Frequently asked questions
Getting Started
Product Basics
Do you use official API's for each platform?
Yes. We only use each platform’s official APIs (Google, TikTok, Facebook, etc.)—no scraping or workarounds. Mallary is a Meta Verified Tech Provider and has passed platform security reviews where required. We’re also a registered LLC based in Lexington, Kentucky, USA.
Do I need to create developer apps for each platform?
No! That's one of the biggest benefits of using Mallary. You don't need to create developer apps, wait for approval, or deal with quota limits. We handle all of that for you, so you can start posting immediately.
Can I integrate Mallary with automation tools like n8n, Zapier, Make or OpenClaw?
Yes! Mallary has an official n8n community node and works seamlessly with Zapier, Make, and other automation platforms. You can also use webhooks for custom integrations. Learn more in our Developer Docs and try our MCP Server or CLI for AI agents like OpenClaw.
What happens when a social platform changes its API or rules?
We monitor all platform changes and API updates closely. When platforms make changes, we update our integrations immediately so your workflows continue working without interruption. You don't have to worry about keeping up with constant platform changes.
Can I migrate from another social media tool to Mallary?
Yes! Whether you're migrating from Buffer, Hootsuite, or another tool, or even from custom scripts, you can easily transition to Mallary. Simply connect your social profiles and start using Mallary's API or dashboard. Your existing accounts and content remain intact.
Can I post to all my social media accounts from my phone?
Yes! The Mallary dashboard is fully responsive and works on all mobile, tablet and desktop devices. You can post to everywhere (all your socials) from anywhere (the beach). If you're controlling your OpenClaw AI Agent from Telegram on your phone, ask your agent to "install the Mallary skill".
Publishing
Scheduling, Posting, And Analytics
How reliable is scheduling?
Mallary automatically ensures posts go out as scheduled. We handle all the edge cases and platform-specific quirks so your posts are retried automatically and only mark known permanent failures as non-retryable.
Can I track analytics for posts sent through Mallary?
Yes! Once you connect your social accounts to Mallary and make a post, you can track views, comments and likes. We provide hourly refreshes for posts less than 24 hours old, and refresh less frequently as the posts get older.
Can I schedule videos?
Yes. Video scheduling is live for Instagram, Facebook, LinkedIn, YouTube, TikTok and X where supported by the connected account.
Do you auto-retry failed posts?
Yes. We automatically retry most transient failures up to 3 total attempts (initial try + retries) with exponential backoff (default starts at ~5 minutes, then increases). We also track retry state (attempt, attempts_allowed, next_retry_at) so you can see exactly what’s happening.
Do you retry every error?
No. We mark known permanent failures as non-retryable and fail fast (for example: missing required permissions/scopes, unsupported media combinations, missing required platform targets, certain 4xx auth/app-limit errors).
How do you prevent duplicate posts on retries?
For most platforms, we persist publish state per job and return success if the post already has a remote ID. This is implemented for Facebook/Meta, Instagram, LinkedIn, YouTube, TikTok, Pinterest, Reddit, and Threads. LinkedIn also uses an explicit API idempotency key (X-RestLi-Idempotency-Key) tied to the job.
Do you validate platform-specific media rules before publish?
Yes. We enforce platform/format rules (examples: max image/video counts, no image+video mixing where disallowed, duration limits, and required media for platforms like YouTube/TikTok/Pinterest).
Do you support preflight checks before posting?
Yes. We support preflight checks that verify token health, key scope requirements, and required platform options (like Pinterest board, Reddit subreddit, LinkedIn author selection) before publish.
Do you refresh expired tokens automatically?
Yes. We refresh tokens before posting where supported (Meta/Facebook, X, LinkedIn, YouTube/Google, TikTok, Pinterest, Reddit, Threads).
Can a scheduled post be deleted/canceled?
Yes, but only before processing starts. If a job is already active/completed, deletion is blocked to avoid inconsistent or partial publish states.
Engagement
Comments And AI Replies
What is the “Comments Under Post” feature?
It lets you attach up to 3 follow-up comments to a post at publish time, so the post and comments go out in one flow. If a platform or post format doesn’t support follow-up comments, we skip it. Learn more
Which platforms support comments under posts?
Comments Under Post is currently supported on Facebook feed posts, Instagram feed/reels/carousels, LinkedIn, YouTube, Pinterest, Threads, X (Twitter), and Reddit. It is not supported on TikTok or story-style formats like Facebook Stories, Instagram Stories, or Snapchat posts.
Do scheduled posts support comments under post?
Yes. For supported platform/format combinations, your follow-up comments are stored with the scheduled post and posted after the main post goes live.
What are AI Auto Replies?
AI Auto Replies automatically detect new questions and comments on your published posts and uses OpenAI (ChatGPT) to post helpful replies using the information you enter in the settings section of the Mallary dashboard. AI Auto Replies are supported on YouTube, Facebook, Instagram, LinkedIn, X (Twitter), Reddit.
How fast do AI Auto Replies happen?
Replies are near-real-time, depending on platform API limits and queue load.
Can I turn AI Auto Replies off?
Yes. You can enable or disable them in dashboard settings (and per post if enabled for your plan).
Does it reply to every comment?
It replies to supported comment types on supported platforms. We skip duplicates and avoid re-processing comments already handled. Replies use your business/brand settings and context to stay on-brand and concise.
What if a platform blocks comment posting?
We log the failure, surface it in status/observability, and continue processing other supported platforms.
Developer Tools
API, MCP, And CLI
Are there rate limits?
Yes, Rate limits are applied per user, per minute, across the API/MCP/CLI. This keeps the platform fast and stable for everyone. Find out more from our API Docs.
What is MCP in Mallary?
MCP lets you use Mallary from AI clients/agents (not just the dashboard or REST API) using a standard tool interface. You can create upload URLs, create posts, check job status, list/delete posts, view analytics, manage webhooks, and disconnect platforms.
Where is the MCP endpoint?
https://mallary.ai/mcp
How do I authenticate to MCP?
Sign-up to Mallary, visit the dashboard and grab your API key. Use it as a bearer token: Authorization: Bearer <your_api_key>
Do plan limits and rate limits still apply in MCP?
Yes. The same account permissions, plan gates, and API limits apply to MCP requests.
What is the Mallary CLI?
The Mallary CLI is the official command-line interface for Mallary. It lets you upload media, create and schedule posts, check job status, fetch analytics, manage webhooks, update settings, and disconnect platforms directly from your terminal. You can install it from npm or use it with npx. Learn more about the social media CLI.
How do I authenticate to the Mallary CLI?
Set your Mallary API key as an environment variable and the CLI will use it for authenticated commands: MALLARY_API_KEY=<your_api_key>. The CLI uses the same API key as the Mallary dashboard, API, and MCP.
Can I use the Mallary CLI in scripts, CI, or AI agents?
Yes. The CLI is built for automation. It supports human-readable terminal output by default and --json output for scripts, CI pipelines, and AI agents. That makes it a good fit for OpenClaw, cron jobs, GitHub Actions, internal tools, and terminal-based agent workflows.
Does the CLI support local file uploads and platform-specific post options?
Yes. The CLI can upload local media files to Mallary’s CDN automatically before publishing, and it also supports advanced per-platform payloads in JSON file mode for options like Instagram post types, YouTube visibility, Pinterest board IDs, and Reddit subreddits.
Do plan limits and permissions still apply in the Mallary CLI?
Yes. The CLI uses the same account, plan, and feature rules as the rest of Mallary. Rate limits, posting limits, analytics access, scheduling access, AI auto-reply plan gates, and other permissions still apply when you use the CLI.
