📖 About This Skill

name: postfast description: Schedule and manage social media posts across TikTok, Instagram, Facebook, X (Twitter), YouTube, LinkedIn, Threads, Bluesky, Pinterest, Telegram, and Google Business Profile using the PostFast API. Use when the user wants to schedule social media posts, manage social media content, upload media for social posting, list connected social accounts, check scheduled posts, delete scheduled posts, cross-post content to multiple platforms, manage Google Business Profile posts, or automate their social media workflow. PostFast is a SaaS tool — no self-hosting required. homepage: https://postfa.st metadata: {"openclaw":{"emoji":"⚡","primaryEnv":"POSTFAST_API_KEY","requires":{"env":["POSTFAST_API_KEY"]}}}

PostFast

Schedule social media posts across 11 platforms from one API. SaaS — no self-hosting needed.

Setup

1. Sign up at https://app.postfa.st/register (7-day free trial, no credit card) 2. Go to Workspace Settings → generate an API key 3. Set the environment variable:

   export POSTFAST_API_KEY="your-api-key"

Base URL: https://api.postfa.st Auth header: pf-api-key: $POSTFAST_API_KEY

Important: The header name is pf-api-key (not Authorization: Bearer or x-api-key). Regenerating your key in settings permanently invalidates the previous one. See Troubleshooting if you get 403 errors.

Core Workflow

1. List connected accounts

curl -s -H "pf-api-key: $POSTFAST_API_KEY" https://api.postfa.st/social-media/my-social-accounts

Returns array of { id, platform, platformUsername, displayName }. Save the id — it's the socialMediaId required for every post.

Platform values: TIKTOK, INSTAGRAM, FACEBOOK, X, YOUTUBE, LINKEDIN, THREADS, BLUESKY, PINTEREST, TELEGRAM, GOOGLE_BUSINESS_PROFILE

2. Schedule a text post (no media)

curl -X POST https://api.postfa.st/social-posts \
  -H "pf-api-key: $POSTFAST_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "posts": [{
      "content": "Your post text here",
      "mediaItems": [],
      "scheduledAt": "2026-06-15T10:00:00.000Z",
      "socialMediaId": "ACCOUNT_ID_HERE"
    }],
    "controls": {}
  }'

Returns { "postIds": ["uuid-1"] }.

3. Schedule a post with media (3-step flow)

Step A — Get signed upload URLs:

curl -X POST https://api.postfa.st/file/get-signed-upload-urls \
  -H "pf-api-key: $POSTFAST_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "contentType": "image/png", "count": 1 }'

Returns [{ "key": "image/uuid.png", "signedUrl": "https://..." }].

Step B — Upload file to S3:

curl -X PUT "SIGNED_URL_HERE" \
  -H "Content-Type: image/png" \
  --data-binary @/path/to/file.png

Step C — Create post with media key:

curl -X POST https://api.postfa.st/social-posts \
  -H "pf-api-key: $POSTFAST_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "posts": [{
      "content": "Post with image!",
      "mediaItems": [{ "key": "image/uuid.png", "type": "IMAGE", "sortOrder": 0 }],
      "scheduledAt": "2026-06-15T10:00:00.000Z",
      "socialMediaId": "ACCOUNT_ID_HERE"
    }],
    "controls": {}
  }'

For video: use contentType: "video/mp4", type: "VIDEO", key prefix video/.

4. List scheduled posts

curl -s -H "pf-api-key: $POSTFAST_API_KEY" "https://api.postfa.st/social-posts?page=0&limit=20"

Returns { "data": [...], "totalCount": 25, "pageInfo": { "page": 1, "hasNextPage": true, "perPage": 20 } }.

Query parameters:

page (int, default 0) — 0-based page index. Response shows 1-based display page in pageInfo.page

limit (int, default 20, max 50) — items per page

platforms (string) — comma-separated filter: FACEBOOK,INSTAGRAM,X

statuses (string) — comma-separated: DRAFT, SCHEDULED, PUBLISHED, FAILED

from / to (ISO 8601 UTC) — date range filter on scheduledAt

Example: GET /social-posts?page=0&limit=50&platforms=X,LINKEDIN&statuses=SCHEDULED&from=2026-06-01T00:00:00Z&to=2026-06-30T23:59:59Z

5. Delete a scheduled post

curl -X DELETE -H "pf-api-key: $POSTFAST_API_KEY" https://api.postfa.st/social-posts/POST_ID

6. Cross-post to multiple platforms

Include multiple entries in the posts array, each with a different socialMediaId. They share the same controls and mediaItems keys.

