Dropspace

Dropspace API Skill

Multi-platform social media publishing with AI-generated content, media generation, per-post analytics, and persona-based writing styles.

Setup

Set your API key:

export DROPSPACE_API_KEY="ds_live_..."  # from dropspace.dev/settings/api

Base URL: https://api.dropspace.dev Auth header: -H "Authorization: Bearer $DROPSPACE_API_KEY"

Also available as MCP server: npx @jclvsh/dropspace-mcp Machine-readable docs: llms.txt | OpenAPI

API Key Scopes

Keys can be scoped: read, write, delete, publish, generate, admin.

Missing scope returns 403 with AUTH_002.

Audit Logging

Destructive/sensitive API operations are automatically logged: delete launch/persona, publish, create/revoke key, create/delete/rotate webhook.

Supported Platforms

twitter, linkedin, reddit, instagram, tiktok, facebook, producthunt, hackernews, substack

Per-Platform Character Limits

Twitter 280/tweet (25,000 for X Premium) × 6 tweets (use thread array or content string), LinkedIn 3,000, Instagram 2,200, Reddit 3,000, Facebook 3,000, TikTok 4,000, Product Hunt 500, Hacker News 2,000, Substack 3,000

Core Workflow: Create & Publish

1. Check connected platforms

# User's OAuth connections
curl -s https://api.dropspace.dev/connections \
  -H "Authorization: Bearer $DROPSPACE_API_KEY"

# Official Dropspace accounts available for posting
curl -s https://api.dropspace.dev/dropspace/status \
  -H "Authorization: Bearer $DROPSPACE_API_KEY"

Connections: OAuth-connected accounts with platform, username, account_type, is_active, expires_at. Managed via dashboard. Dropspace status: Shows which official Dropspace accounts (facebook, linkedin, twitter, reddit, instagram, tiktok) are connected and available for the dropspace_platforms field.

2. Create a launch (AI generates platform-specific content)

curl -s -X POST https://api.dropspace.dev/launches \
  -H "Authorization: Bearer $DROPSPACE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "launch title",
    "product_description": "what to post about (1-2000 chars)",
    "platforms": ["twitter", "linkedin", "reddit"],
    "product_url": "https://optional-url.com",
    "persona_id": "optional-uuid",
    "scheduled_date": "optional ISO 8601 (≥15 min future)",
    "publish": "optional boolean — immediately publish after creation (returns 202, mutually exclusive with scheduled_date, requires write+publish scopes)",
    "wait": "optional boolean — wait for publishing to complete and return post URLs inline (requires publish: true, returns 200 with posting_status)",
    "dropspace_platforms": ["twitter"],
    "user_platform_accounts": {"twitter": "account-id"},
    "media": [
      {"source": "url", "url": "https://example.com/image.png"},
      {"source": "base64", "data": "iVBOR...", "filename": "slide.png", "mime_type": "image/png"}
    ],
    "media_attach_platforms": ["twitter", "linkedin"],
    "media_mode": "images|video",
    "generate_ai_videos": ["instagram", "tiktok"],
    "custom_content": "single text for all platforms (validated against lowest char limit)",
    "custom_content_reddit_title": "reddit title when using custom_content (max 300 chars)",
    "platform_contents": {
      "twitter": {"thread": ["tweet 1", "tweet 2", "tweet 3"]},
      "reddit": {"title": "...", "content": "..."},
      "linkedin": {"content": "custom post"},
      "tiktok": {
        "content": "caption text",
        "tiktok_settings": {
          "privacy_level": "PUBLIC_TO_EVERYONE",
          "auto_add_music": true,
          "allow_comments": true,
          "allow_duet": true,
          "allow_stitch": true
        }
      }
    }
  }'

Content auto-generated via Claude from description + scraped URL + persona.

