={ "organization_id": organization_id, "correlation_id": "encounter-abc-123", }, headers={"Authorization": f"Bearer {sdp_jwt_bearer_token}"}, timeout=30, ) url_res.raise_for_status() data = url_res.json() transaction_id = data["transaction_id"] upload_url = data["upload_url"] with open(bundle_path, "rb") as f: upload_res = requests.put( upload_url, headers={ "Content-Type": "application/json", "x-goog-content-length-range": "0,524288000", }, data=f, timeout=300, ) upload_res.raise_for_status() for _ in range(120): status_res = requests.get( f"{BASE_URL}/api/v1/fhir-push/status/{transaction_id}", headers={"Authorization": f"Bearer {sdp_jwt_bearer_token}"}, timeout=30, ) status_res.raise_for_status() status = status_res.json().get("status") if status == "COMPLETED": return "COMPLETED" if status in ("FAILED", "ARCHIVED"): return status time.sleep(5) raise TimeoutError("Timed out waiting for CKG ingestion") outcome = upload_and_wait_for_ckg(organization_id, "my-fhir-bundle.json") if outcome == "COMPLETED": # Generate Patient Summaries pass ``` ## Common mistakes * Starting generation before ingestion status is `COMPLETED`. * Letting the upload URL expire (**15 minutes**) before the PUT. * Using different identifiers in the FHIR bundle than later `fhir_encounter_id` / `fhir_practitioner_id` values. * Sending `sdp_suki_token` on CKG upload instead of the Bearer JWT. ## Other cookbooks
