PostWireGuides: post to every network from wherever you work
Each guide answers one question in its first two sentences, then gives steps that work with PostWire today — the dashboard's real buttons, the REST fields, the MCP tools and the n8n node's fields. Live networks: TikTok, Instagram, YouTube, LinkedIn (personal profiles), Facebook Pages, Bluesky, Mastodon, Telegram and Discord.
Creators and small businesses
- How to post the same video to TikTok, Instagram Reels and YouTube Shorts at once
TikTok, Instagram and YouTube don't cross-post to each other, so you upload the vertical video once to a tool that publishes through each network's official API. - A tool that writes a different caption for each social network from one idea
PostWire takes one idea and writes a separate, native post for each network you tick — a hook-first TikTok caption, a short Instagram caption, a YouTube title with description and tags, a first-person LinkedIn post, a Bluesky post under 300 characters — then publishes or schedules them. - Repurpose.io alternative: upload once, get a caption written for each network
If you want to upload a short video once and publish it to TikTok, Instagram Reels and YouTube Shorts with a different caption on each, PostWire does that from $0 (free for one business, TikTok included). - Post to multiple social media accounts at once

Claude, ChatGPT and AI agents
- Can Claude post to LinkedIn and Instagram for you? Yes — with a connector
Claude can't post to LinkedIn or Instagram on its own, but it can through a connector that uses each network's official API. - How to schedule social media posts with Claude
Claude schedules social posts through a connector: add PostWire from Claude's connector directory, connect your networks, then say "schedule this for Friday at 9:00 my time". - How to post to TikTok from ChatGPT
ChatGPT has no built-in TikTok posting; it needs a connector (an MCP server) that holds TikTok's Direct Post approval. - An MCP server that uploads one video to TikTok and YouTube Shorts
PostWire's hosted MCP server (https://postwire.io/api/mcp) lets Claude, Cursor or any MCP client publish one video to TikTok, YouTube (Shorts) and Instagram (Reels) through those networks' approved APIs. - PostWire in Claude

n8n and Make
- How to post to TikTok, Instagram and YouTube from n8n
n8n has no core node that publishes to TikTok, so you call a posting API that already holds TikTok's Direct Post approval. - How to post to Instagram from n8n
Posting to Instagram from n8n with Meta's Graph API means your own Meta app, App Review, a container per media item and a wait for video processing; a posting API does those steps for you. - How to post a video to TikTok from Make.com
Make's own TikTok app lists campaign and ads modules plus a generic API call, but no module that publishes a video (checked on apps.make.com on Oct 1, 2026), and calling TikTok's API yourself needs a TikTok app that passed TikTok's audit. - n8n social media automation

Developers
- How to use TikTok's Direct Post API without doing your own app audit
You can't make public Direct Posts with your own TikTok app until TikTok audits it: unaudited clients may only post SELF_ONLY (private), for up to 5 users in 24 hours, whose accounts must be private (TikTok's Content Sharing Guidelines, read Oct 1, 2026). - The cheapest social media posting APIs with a real free tier
Four posting APIs had a free tier on Oct 1, 2026: PostWire (1 business, every live network including TikTok, 30 posts a month), Zernio (2 connected accounts, full API), Buffer (3 channels, 1 API key, 3,000 requests a month) and Upload-Post (2 profiles, 10 uploads a month, no TikTok). - PostWire API reference