7. Generate a connect link (for clients)

Let clients connect their social accounts to your workspace without creating a PostFast account:

curl -X POST https://api.postfa.st/social-media/connect-link \
  -H "pf-api-key: $POSTFAST_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "expiryDays": 7, "sendEmail": true, "email": "client@example.com" }'

Returns { "connectUrl": "https://app.postfa.st/connect?token=..." }. Share the URL — they can connect accounts directly. Rate limit: 50/hour.

8. Create a draft post

Two unrelated concepts share the word "draft" — don't mix them up:

| What you want | How | |---------------|-----| | PostFast draft (any platform) — saved in PostFast, not scheduled, user finalizes from the dashboard | Set status: "DRAFT" and omit scheduledAt. Works for every platform. | | TikTok app draft — pushes the post to the TikTok app's draft inbox so the user finishes editing on their phone | Set controls.tiktokIsDraft: true. TikTok-only. This is not a PostFast draft state — it still needs scheduledAt. |

⚠️ Common mistake — status placement: status is a top-level field, sibling of posts and controls. It is not a per-post field. If you put it inside the post object, the API silently ignores it, defaults to SCHEDULED, and rejects the request with "All posts must have scheduledAt when status is not present, as default is SCHEDULED".

// ❌ Wrong — status nested inside the post
{ "posts": [{ "content": "...", "status": "DRAFT", "socialMediaId": "..." }] }// ✅ Right — status at top level
{ "posts": [{ "content": "...", "socialMediaId": "..." }], "status": "DRAFT", "controls": {} }

Per-post fields: content, mediaItems, socialMediaId, scheduledAt (optional for drafts), firstComment. Top-level fields: status, approvalStatus, controls.

PostFast draft (recommended for "save now, schedule later"):

curl -X POST https://api.postfa.st/social-posts \
  -H "pf-api-key: $POSTFAST_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "posts": [{ "content": "Draft idea...", "mediaItems": [], "socialMediaId": "ACCOUNT_ID" }],
    "status": "DRAFT",
    "controls": {}
  }'

See examples/draft-post.json for the platform-agnostic pattern, or examples/tiktok-app-draft.json for the TikTok-app-inbox case.

9. Get post analytics

Fetch published posts with their performance metrics:

curl -s -H "pf-api-key: $POSTFAST_API_KEY" \
  "https://api.postfa.st/social-posts/analytics?startDate=2026-03-01T00:00:00.000Z&endDate=2026-03-31T23:59:59.999Z&platforms=TIKTOK,INSTAGRAM"

Query parameters:

startDate (ISO 8601, required) — start of date range

endDate (ISO 8601, required) — end of date range

platforms (string, optional) — comma-separated filter

socialMediaIds (string, optional) — comma-separated account UUIDs

Returns { "data": [{ id, content, socialMediaId, platformPostId, publishedAt, latestMetric }] }.

latestMetric fields: impressions, reach, likes, comments, shares, totalInteractions, fetchedAt, extras. All numbers are strings (bigint). latestMetric is null if metrics haven't been fetched yet.

Supported platforms for analytics: Facebook, Instagram, Threads, LinkedIn, TikTok, YouTube, Pinterest. LinkedIn personal accounts are excluded. YouTube returns views, likes, comments, and total interactions (no reach or shares).

Pinterest specifics (requires a Pinterest business account):

Canonical fields:

impressions, likes (reactions: heart/applaud/idea/etc.), comments — lifetime totals from Pinterest's pin endpoint.

shares — 90-day rolling save count. This is the only canonical field that isn't lifetime; Pinterest's v5 API does not expose lifetime save totals.

totalInteractions — sum of pin clicks + outbound clicks + saves + reactions + comments. Mostly lifetime, but the saves portion is 90-day, so treat it as a "best available" interaction total rather than strictly lifetime.

reach — always null (Pinterest doesn't return it).

