Frequently asked questions

What is the PostEverywhere API?
The PostEverywhere API is a REST API that lets you programmatically schedule and publish social media posts across 8 platforms (Instagram, X, LinkedIn, Facebook, TikTok, YouTube, Threads), upload media, manage connected accounts, and monitor publishing results — all from a single integration.
How do I get an API key?
Go to Settings > Developer in the PostEverywhere dashboard. Click "Create API Key", name your key, select scopes (Read, Write, and/or AI), and copy the key. It starts with pe_live_ and should be stored securely.
Is the API included in my plan?
Yes. API access is included on all PostEverywhere plans — Starter ($19/mo), Growth ($39/mo), and Pro ($79/mo). There is no separate API add-on or enterprise-only gating. View full pricing.
Which platforms does the API support?
The API supports all 8 platforms available in PostEverywhere: Instagram (posts, Reels, Stories, carousels), X (tweets, threads), LinkedIn (profiles, company pages), Facebook (pages, Reels), TikTok (videos), YouTube (videos, Shorts), and Threads (text, images).
Can I post to multiple platforms at once?
Yes. When creating a post via POST /posts, pass multiple account IDs in the account_ids array. The API publishes to all specified platforms simultaneously from a single request.
What are the rate limits?
API requests are rate-limited to 60 per minute, 1,000 per hour, and 10,000 per day. Rate limit headers (X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset, Retry-After) are included in every response.
Do you have official SDKs?
We provide an official Node.js SDK (npm install posteverywhere), a Claude Code MCP integration (@posteverywhere/mcp), and code examples in cURL. The API follows REST conventions and works with any HTTP client in any language.
Is there a sandbox or test mode?
Currently, the API operates in production mode. We recommend creating a test organization with sandbox social accounts for development. All API keys can be revoked instantly from Settings > Developer if needed.
Can I use the API to build a white-label scheduler?
Yes. Many agencies use the PostEverywhere API to build custom-branded scheduling tools for their clients. The API handles all platform authentication, media processing, and publishing — you build the UI. See our agency solutions for more details.
How does AI image generation work via the API?
Send a POST request to /ai/generate-image with a text prompt. The API uses our AI image generator to create visuals and saves them to your media library. Pair it with the AI content generator for fully automated posts. Each generation uses 1 AI credit from your plan allowance.
Can I automate posting from my CMS or blog?
Yes. Use the POST /posts endpoint to auto-publish content whenever your CMS publishes. Common integrations include WordPress webhooks, Ghost, and Contentful. You can also use RSS-to-post workflows with tools like n8n or Zapier connected to our API. Learn more about social media automation.
What happens if a post fails on one platform?
The API publishes to each platform independently. If Instagram succeeds but TikTok fails (e.g., token expired), you get per-platform results showing exactly which destinations succeeded and which failed. Use POST /posts/{id}/retry to retry only the failed destinations without re-publishing to platforms that already succeeded.
