Breaking: publish_to → restrict_publish_to

• Clearer name for platform targeting — the optional post field publish_to is now restrict_publish_to on create, update, schedule, and publish, and in responses. The name makes the behavior obvious: omit it or set it to null to publish to ALL connected platforms; provide a list (e.g. ["instagram", "facebook"]) to restrict to just those.
• Action required — the old publish_to key is no longer accepted; sending it returns a 422 naming the unknown field. Rename it to restrict_publish_to in your requests, and read restrict_publish_to from responses. (It briefly shipped as an accepted alias; that alias is now removed.)

​

Rate limits

• Daily and weekly limits added — alongside the existing 100 requests/minute, each API key now also has a 2,000 requests/day and 10,000 requests/week limit. These are generous for normal automation (a weekly batch of 10 posts uses ~20 requests). A 429 response names the specific window you hit, and the X-RateLimit-* and Retry-After headers tell you when to retry. See Errors for header details.

​

Breaking changes

• Business-scoped endpoints are now nested under the business — endpoints that operate on a single business now live under /api/businesses/{business_id}/... (for example POST /api/businesses/{business_id}/posts, GET /api/businesses/{business_id}/topics, POST /api/businesses/{business_id}/media). The business_id moves out of the JSON body and query string and into the URL path. Org-level endpoints (/api/businesses, /api/keys, /api/webhooks, /api/feedback, /api/health) are unchanged.

​

New features

• Publish a post immediately — POST /api/businesses/{business_id}/posts/{post_id}/publish fires the publish flow in the background and returns the post right away. Poll GET /businesses/{business_id}/posts/{post_id} for the final status. Optional publish_to body restricts the publish to a subset of connected platforms.
• List integrations on a business — GET /api/businesses/{business_id}/integrations returns the connected social accounts (platform, username, page, status). Use the id field as the integration_id in stats endpoints.
• List posts on a connected platform — GET /api/businesses/{business_id}/integrations/{integration_id}/posts lists posts on the connected account (Marky-posted or otherwise) with stats. Supports cursor-based pagination. Covers all 7 platforms.
• Per-post stats — all platforms — GET /api/businesses/{business_id}/posts/{post_id}/stats returns per-platform metrics for a post published through Marky, hydrated from your connected integrations. Covers Facebook, Instagram, LinkedIn, Twitter/X, TikTok, Pinterest, and YouTube. Stats are normalized into a consistent shape (likes, comment_count, reach, views, impressions, etc.) — no per-platform branching in your code.
• Per-integration stats — GET /api/businesses/{business_id}/integrations/{integration_id}/stats returns account metrics for a single integration. GET /api/businesses/{business_id}/integrations/{integration_id}/posts/{external_post_id}/stats returns metrics for a single post on a single platform — useful with the publish_id values from /businesses/{business_id}/integrations/{integration_id}/posts.

​

Updates

• Giphy URLs in media uploads — giphy.com is now an allowed host suffix when uploading media, so you can pass Giphy-hosted GIFs directly without re-uploading.
• Better image upload handling — Images with malformed EXIF metadata no longer fail to upload, and image generation errors now return clearer messages.
• Retry on transient errors — CRUD endpoints now automatically retry transient database errors, improving reliability for posts, businesses, topics, and media.
• Restored analytics fields — Post-count and period columns are back on business analytics views, so business summaries return complete data.

​

Bug fixes

• Fixed search fallback when looking up uploaded images — orphaned uploads are now correctly resolved.
• Plan restrictions are kept in sync when Stripe sends subscription updates, preventing stale limits after plan changes.
• Narrowed the checkout fraud block to true fraud signals so legitimate customers are no longer incorrectly blocked.
• Stripe InvalidRequestError responses are now logged with full context before being surfaced as a 400, making billing failures easier to debug.

​

Security

• Row-level security is now enforced on API keys and Canva connections, so credentials are only readable by the org that owns them.

​

New features

• Creative format selection — You can now specify a creative_formats array when creating posts to control the visual format of each post. Options include design, carousel, meme, image, gif, and video. Formats are cycled round-robin across your generated posts.
• AI image style modifiers — Marky now applies style modifiers and creative type mapping when generating AI images, producing visuals that better match the tone and format of each post.
• Reference images for video generation — Pass reference_images when generating videos to guide the visual style. Useful for maintaining brand consistency across video content.
• Audio URL for shorts — You can now provide an audio_url when generating shorts, giving you direct control over the audio track instead of relying on auto-selected music.

​

Improvements

• Canva design owner filtering — Marky now identifies the owner of imported Canva designs and surfaces a clearer error when a design is shared as view-only, so you know exactly what to fix.
• Imagery preferences in media search — Your business-level imagery preferences are now consistently applied during media selection, so generated posts better reflect your visual brand.
• Webhook reliability — Background poster generation and webhook delivery have been restored for more reliable post-publish notifications.
• Analytics accuracy — Post analytics now correctly handle posts with zero views instead of treating them as missing data.

​

Bug fixes

• Fixed thumbnail generation for deleted or inaccessible videos — the system now handles these gracefully instead of failing silently.
• Improved video URL detection to support additional formats during thumbnail extraction.
• Fixed an issue where providing a custom_idea without topics would not use the idea as the post topic.
• Corrected the post restriction period reset schedule for subscription limits.

​

New features

• First comment on publish — When a post goes live on Facebook or LinkedIn, Marky can now automatically add the post link as the first comment. Useful for driving traffic without cluttering the caption.
• Video speedup transforms — Speed up video clips during post generation. Marky applies the transform automatically when a faster pace fits the design.
• Bring Your Own Key (BYOK) for Gemini — Connect your own Google Gemini API key to generate images and videos. BYOK orgs are not charged Marky credits for AI generation in Max chat.
• Carousel video support — Video generation now works with multi-page (carousel) templates, so you can create richer video posts.
• AppSumo credit allowance — AppSumo users now receive a monthly credit allowance.

​

Improvements

• Smarter text sizing — Post designs now auto-cap character counts based on the actual box dimensions and a minimum readable font size. Overflowing CTA text is shortened automatically.
• Layout-aware copy — The LLM receives max_lines and chars_per_line constraints so generated text fits the design without overflow.
• Smart image cropping — Google Vision CROP_HINTS are used to frame subjects better across all generated images.
• Better video music — Background music volume is reduced, and the music picker uses genre-based fallback instead of random selection when no audio tags are set.
• Imagery preferences — Your business-level imagery preferences now influence the image keywords Marky generates, giving you more relevant visuals.
• Onboarding improvements — New businesses generate 15 candidate posts during onboarding and surface the best 10 (previously 10 → 3).

​

Bug fixes

• Fixed a crash caused by non-numeric letterSpacing values in post designs.
• Fixed text vertical alignment in video rendering.
• Fixed an issue where video audio tracks were not persisted when saving designs.
• Corrected media type detection — uploaded videos are no longer incorrectly tagged as images.
• Fixed empty-string UUID handling in post placeholder creation.
• Resolved an error when extracting frames from inaccessible video URLs — the API now returns an actionable error message.
• Fixed video foreground animations using an unsupported ZOOM effect.

• Clarified rate limits in the Introduction and Errors guides (100 requests per minute).
• Added this changelog with an RSS feed for integrations and automation tools.

• Org-scoped API keys (create in Organization Settings in the dashboard).
• Posts, businesses, topics, library / media, webhooks, and feedback endpoints.