extras (lifetime):

pin_clicks — opens of the pin's close-up view

outbound_clicks — clicks to the destination URL

engagement, engagement_rate, pin_click_rate, outbound_click_rate — Pinterest's lifetime analytics fields, passed through when present

extras (90-day rolling):

impressions_90d, pin_clicks_90d, outbound_clicks_90d — same metrics as their lifetime counterparts but for the last 90 days

save_rate — saves ÷ impressions over the 90-day window

extras for video pins (when present):

video_mrc_views, video_avg_watch_time, video_v50_watch_time, video_10s_views, video_start, quartile_95_percent_view

Refresh cadence: every 6 hours for pins under 14 days old, once a day for pins 14–60 days old. You can also trigger a manual refresh from the dashboard.

Rate limit: 350/hour.

Common Patterns

Pattern 1: Cross-platform campaign

Post the same content to LinkedIn, X, and Threads at the same time:

curl -X POST https://api.postfa.st/social-posts \
  -H "pf-api-key: $POSTFAST_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "posts": [
      { "content": "Big announcement!", "mediaItems": [], "scheduledAt": "2026-06-15T09:00:00.000Z", "socialMediaId": "LINKEDIN_ID" },
      { "content": "Big announcement!", "mediaItems": [], "scheduledAt": "2026-06-15T09:00:00.000Z", "socialMediaId": "X_ID" },
      { "content": "Big announcement!", "mediaItems": [], "scheduledAt": "2026-06-15T09:00:00.000Z", "socialMediaId": "THREADS_ID" }
    ],
    "controls": {}
  }'

See examples/cross-platform-post.json for a complete example.

Pattern 2: Instagram Reel with upload

1. Get signed URL with contentType: "video/mp4" 2. PUT video to signed URL 3. Create post with instagramPublishType: "REEL"

Optional: add a custom cover image by uploading a JPEG (max 8MB) via the same 3-step flow, then set coverImageKey in the media item. You can also set coverTimestamp (milliseconds) as a fallback frame.

See examples/instagram-reel.json for the basic request, or examples/instagram-reel-cover.json for a Reel with a custom cover image.

Pattern 3: TikTok video with privacy settings

Upload video, then post with privacy controls:

# controls object:
{
  "tiktokPrivacy": "PUBLIC",
  "tiktokAllowComments": true,
  "tiktokAllowDuet": false,
  "tiktokAllowStitch": false,
  "tiktokBrandContent": true
}

See examples/tiktok-video.json.

Pattern 4: Pinterest pin (board required)

Always fetch boards first, then post:

# Step 1: Get boards
curl -s -H "pf-api-key: $POSTFAST_API_KEY" \
  https://api.postfa.st/social-media/PINTEREST_ACCOUNT_ID/pinterest-boards
Step 2: Post with board ID
controls: { "pinterestBoardId": "BOARD_ID", "pinterestLink": "https://yoursite.com" }

See examples/pinterest-pin.json.

Pattern 5: YouTube Short with tags and playlist

Upload video, then post with YouTube controls:

# controls object:
{
  "youtubeIsShort": true,
  "youtubeTitle": "Quick Tip: Batch Your Content",
  "youtubePrivacy": "PUBLIC",
  "youtubePlaylistId": "PLxxxxxx",
  "youtubeTags": ["tips", "productivity", "social media"],
  "youtubeMadeForKids": false
}

See examples/youtube-short.json.

Pattern 5b: YouTube video with custom thumbnail

Upload both video and thumbnail image, then reference the thumbnail key in controls:

# 1. Upload thumbnail image (separate from video upload)
curl -X POST https://api.postfa.st/file/get-signed-upload-urls \
  -H "pf-api-key: $POSTFAST_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "contentType": "image/jpeg", "count": 1 }'
PUT thumbnail to signed URL
2. Upload video (same 3-step flow as always)
3. Create post with thumbnail key in controls:
{
  "youtubeIsShort": false,
  "youtubeTitle": "Full Tutorial: Social Media Strategy",
  "youtubePrivacy": "PUBLIC",
  "youtubeThumbnailKey": "image/abc123.jpg",
  "youtubeTags": ["tutorial", "social media"],
  "youtubeMadeForKids": false
}

Thumbnail specs: JPEG/PNG recommended, max 2MB, 1280x720 (16:9), min width 640px. Requires phone-verified YouTube channel. If thumbnail upload fails, the video still publishes without the custom thumbnail.