Content options (mutually exclusive):

• Omit both → full AI generation for all platforms
• platform_contents → per-platform custom content. Platforms without content get AI-generated. Reddit requires title. Product Hunt/HN support optional title (max 60/80 chars). Twitter supports thread (string[], each ≤280 chars or ≤25,000 for X Premium, max 6 tweets) instead of content — mutually exclusive with content.
• custom_content → string distributed to all platforms (validated against most restrictive char limit), or string[] to create a Twitter thread (each ≤280 chars or ≤25,000 for X Premium, max 6) that joins with double newlines for other platforms. Array form requires Twitter in platforms. Use custom_content_reddit_title if Reddit is included.

user_platform_accounts key format:

• Simple keys: "twitter", "reddit", "instagram", "tiktok"
• LinkedIn personal: "linkedin:personal" → personal profile
• LinkedIn org: "linkedin:organization:<org_id>" → company page
• Facebook page: "facebook:page:<page_id>"
• Multiple keys allowed (e.g. post to personal + org simultaneously)

TikTok settings (platform_contents.tiktok.tiktok_settings):

• privacy_level (REQUIRED before publishing): "PUBLIC_TO_EVERYONE", "FOLLOWER_OF_CREATOR", "MUTUAL_FOLLOW_FRIENDS", or "SELF_ONLY"
• Optional booleans: allow_comments, allow_duet, allow_stitch, is_commercial, is_your_brand, is_branded_content, auto_add_music
• Branded content (is_branded_content: true) cannot use SELF_ONLY privacy
• Can be set at creation or updated via PATCH (deep-merged)

Inline media upload (media field): Upload images/videos inline via URL or base64 — server handles storage upload and populates media_assets in the response. Max 10 items (9 images + 1 video). Images: jpeg/png/webp/gif (5MB). Videos: mp4/mov (512MB via URL, 4MB via base64). media_attach_platforms and media_mode auto-inferred if not set. Mutually exclusive with media_assets.

Pre-uploaded media (media_assets field): For files already in storage — requires id, url, type, filename, size, mime_type. Mutually exclusive with media.

Media limits: Instagram/Facebook 10, Reddit 20, TikTok 35.

Inline publish (publish + wait fields):

• publish: true → immediately publish after creation (returns 202). Mutually exclusive with scheduled_date. Requires both write and publish scopes.
• wait: true (requires publish: true) → wait for publishing to complete synchronously and return 200 with posting_status containing per-platform results and post URLs. Typical wait: 10-30s for text platforms, up to 60s+ with Instagram/TikTok.
• If publish validation fails after creation, returns 201 with publish_error: { code, message } — retry via POST /launches/:id/publish.

Publish validation (LAUNCH_007): When publishing fails validation, the response includes a details array listing all blocking issues. Checks include: char limits (all platforms), Reddit title ≤300 chars, Reddit video needs video+thumbnail, Reddit images need images, Instagram reel needs video, Instagram carousel needs ≥2 images, TikTok requires tiktok_settings.privacy_level, TikTok video needs video, TikTok photo needs images. Instagram requires media. TikTok requires video or photos. generate_ai_videos: subset of ["instagram", "tiktok"] — generates video scripts and starts async rendering. media_mode: "images" or "video" (auto-inferred when using media).

Upload errors: UPLOAD_001 (unsupported type), UPLOAD_002 (too large), UPLOAD_003 (storage upload failed).

3. Review & edit content

# Edit specific platform content:
curl -s -X PATCH https://api.dropspace.dev/launches/LAUNCH_ID \
  -H "Authorization: Bearer $DROPSPACE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"platform_contents": {"twitter": {"thread": ["tweet 1", "tweet 2", "tweet 3"]}}}'

# Or regenerate for specific platforms:
curl -s -X POST https://api.dropspace.dev/launches/LAUNCH_ID/generate-content \
  -H "Authorization: Bearer $DROPSPACE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"platforms": ["twitter"], "generate_video_scripts": ["instagram"]}'

4. Publish

curl -s -X POST https://api.dropspace.dev/launches/LAUNCH_ID/publish \
  -H "Authorization: Bearer $DROPSPACE_API_KEY"

Returns 202. Async — poll /status or use webhooks (launch.completed, launch.failed, launch.partial).

5. Check posting status

curl -s https://api.dropspace.dev/launches/LAUNCH_ID/status \
  -H "Authorization: Bearer $DROPSPACE_API_KEY"

Returns per-platform posting logs with status, post_url, post_id, error_message, error_code, attempt_count, posted_at.

