Post to every network from n8n

01

Before you start

• A Reelspan account with your networks connected to a profile. The free plan includes every network: start free.
• An API key from the dashboard (Developers → API keys). Keys can be limited to the scopes a tool needs.

02

Create an API key

In the Reelspan dashboard, open Developers → API keys and create a key. In n8n, add a Header Auth credential named Authorization with the value Bearer followed by your key.

03

Add an HTTP Request node

Method POST, URL below, Authentication: the Header Auth credential. Body: Form-Data. Add one field per line; repeat platform[] for each network. For a file from an earlier node (Google Drive, Read Binary File), set video to n8n Binary File and its input field name.

user        my-brand
platform[]  tiktok
platform[]  youtube
platform[]  instagram
video       https://example.com/clip.mp4
title       Your caption

04

Read the result

The response lists each network with its status and post URL. For long uploads send async_upload=true, keep the request_id, and check it with GET /v1/posts/status, or let a Reelspan webhook call your workflow when each network is done.

05

Ideas to build

Drive folder to every network

Google Drive Trigger (file created) → Google Drive Download → HTTP Request with the file as video.

RSS to LinkedIn, X and Bluesky

RSS Feed Trigger → HTTP Request to /v1/posts/text with the title and link.

Sheet as a content calendar

Schedule Trigger → Google Sheets (rows due today) → HTTP Request with scheduled_date from the row.

AI agent that posts

Give the AI Agent node an HTTP Request tool for /v1/posts/text, or connect it to the Reelspan MCP server.

Going further

• github.com/Reelspan/n8n-nodes-reelspan: A Reelspan community node (publish, schedule, retry, analytics, AI captions) is open source on GitHub; until it is on npm, the HTTP Request node above does the same job.
• Every field each network takes, scheduling, webhooks and errors: the docs.
• Per-network walkthroughs: upload guides. Is everything publishing right now? Status.
• Other ways in: all integrations.
