  description: "Upload and manage files used in assessments, such as source code archives.\n\nAll endpoints require an _organization_\
    \ API key.\n\n## Upload flow\n\nResources use a multipart S3 upload. The full flow is:\n\n1. **Create** — `POST /api/v1/organizations/:organizationId/resources`\
    \ — initiates an upload and returns a resource ID. Status is `initiated`.\n2. **Get part URLs** — `POST /api/v1/resources/:resourceId/parts`\
    \ — provide a list of part numbers and receive a corresponding list of presigned S3 `PUT` URLs.\n3. **Upload parts** —\
    \ `PUT` each part directly to its presigned URL. Save the `ETag` header from each part response.\n4. **Commit** — `POST\
    \ /api/v1/resources/:resourceId/commit` — submit the part numbers and ETags. Optionally include a `sha256` checksum of\
    \ the full file for server-side integrity verification. Status moves to `processing`.\n5. **Poll** — `GET /api/v1/resources/:resourceId`\
    \ — wait until status is `ready` (or `failed`).\n6. **Delete** — `DELETE /api/v1/resources/:resourceId` — the resource\
    \ can be manually deleted when required. Status moves to `deleted`.\n\nThe maximum part size is 5 GiB. Parts must be at\
    \ least 5 MiB each, except the final part which may be smaller.\nBreaking large files into multiple parts allows failed\
    \ parts to be retried individually rather than restarting the entire upload.\n\n## Resource statuses\n\n| Status | Meaning\
    \ |\n|---|---|\n| `initiated` | Upload in progress — parts not yet committed |\n| `processing` | Commit received — server\
    \ is validating and storing |\n| `ready` | Available to use in assessments |\n| `failed` | Processing failed — see `statusMessage`\
    \ for details |\n| `deleted` | Deleted |\n\n## Example\n\nThis snippet shows how to upload an example file named `source.tar.gz`\
    \ using the API multipart upload feature.\nIt uses the `fetch` API and assumes a Node.js environment with `fs/promises`\
    \ available.\n\n```typescript\nimport fs from \"node:fs/promises\";\nimport crypto from \"node:crypto\";\nconst BASE =\
    \ \"https://console.xbow.com\";\nconst ORG_ID = \"your-organization-id\";\nconst API_KEY = \"your-api-key\";\nconst PART_SIZE\
    \ = 5 * 1024 * 1024; // 5 MiB minimum\nconst API_VERSION = \"next\";\n\nconst headers = { \"Authorization\": `Bearer ${API_KEY}`,\
    \ \"X-XBOW-API-Version\": `${API_VERSION}` };\n\n// 1. Create resource\nconst created = await fetch(`${BASE}/api/v1/organizations/${ORG_ID}/resources`,\
    \ {\n  method: \"POST\",\n  headers: { ...headers, \"Content-Type\": \"application/json\" },\n  body: JSON.stringify({\
    \ name: \"My source\", fileName: \"source.tar.gz\", type: \"source\" }),\n}).then(r => r.json());\nconst resourceId =\
    \ created.id;\n\n// 2. Split file into parts and request presigned URLs\nconst file = await fs.readFile(\"source.tar.gz\"\
    );\nconst partCount = Math.ceil(file.length / PART_SIZE);\nconst { parts: partUrls } = await fetch(`${BASE}/api/v1/resources/${resourceId}/parts`,\
    \ {\n  method: \"POST\",\n  headers: { ...headers, \"Content-Type\": \"application/json\" },\n  body: JSON.stringify({\
    \ parts: Array.from({ length: partCount }, (_, i) => i + 1) }),\n}).then(r => r.json());\n\n// 3. Upload each part to\
    \ S3 directly, collect ETags\nconst uploadedParts = await Promise.all(partUrls.map(async ({ partNumber, url }) => {\n\
    \  const chunk = file.slice((partNumber - 1) * PART_SIZE, partNumber * PART_SIZE);\n  const res = await fetch(url, { method:\
    \ \"PUT\", body: chunk });\n  return { partNumber, eTag: res.headers.get(\"ETag\").replaceAll('\"', \"\") };\n}));\n\n\
    // 4. Commit (sha256 is optional but recommended for integrity verification)\nconst sha256 = crypto.createHash(\"sha256\"\
    ).update(file).digest(\"hex\");\nawait fetch(`${BASE}/api/v1/resources/${resourceId}/commit`, {\n  method: \"POST\",\n\
    \  headers: { ...headers, \"Content-Type\": \"application/json\" },\n  body: JSON.stringify({ parts: uploadedParts, sha256\
    \ }),\n}).then(r => r.json());\n\n// 5. Poll until ready\nlet resource;\ndo {\n  await new Promise(r => setTimeout(r,\
    \ 5000));\n  resource = await fetch(`${BASE}/api/v1/resources/${resourceId}`, { headers }).then(r => r.json());\n} while\
    \ (resource.status === \"processing\" || resource.status === \"initiated\");\n\nif (resource.status !== \"ready\") throw\
    \ new Error(`Upload failed: ${resource.statusMessage}`);\nconsole.log(\"Resource ready:\", resource.id);\n\n// 6. Delete\
    \ when no longer required\nawait fetch(`${BASE}/api/v1/resources/${resourceId}`, {\n  method: \"DELETE\",\n  headers,\n\
    });\n```"

- aid: xbow:xbow-webhooks-api
  name: Xbow Webhooks API
  description: "Manage webhook subscriptions and receive event notifications.\n\nWhen creating an organization, you may provide\
    \ an HTTPS webhook URL to receive events related to the organization's resources.\n\nWe implement _best-effort_ delivery\
    \ of events, soon after they occur. We will not retry delivery if it fails for any reason.\n\n## Webhook Versioning\n\n\
    Webhook payloads follow the API version of the subscription. When a version reaches its end-of-life date, webhook subscriptions\