6. Get per-post analytics with engagement metrics

curl -s https://api.dropspace.dev/launches/LAUNCH_ID/analytics \
  -H "Authorization: Bearer $DROPSPACE_API_KEY"

Returns per-platform metrics (live refresh — fetches from platform APIs when stale >5 min):

• Twitter: likes, retweets, replies, quotes, bookmarks, impressions, urlClicks, profileClicks
• LinkedIn: impressions, uniqueImpressions, likes, comments, shares, clicks, engagement
• Facebook: reactions, comments, shares
• Instagram: views, engagement, saved, likes, comments, shares
• Reddit: score, upvotes, upvoteRatio, comments
• TikTok: views, likes, comments, shares

Response includes fetched_at, next_refresh_at (fetched_at + 5 min), and per-platform cache_status (fresh | refreshed | stale). Calling the endpoint triggers a refresh automatically when data is stale.

Batch Analytics

# Fetch analytics for up to 100 launches in one request
curl -s "https://api.dropspace.dev/launches/analytics?ids=uuid1,uuid2,uuid3" \
  -H "Authorization: Bearer $DROPSPACE_API_KEY"

Returns { data: [...], errors: [...] } with partial success support. Each item includes launch_id, platforms (with per-platform metrics + deletion info), and status. No fetched_at/next_refresh_at (those are single-launch only). Uses cached metrics — does not trigger live refresh from platforms.

Post Deletion Detection

Analytics responses include deletion detection fields per platform:

• is_deleted (boolean) — true if the post was detected as deleted/removed
• deleted_detected_at (ISO 8601) — when deletion was first detected
• deletion_reason — one of: not_found (404), gone (410), creator_deleted, moderation_removed, account_deleted, spam_filtered

Platform-specific detection:

• LinkedIn: Detects REMOVED_BY_LINKEDIN_TAKEDOWN
• Reddit: Checks removed_by_category
• Twitter: Catches authorization errors as possible account deletion
• TikTok/Instagram/Facebook: Detects 404/410 responses

Deletion is detected during the analytics cron refresh cycle (runs every 5 minutes for recently active posts).

First-Touch Attribution (Built-in)

Dropspace has built-in signup attribution via Next.js middleware → httpOnly cookie → profiles table.

How it works:

1. First page visit → middleware captures referrer + UTM params into ds_attr cookie (30-day expiry)
2. On signup → auth callback writes to profiles.signup_referrer, signup_utm_source, signup_utm_medium, signup_utm_campaign

Add UTM params to links:

https://www.dropspace.dev?utm_source=tiktok&utm_medium=social&utm_campaign=slideshow_feb

Query attribution data via Supabase:

SELECT signup_referrer, signup_utm_source, signup_utm_medium, signup_utm_campaign, created_at
FROM profiles
WHERE created_at >= now() - interval '7 days'
AND signup_utm_source IS NOT NULL;

Launch Management

Launch Status Lifecycle

Statuses in lifecycle order: draft → manual → trigger → scheduled → running → completed / partial / failed / cancelled

Key rules:

• The publish cron only picks up scheduled launches with scheduled_date ≤ now. All other statuses require manual action.
• Status is auto-derived on PATCH for editable launches (draft/manual/trigger/scheduled). The server overrides your requested status based on configuration:
  • Has user_platform_accounts or dropspace_platforms + scheduled_date → scheduled
  • Has user_platform_accounts or dropspace_platforms + no scheduled_date → trigger
  • Has content + no posting accounts → manual
  • This means you cannot force manual on a launch that has posting accounts. It will auto-transition to trigger.
• To unschedule without losing settings: PATCH with {"scheduled_date": null}. The server will auto-set status to trigger (since posting accounts exist). Do NOT set to draft (loses dashboard action buttons) or DELETE (soft-deletes, hard to recover).
• To pause a scheduled launch: PATCH {"scheduled_date": null}. Status becomes trigger automatically.
• POST /launches/:id/publish triggers immediate publishing regardless of scheduled_date. Never call this on scheduled launches unless you want them published now.
• manual = no posting accounts configured (publish manually). trigger = has posting accounts but no schedule (publish on demand).

PATCH fields: name (1-200 chars), scheduled_date (ISO 8601 | null to unschedule), status, platforms, product_description (max 10,000 chars), product_url (empty string to clear), persona_id (null to clear), platform_contents (deep-merged per platform — existing platforms preserved, within a platform included fields replace old values), user_platform_accounts, dropspace_platforms, media/media_assets (replaces entirely), media_attach_platforms, media_mode. All optional but ≥1 required. Running launch can only be cancelled. TikTok tiktok_settings is deep-merged (can update individual fields without overwriting others).
