Large files — multipart upload (REST API)

For videos over 100MB (up to 1GB), use the chunked multipart flow. No MCP tool yet — call the REST API directly (Authorization: Bearer bp_your_key, base https://app.bulkpublish.com):

POST /api/media/multipart/create — body {contentType, sizeBytes} (exact size) → {r2Key, uploadId, partSize, partUrls, expiresIn}. partSize is fixed at 10MB (10485760); partUrls is one presigned PUT URL per part, in order; URLs expire in 3600s.
PUT each 10MB slice of the file to its partUrl and save the ETag response header per part. A failed part can be retried alone — a network drop never restarts the whole file.
POST /api/media/multipart/complete — body {r2Key, uploadId, parts: [{partNumber, etag}], fileName, mimeType, sizeBytes, width?, height?, duration?} → {file} (same media object as a normal upload; its id goes in mediaFileIds). Failed assembly auto-aborts the upload.

To cancel mid-flight: POST /api/media/multipart/abort — body {r2Key, uploadId} (frees stored parts)
400 = disallowed type or too large; 429 = storage quota exceeded

Bulk actions and approval

bulk_posts (delete | retry | reschedule) does not take requestApproval. A bulk retry on posts whose role lacks post:publish fails with 403 APPROVAL_REQUIRED — those posts must be submitted for team approval instead (create/update with requestApproval: true, then a teammate calls approve_post). Posts with approvalStatus "pending" or "rejected" are skipped by the scheduler even after a reschedule, until they are approved. See the schedule-post skill for the full approval flow.

Bulk pattern

For multiple files: call upload_media for each file, collect the returned IDs, then pass all IDs in mediaFileIds when creating the post.
