--- phase: 01-linkedin-video-upload plan: 01 type: execute depends_on: [] files_modified: - src/clients/linkedin.ts --- Implement the LinkedIn Videos API upload flow inside src/clients/linkedin.ts. Purpose: The existing linkedin client only supports text posts. LinkedIn video upload requires a 4-step REST API flow that differs from the v2 UGC posts API. This plan implements the complete upload pipeline as two exported functions. Output: Two new exported functions — `uploadVideo()` and `createVideoPost()` — that handle downloading a video from a public URL, chunking it, uploading it to LinkedIn, and publishing a post with the video attached. ~/.claude/get-shit-done/workflows/execute-plan.md ./summary.md @src/clients/linkedin.ts **Established patterns in this file:** - `resolveToken(args, customer)` handles both multi-tenant (Redis/OAuth) and env-var auth - `linkedinRequest(endpoint, token, method, body)` wraps fetch for `/v2` API calls - All exported functions accept `{ account?: string }` and optional `Customer` - `createToolAudit(customer.id, 'linkedin:action')` wraps calls for audit logging - Errors bubble as thrown `Error` instances (not wrapped in result objects) **LinkedIn Videos API facts (different from v2):** - Base: `https://api.linkedin.com/rest` (not `/v2`) - Required extra header: `LinkedIn-Version: 202501` - Init: `POST /rest/videos?action=initializeUpload` - Chunk upload: PUT to each `uploadUrl` from init response, `Content-Type: application/octet-stream` - ETag collected from each PUT response's `ETag` header - Finalize: `POST /rest/videos?action=finalizeUpload` - Poll: `GET /rest/videos/{encodedVideoUrn}` until `status === 'AVAILABLE'` - Post: `POST /rest/posts` (not `/v2/ugcPosts`) — post ID returned in `x-restli-id` response header - Chunk size: 4 MB (4,194,304 bytes); LinkedIn enforces min 2 MB except last chunk Task 1: Add linkedinRestRequest helper and uploadVideo() function src/clients/linkedin.ts Add a private `linkedinRestRequest` helper (mirrors `linkedinRequest` but uses `https://api.linkedin.com/rest` base and adds `LinkedIn-Version: 202501` header). Responses from init/finalize return 200 with JSON body; PUT chunk responses may return 200 or 204; always read ETag from the response header, not the body. Then add `uploadVideo(videoUrl, ownerUrn, accessToken): Promise` (returns video URN): Step 1 — Download: fetch the videoUrl, read as ArrayBuffer, get byte length. Use AbortSignal.timeout(120000) for large files. Step 2 — Initialize upload: POST /rest/videos?action=initializeUpload Body: { initializeUploadRequest: { owner: ownerUrn, fileSizeBytes: N, uploadCaptions: false, uploadThumbnail: false } } Extract from response.value: uploadInstructions (array), video (URN string), uploadToken. Step 3 — Upload chunks: Chunk size: 4,194,304 bytes. For each uploadInstruction, slice the buffer from firstByte to lastByte+1 and PUT to uploadUrl with Content-Type: application/octet-stream. Collect the ETag response header from each PUT (strip surrounding quotes if present). Use AbortSignal.timeout(60000) per chunk. Step 4 — Finalize: POST /rest/videos?action=finalizeUpload Body: { finalizeUploadRequest: { video: videoUrn, uploadToken, uploadedPartIds: [etag1, etag2, ...] } } Step 5 — Poll until AVAILABLE: GET /rest/videos/{encodeURIComponent(videoUrn)} Poll every 3 seconds, timeout after 90 seconds total, throw if status is 'FAILED'. Return videoUrn when status === 'AVAILABLE'. npx tsc --noEmit runs without errors after adding the function uploadVideo is exported-ready (used by Task 2), tsc clean Task 2: Add createVideoPost() exported function src/clients/linkedin.ts Add and export: ``` createVideoPost( args: { video_url: string; text: string; visibility?: 'PUBLIC' | 'CONNECTIONS'; account?: string }, customer?: Customer ): Promise<{ success: boolean; post_id: string; url: string }> ``` Implementation: 1. Resolve token with existing `resolveToken(args, customer)`. 2. Get profile with existing `getProfile(args, customer)` to build `authorUrn`. 3. Call `uploadVideo(args.video_url, authorUrn, accessToken)` → videoUrn. 4. Create post via POST /rest/posts (NOT /v2/ugcPosts — that endpoint does not support the video content field): Body: { author: authorUrn, commentary: args.text, visibility: args.visibility ?? 'PUBLIC', distribution: { feedDistribution: 'MAIN_FEED', targetEntities: [], thirdPartyDistributionChannels: [] }, content: { media: { id: videoUrn } }, lifecycleState: 'PUBLISHED', isReshareDisabledByAuthor: false } 5. The POST /rest/posts returns 201; the post URN is in the `x-restli-id` response header (not the JSON body). Read it with `res.headers.get('x-restli-id')`. 6. Wrap in createToolAudit (same pattern as createPost — log text.slice(0,100) + video_url). 7. Return { success: true, post_id, url: `https://www.linkedin.com/feed/update/${post_id}` }. Do NOT call linkedinRestRequest for the POST /rest/posts step — write an inline fetch since that call needs to read the 201 response header before res.json() would consume it. Throw a descriptive error if status is not 201. npx tsc --noEmit passes; grep -n 'createVideoPost' src/clients/linkedin.ts shows the export createVideoPost is exported, tsc clean, audit logging included Before declaring plan complete: - [ ] `npx tsc --noEmit` passes with zero errors - [ ] `grep -n 'uploadVideo\|createVideoPost\|linkedinRestRequest' src/clients/linkedin.ts` shows all three symbols - [ ] No existing functions (`getProfile`, `createPost`, `searchConnections`, `sendMessage`) are modified - uploadVideo() implements all 5 steps: download, init, chunk-PUT with ETag collection, finalize, poll - createVideoPost() uses /rest/posts (not /v2/ugcPosts) and reads post ID from x-restli-id header - Chunk size is 4,194,304 bytes - Poll timeout is 90 seconds with 3-second intervals - TypeScript compiles clean - Audit logging matches existing createPost pattern After completion, create `.planning/phases/01-linkedin-video-upload/01-01-SUMMARY.md`: # Phase 01 Plan 01: LinkedIn Video Upload Client Summary **[one-liner of what shipped]** ## Accomplishments ## Files Created/Modified ## Decisions Made ## Issues Encountered ## Next Step Ready for 01-02-PLAN.md
