Postifys by Foldious - Publish to Multiple Social Platforms Through One API

Postifys by Foldious is the unified social media publishing API at postifys.com for Facebook, Instagram, YouTube, Pinterest, LinkedIn, and TikTok - via dashboard, REST API, or n8n - not a consumer content calendar.

TikTok supports approved Direct Post for automatic publishing, plus optional Draft Upload when a creator wants to finish editing in TikTok. LinkedIn targets member profiles. Capabilities depend on account type and granted permissions.

n8n Integration

Automate with the Official n8n Community Node

Manage multi-channel social posting nodes directly inside your workflows. Postifys acts as a centralized tokens gateway, shielding your n8n pipelines from token refresh expirations.

Installation CLI 
npm install n8n-nodes-postifys
View on npm Workflow templates Open n8n Setup Guide
Verified n8n Capabilities
  • Live Asset Dropdowns: Fetches pages and channels in real-time.
  • Media URL Proxy: Automatically downloads large Google Drive/Dropbox files to local servers when required by platform APIs.
  • Normalized Responses: All platforms return identical JSON structures to simplify downstream logical branching in n8n.
Developer API

Built for backend services, CRMs, and AI Agents.

Developers can bypass implementing OAuth refresh loops and media file chunking rules. Set up a secure Postifys account, generate an API key, and handle publishing calls via unified REST endpoints.

FAQ

Frequently Asked Questions

Answers to common product, billing, and developer integration queries.

Postifys by Foldious is a unified social media publishing platform for teams, developers, and automation builders. It provides a dashboard, REST API, and n8n community node for publishing to supported social networks.

Postifys supports connected Facebook Pages, Instagram professional accounts, YouTube channels, Pinterest boards, LinkedIn member accounts, and TikTok creator accounts. Exact capabilities depend on the account type, platform approval, permissions, media format, and each network's publishing rules.

Yes. Postifys gives developers one authenticated publishing service, while each platform still keeps its own endpoint requirements for target account, caption, media, privacy, title, and publishing method.

Yes. Install the n8n-nodes-postifys community node in a compatible self-hosted n8n instance, add a Postifys API key, and build workflows that publish to connected social accounts.

Yes. Any trusted server-side automation tool that can send HTTP requests can call the Postifys REST API with an API key. Keep API keys out of browsers and public client-side code.

Users connect social accounts through OAuth, then create Postifys API keys for trusted automations. API keys can be sent as a Bearer token or X-API-Key header, depending on the endpoint.

No. Social accounts are connected once inside Postifys. Workflows then use a Postifys API key and select from the connected accounts or channels available to that user.

Postifys refreshes supported OAuth tokens when possible and shows reconnect status when a platform revokes access, a refresh token expires, permissions change, or an account password/security event invalidates the connection.

Yes, approved TikTok Direct Post can publish automatically after processing. TikTok Draft Upload is also available when a creator wants to finish editing or confirming the post inside TikTok.

Yes. Postifys supports Meta publishing workflows for connected Facebook Pages and Instagram professional accounts, including supported video and Reels-style publishing where the connected account and permissions allow it.

Yes. Connected YouTube channels can receive video uploads through Postifys. YouTube still performs its own processing after the upload is submitted.

Postifys currently targets connected LinkedIn member accounts. Company Page support should be checked against the current integration status before planning a production workflow around it.

Use public, downloadable HTTPS media URLs or supported uploaded media. Private URLs, localhost URLs, internal IPs, and other private network locations are blocked for security and SSRF protection.

That failure means the media URL points to a private, local, internal, or otherwise unsafe location. Upload the media to a public HTTPS URL or use Postifys internal media handling before retrying.

Postifys records publishing status, failure reason, queue stage, retry count, and retry-safe details where available. Failed jobs can be reviewed and retried after the underlying media, permission, token, or platform issue is corrected.

Postifys supports outbound webhook configuration for automation and monitoring use cases. Webhooks help external systems react to publishing outcomes without polling post history continuously.

Postifys applies authentication and publishing rate limits to protect live services and platform connections. Exact limits can depend on plan, endpoint, queue state, platform requirements, and abuse-prevention settings.

Postifys starts with a 7-day free trial. Card required. The trial includes 1 seat, then pricing is $2 per seat/month. One seat includes one account/profile on each supported platform.

Yes. Postifys is designed for agencies, automation teams, and developers managing multiple connected profiles, repeatable workflows, and publishing status visibility across client or brand accounts.

Postifys focuses on developer and automation workflows: REST API access, n8n integration, connected-account publishing, and operational visibility. Traditional content calendars may be better for manual editorial planning; Postifys is strongest when publishing needs to be triggered by software.

Connect once. Publish from every workflow.

Create your Postifys workspace, connect a social profile, and send your first publishing job through the API or n8n.
