Post for multiple clients from one account: a brand per client (Oct 7, 2026)
Create one brand per client in a single PostWire account, send each client a connect link that puts their own accounts into their brand, and pick the brand when you write: the post goes only to that client's accounts.
Social media approval workflow for clients: sign-off from a link, no client login (Oct 7, 2026)
Give each client a brand in PostWire, switch on Require approval for it and add the client's email under Other approvers: every post for that client then waits, and the client gets a private link to approve it — no PostWire account, no password.
A social media tool with approvals for a small team: roles, seats and brands (Oct 7, 2026)
PostWire's Starter plan ($9 a month) gives a small team 3 seats with roles and approval rules per brand: invite people as admin, editor, contributor (every post they make waits for approval), approver or viewer, and choose which posts wait for a person before they go out.
Instagram MCP server: let Claude or any agent post to Instagram (Oct 6, 2026)
Add https://postwire.io/api/mcp to your agent as a remote MCP server, connect your Instagram Business or Creator account once, and the agent can publish a photo, a Reel or a carousel of up to 10 items with post_to_social, or queue it with schedule_post.
YouTube MCP server: let Claude or any agent upload your videos and Shorts (Oct 6, 2026)
Add https://postwire.io/api/mcp to your agent as a remote MCP server, connect your channel once with Google, and the agent uploads a video with post_to_social — or schedules it with schedule_post — with its title (up to 100 characters), description, tags and privacy: public, unlisted or private.
Use PostWire inside CoreSpeed, Composio or any MCP gateway (Oct 4, 2026)
Register https://postwire.io/api/mcp as a remote MCP server in the gateway, with OAuth, and each person signs in to their own PostWire account.
The best apps to cross-post short videos to TikTok, Reels and Shorts (Oct 3, 2026)
To cross-post one short video to TikTok, Instagram Reels and YouTube Shorts, use a scheduler that publishes to all three through their official APIs; what separates them is the price of the three networks together, whether the free plan includes TikTok, and who writes each caption.
The best n8n node to publish to TikTok, Instagram and YouTube Shorts (Oct 3, 2026)
n8n has no core node that publishes to TikTok, so the answer is a community node from a posting service.

The best apps to cross-post short videos to TikTok, Reels and Shorts
To cross-post one short video to TikTok, Instagram Reels and YouTube Shorts, use a scheduler that publishes to all three through their official APIs; what separates them is the price of the three networks together, whether the free plan includes TikTok, and who writes each caption.
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.

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.
Use PostWire inside CoreSpeed, Composio or any MCP gateway
Register https://postwire.io/api/mcp as a remote MCP server in the gateway, with OAuth, and each person signs in to their own PostWire account.
Instagram MCP server: let Claude or any agent post to Instagram
Add https://postwire.io/api/mcp to your agent as a remote MCP server, connect your Instagram Business or Creator account once, and the agent can publish a photo, a Reel or a carousel of up to 10 items with post_to_social, or queue it with schedule_post.
YouTube MCP server: let Claude or any agent upload your videos and Shorts
Add https://postwire.io/api/mcp to your agent as a remote MCP server, connect your channel once with Google, and the agent uploads a video with post_to_social — or schedules it with schedule_post — with its title (up to 100 characters), description, tags and privacy: public, unlisted or private.

n8n and Make

The best n8n node to publish to TikTok, Instagram and YouTube Shorts
n8n has no core node that publishes to TikTok, so the answer is a community node from a posting service.
How to post to TikTok, Instagram and YouTube from n8n
n8n ships a YouTube node but no built-in node for TikTok or Instagram, so publishing one video to TikTok, Instagram Reels and YouTube Shorts takes a community node: n8n-nodes-postwire does all three in a single node, through PostWire's audited TikTok, Meta and Google apps.
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.

Agencies and teams

Social media approval workflow for clients: sign-off from a link, no client login

PostWire's Starter plan ($9 a month) gives a small team 3 seats with roles and approval rules per brand: invite people as admin, editor, contributor (every post they make waits for approval), approver or viewer, and choose which posts wait for a person before they go out.
Post for multiple clients from one account: a brand per client
Create one brand per client in a single PostWire account, send each client a connect link that puts their own accounts into their brand, and pick the brand when you write: the post goes only to that client's accounts.

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 social media posting APIs have a free tier a developer can build on (read Oct 7, 2026): PostWire (1 business, every network connected including TikTok, 2 networks per post, 20 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).