See examples/youtube-video-thumbnail.json.

Pattern 6: Google Business Profile post

Always fetch locations first, then post with GBP-specific controls:

# Step 1: Get locations
curl -s -H "pf-api-key: $POSTFAST_API_KEY" \
  https://api.postfa.st/social-media/GBP_ACCOUNT_ID/gbp-locations
Step 2: Create a standard post with CTA
controls: { "gbpLocationId": "accounts/.../locations/...", "gbpTopicType": "STANDARD", "gbpCallToActionType": "LEARN_MORE", "gbpCallToActionUrl": "https://yoursite.com" }

Three post types: STANDARD (updates), EVENT (time-bound), OFFER (deals with coupons). EVENT and OFFER require gbpEventTitle, gbpEventStartDate, gbpEventEndDate.

See examples/gbp-standard.json, examples/gbp-event.json, and examples/gbp-offer.json.

Pattern 7: LinkedIn document post

Documents (PDF, PPTX, DOCX) display as swipeable carousels on LinkedIn.

1. Get signed URL with contentType: "application/pdf" 2. PUT the file to signed URL 3. Create post using linkedinAttachmentKey instead of mediaItems

# controls: { "linkedinAttachmentKey": "file/uuid.pdf", "linkedinAttachmentTitle": "Q1 Marketing Playbook" }
Note: mediaItems should be [] when using linkedinAttachmentKey

See examples/linkedin-document.json.

Pattern 8: First comment (auto-posted after publish)

Add a firstComment to any post — it's auto-posted ~10 seconds after the main post goes live (up to 3 retries):

{
  "posts": [{ "content": "Main post text", "firstComment": "Link: https://postfa.st", "mediaItems": [], "scheduledAt": "...", "socialMediaId": "X_ID" }],
  "controls": {}
}

Supported on: X, Instagram, Facebook, YouTube, Threads. NOT supported on: TikTok, Pinterest, Bluesky, LinkedIn.

See examples/x-first-comment.json.

Pattern 9: X (Twitter) retweet

Schedule a retweet — content and media are ignored:

{
  "posts": [{ "content": "", "scheduledAt": "...", "socialMediaId": "X_ID" }],
  "controls": { "xRetweetUrl": "https://x.com/username/status/1234567890" }
}

See examples/x-retweet.json.

Pattern 10: Batch scheduling (a week of posts)

Schedule multiple posts at different times in a single API call (up to 15 posts per request):

See examples/batch-scheduling.json.

Platform-Specific Controls

Pass these in the controls object. See references/platform-controls.md for full details.

| Platform | Key Controls | |---|---| | TikTok | tiktokPrivacy, tiktokAllowComments, tiktokAllowDuet, tiktokAllowStitch, tiktokIsDraft, tiktokIsAigc, tiktokBrandOrganic, tiktokBrandContent, tiktokAutoAddMusic | | Instagram | instagramPublishType (TIMELINE/STORY/REEL), instagramPostToGrid, instagramCollaborators, instagramTrialReelStrategy | | Facebook | facebookContentType (POST/REEL/STORY), facebookReelsCollaborators | | YouTube | youtubeIsShort, youtubeTitle, youtubePrivacy, youtubePlaylistId, youtubeTags, youtubeMadeForKids, youtubeCategoryId, youtubeThumbnailKey | | LinkedIn | linkedinAttachmentKey, linkedinAttachmentTitle (for document posts) | | X (Twitter) | xRetweetUrl (retweet) | | Pinterest | pinterestBoardId (required), pinterestLink | | Google Business Profile | gbpLocationId (required), gbpTopicType, gbpCallToActionType, gbpCallToActionUrl, gbpEventTitle, gbpEventStartDate, gbpEventEndDate, gbpOfferCouponCode, gbpOfferRedeemUrl, gbpOfferTerms | | Bluesky | No platform-specific controls — text + images only | | Threads | No platform-specific controls — text + images/video | | Telegram | No platform-specific controls — text + images/video/mixed media |

Helper Endpoints

Pinterest boards: GET /social-media/{id}/pinterest-boards → returns [{ boardId, name }]

YouTube playlists: GET /social-media/{id}/youtube-playlists → returns [{ playlistId, title }]