    \ for that version will stop emitting events. Ensure your integration is updated to a supported version before the EOL\
    \ date.\n\n## Signature Verification\n\nEach request will be a `POST` request sent with the following headers:\n* `X-Signature-Timestamp`:\
    \ A Unix timestamp in seconds.\n* `X-Signature-Ed25519`: An hex string representing an Ed25519 signature of the concatenation\
    \ of the timestamp and the request body, signed with XBOW's private key.\n\nYou must verify the signature using the public\
    \ key from the `GET /api/v1/meta/webhooks-signing-keys` endpoint.\nYou must verify that the timestamp is within a valid\
    \ range from the current time to prevent replay attacks. An example of a valid range might be +/-5 minutes.\nYou should\
    \ respond with a 2xx status code if the signature is valid, and a 401 status code otherwise.\nBefore organization creation,\
    \ we will send two test `ping` events. One signed with XBOW's private key, and one signed with an invalid key. This allows\
    \ you to verify that your signature verification is working correctly.\n\nFor example, if you're using Node.js:\n\n```javascript\n\
    import consumers from \"node:stream/consumers\";\n\n// Fetch the public key from the API (cache this - it rarely changes)\n\
    const keysResponse = await fetch(\"https://console.xbow.com/api/v1/meta/webhooks-signing-keys\", {\n  headers: { Authorization:\
    \ \"Bearer your-api-key\", \"X-XBOW-API-Version\": \"2026-02-01\" }\n});\nconst keys = await keysResponse.json();\nconst\
    \ publicKeyBase64 = keys[0].publicKey;\n\n// Import the public key (SPKI format, base64-encoded)\nconst publicKey = await\
    \ crypto.subtle.importKey(\n  \"spki\",\n  Buffer.from(publicKeyBase64, \"base64\"),\n  { name: \"Ed25519\" },\n  false,\n\
    \  [\"verify\"],\n);\n\nconst timestamp = req.headers[\"x-signature-timestamp\"];\nconst timestampTime = parseInt(timestamp,\
    \ 10);\nconst now = Math.floor(Date.now() / 1000);\nconst isValidTimestamp = (Math.abs(now - timestampTime) < 300);\n\n\
    if (!isValidTimestamp) {\n  throw new Error(\"Invalid timestamp\");\n}\n\nconst signature = req.headers[\"x-signature-ed25519\"\
    ];\nconst body = await consumers.text(req.body);\nconst isVerified = await crypto.subtle.verify(\n  { name: \"Ed25519\"\
    \ },\n  publicKey,\n  Buffer.from(signature, \"hex\"),\n  Buffer.from(timestamp + body),\n);\n\nif (!isVerified) {\n \
    \ throw new Error(\"Invalid request signature\");\n}\n```\n\n## Upgrading webhook subscriptions\n\nEach subscription is\
    \ pinned to an API version. When we release a new version, you should plan to migrate your subscriptions to it. Once a\
    \ version reaches its end-of-life date we stop emitting events for subscriptions on that version, so an unmigrated subscription\
    \ will silently stop receiving deliveries.\n\nUpgrading is a single `PATCH` per subscription. The snippet below lists\
    \ every subscription on your organization, bumps any pinned to a given older version to a specified newer one, and skips\
    \ subscriptions on `next` (which track the latest stable version automatically). It uses cursor pagination so it works\
    \ for organizations with any number of subscriptions.\n\n```typescript\n// Upgrade webhook subscriptions from 2026-02-01\
    \ -> 2026-04-01. Skip \"next\".\nconst BASE = \"https://console.xbow.com\";\nconst ORG_ID = \"your-organization-id\";\n\
    const API_KEY = \"your-api-key\";\nconst OLD = \"2026-02-01\";\nconst NEW = \"2026-04-01\";\n\nconst headers = { Authorization:\
    \ `Bearer ${API_KEY}`, \"X-XBOW-API-Version\": NEW };\n\nasync function* paginate<T>(url: string): AsyncGenerator<T> {\n\
    \  let cursor: string | null = null;\n  do {\n    const u = new URL(url);\n    if (cursor) u.searchParams.set(\"cursor\"\
    , cursor);\n    const res = await fetch(u, { headers });\n    if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);\n\
    \    const page = (await res.json()) as { items: T[]; nextCursor: string | null };\n    yield* page.items;\n    cursor\
    \ = page.nextCursor;\n  } while (cursor);\n}\n\ntype Sub = { id: string; apiVersion: string };\nfor await (const wh of\
    \ paginate<Sub>(`${BASE}/api/v1/organizations/${ORG_ID}/webhooks`)) {\n  if (wh.apiVersion === \"next\") { console.log(`skip\
    \   ${wh.id} (next)`); continue; }\n  if (wh.apiVersion !== OLD)    { console.log(`skip   ${wh.id} (${wh.apiVersion})`);\
    \ continue; }\n  const res = await fetch(`${BASE}/api/v1/webhooks/${wh.id}`, {\n    method: \"PATCH\",\n    headers: {\
    \ ...headers, \"Content-Type\": \"application/json\" },\n    body: JSON.stringify({ apiVersion: NEW }),\n  });\n  if (!res.ok)\
    \ throw new Error(`${res.status} ${await res.text()}`);\n  console.log(`bump   ${wh.id} ${OLD} -> ${NEW}`);\n}\n```\n\n\
    An `apiVersion`-only `PATCH` does not re-validate your endpoint, so the upgrade is cheap and safe to run for many subscriptions\
    \ at once. A `PATCH` that changes `targetUrl` does re-send the validation pings described above, and must receive a 2xx\
    \ for the valid ping to succeed."
