--- title: "Social Media Platform APIs — All 16 | IndReelForge" description: "Every network IndReelForge posts to — Instagram, YouTube, TikTok, LinkedIn, X, Reddit, Discord and more — with content types, caption limits and setup." url: https://indreelforge.com/platforms --- # Social media posting API for 16 platforms IndReelForge publishes videos, photos and text to every network below through one REST endpoint. Connect each account once to a profile, then send a single request with the platforms you want — the same call works from the dashboard, the JavaScript and Python SDKs, n8n, Make, Zapier or an AI agent over MCP.

Limits shown above come from each platform's own API and are checked before upload, so a file that a network would reject fails fast with a clear error.