GBP locations: GET /social-media/{id}/gbp-locations → returns [{ id, locationId, title, address, mapsUri }]. Use locationId as gbpLocationId in controls

Connect link: POST /social-media/connect-link → returns { connectUrl }. Let clients connect accounts without a PostFast account. Params: expiryDays (1-30, default 7), sendEmail (bool), email (required if sendEmail=true)

Rate Limits

Global (per API key): 60/min, 150/5min, 300/hour, 2000/day

Per-endpoint:

POST /social-posts: 350/day

GET /social-posts: 200/hour

GET /social-posts/analytics: 350/hour

POST /social-media/connect-link: 50/hour

Platform limits:

X (Twitter) via API: 5 posts per account per day — do not exceed this

Check X-RateLimit-Remaining-* headers. 429 = rate limited, check Retry-After-* header. For batch operations, add a 1-second delay between API calls.

Media Specs Quick Reference

| Platform | Images | Video | Carousel | |---|---|---|---| | TikTok | Carousels only | ≤250MB, MP4/MOV, 3s-10min | 2-35 images | | Instagram | JPEG/PNG | ≤1GB, 3-90s (Reels) | Up to 10 | | Facebook | ≤30MB, JPG/PNG | 1 per post | Up to 10 images | | YouTube | — | Shorts ≤3min, H.264 | — | | LinkedIn | Up to 9 | ≤10min | Up to 9, or documents (PDF/PPTX/DOCX) | | X (Twitter) | Up to 4 | — | — | | Pinterest | 2:3 ratio ideal | Supported | 2-5 images | | Google Business Profile | 1 image (JPEG/PNG, 5MB max) | Not supported | — | | Bluesky | Up to 4 | Not supported | — | | Threads | Supported | Supported | Up to 10 | | Telegram | Up to 10 | Supported | Up to 10 mixed media |

Common Gotchas

1. Always fetch accounts first — socialMediaId is a UUID, not a platform name. Call GET /social-media/my-social-accounts to get valid IDs. 2. Media MUST go through 3-step upload — No external URLs. Always: get signed URL → PUT to S3 → use the key in mediaItems. 3. scheduledAt must be in the future — ISO 8601 UTC format. Past dates return 400. 4. Pinterest ALWAYS requires pinterestBoardId — Fetch boards first with GET /social-media/{id}/pinterest-boards. 5. TikTok requires video for standard posts — Images only work in carousels (2-35 images). 6. LinkedIn documents use linkedinAttachmentKey — NOT mediaItems. Set mediaItems: [] when posting documents. 7. Content-Type on S3 PUT must match — The Content-Type header in your S3 PUT must match what you requested in get-signed-upload-urls. 8. Instagram Reels need video 3-90 seconds — Outside this range returns an error. 9. YouTube Shorts need video under 3 minutes — H.264 codec with AAC audio recommended. 10. X (Twitter) has a 280 character limit — Longer content is silently truncated. 11. Cross-posting shares controls — The controls object applies to ALL posts in the batch. Platform-irrelevant controls are ignored. 12. X (Twitter) API limit is 5 posts/account/day — Exceeding this risks account restrictions. 13. firstComment only works on 5 platforms — X, Instagram, Facebook, YouTube, Threads. TikTok, Pinterest, Bluesky, LinkedIn return a validation error. 14. Retweets ignore content/media — When xRetweetUrl is set, the content and mediaItems fields are ignored. 15. LinkedIn documents support PDF, DOC, DOCX, PPT, PPTX — Max 60MB. Cannot mix with regular media. 16. Pagination is 0-based — page=0 returns the first page. Response pageInfo.page shows 1-based display number. 17. Instagram trial reels require instagramPublishType: "REEL" — Setting instagramTrialReelStrategy without it returns 400. Also cannot be combined with instagramCollaborators. 18. YouTube custom thumbnails require phone verification — youtubeThumbnailKey only works if the YouTube channel is phone-verified. If it fails, the video still publishes without the custom thumbnail. 19. GBP ALWAYS requires gbpLocationId — Fetch locations first with GET /social-media/{id}/gbp-locations. Use the locationId field (not id). 20. GBP supports only 1 image — No video, no carousels. JPEG/PNG, max 5MB. 21. GBP EVENT/OFFER posts require dates — gbpEventStartDate and gbpEventEndDate are required when gbpTopicType is EVENT or OFFER. 22. GBP content limit is 1,500 characters — Shorter than most platforms. 23. GBP posts expire — Standard posts auto-expire after 6 months. Event/Offer posts expire at their end date. 24. coverTimestamp is milliseconds — e.g., "5000" = 5 seconds into the video. Not seconds. 25. coverImageKey platform limits — Instagram Reels: JPEG only, max 8MB. Facebook Reels: any format, max 10MB. Pinterest video: JPEG/PNG. NOT supported on TikTok (use coverTimestamp) or YouTube (use youtubeThumbnailKey). 26. Facebook Reels don't support coverTimestamp — Only coverImageKey works for FB Reel covers. coverTimestamp is ignored.

Troubleshooting

403 "Missing organizationId or activeWorkspaceId"

This is the most common error. It means the API didn't recognize your key. Check these in order:

1. Wrong header name. The header must be exactly pf-api-key. Not Authorization: Bearer, not x-api-key, not api-key. Example:

   # Correct
   curl -H "pf-api-key: YOUR_KEY_HERE" https://api.postfa.st/social-media/my-social-accounts   # Wrong — these all return 403
   curl -H "Authorization: Bearer YOUR_KEY_HERE" ...
   curl -H "x-api-key: YOUR_KEY_HERE" ...

2. Env var not set. If $POSTFAST_API_KEY isn't set in your shell, the literal string $POSTFAST_API_KEY gets sent as the key value. Verify it's set:

   echo $POSTFAST_API_KEY    # Should print a 44-character base64 string ending with "="

If empty, re-export it. If you're using a .env file, make sure your tool actually loads it (dotenv, direnv, etc.). Shell quoting matters: use double quotes around the value if it contains special characters.

3. Regenerated key. Each time you click "Generate API Key" in PostFast settings, the previous key is permanently invalidated. Only regenerate if the old key is compromised. If you regenerated and are still using the old key, that's why it fails.

4. Wrong key entirely. Your PostFast API key is a 44-character base64 string ending with =. Don't confuse it with keys from other services (OpenAI sk-proj-..., Stripe sk_live_..., etc.).

401 Invalid or missing API key

The pf-api-key header is either missing from the request or the value is empty. Double-check that your HTTP client is actually sending the header (some tools strip custom headers on redirects).

429 Rate limit exceeded

You've hit the per-workspace rate limit. Check the Retry-After-Minute, Retry-After-5Minutes, Retry-After-Hour, or Retry-After-Day response header for when you can retry. Limits: 60/min, 150/5min, 300/hour, 2,000/day.

Tips for the Agent

Always call my-social-accounts first to get valid socialMediaId values.

For media posts, complete the full 3-step upload flow (signed URL → S3 PUT → create post).

scheduledAt must be ISO 8601 UTC and in the future.

Pinterest always requires pinterestBoardId — fetch boards first.

LinkedIn documents use linkedinAttachmentKey instead of mediaItems.

For carousels, include multiple items in mediaItems with sequential sortOrder.

Video cover images: use coverImageKey in mediaItems for IG Reels, FB Reels, Pinterest video. Use coverTimestamp (milliseconds) for TikTok. YouTube uses youtubeThumbnailKey in controls.

When cross-posting, adjust content length for each platform's limits (X: 280, Bluesky: 300, TikTok: 2200, GBP: 1500).

If the user doesn't specify a time, suggest tomorrow at 9:00 AM in their timezone.

Batch up to 15 posts per API call for efficiency.

Use firstComment for CTAs and links — keeps the main post clean and gets better engagement.

X (Twitter) allows only 5 posts per account per day via API — warn the user if they're batching many X posts.

For draft posts, set status: "DRAFT" and omit scheduledAt — the user can finalize in the PostFast dashboard.

GBP always requires gbpLocationId — fetch locations first with GET /social-media/{id}/gbp-locations.

GBP supports 3 post types: STANDARD (default), EVENT, and OFFER. EVENT/OFFER need start and end dates.

GBP only supports 1 image (no video, no carousels) and has a 5-post/day limit.

Use GET /social-posts with from/to filters to check what's already scheduled before adding more.
