n8n is an open-source, self-hosted workflow automation platform that gives you complete control over your data and pipelines. When you combine n8n with the Dohoo API, you can build powerful, fully custom automation workflows — from AI-generated content all the way to published posts on Instagram, YouTube, TikTok, and beyond — without any manual intervention.

​
Why n8n + Dohoo

  • Full control — host n8n on your own infrastructure and keep your API keys and media files entirely within your environment.
  • Flexible triggers — kick off a workflow on a schedule, a webhook event, a new file in cloud storage, or any other supported trigger.
  • No vendor lock-in — everything runs through standard HTTP requests against the Dohoo REST API, so your workflow is portable.

​
Authentication

Every request to the Dohoo API must include your API key in the X-API-Key header. In n8n, add this header to each HTTP Request node. 
X-API-Key: api_xxxxxxxxxxxxxxxxxxxxxxxx
Store your API key in n8n’s built-in Credentials manager (Generic Credential → Header Auth) rather than hardcoding it directly in a node. This keeps your key out of the workflow JSON and makes rotation straightforward.

​
Basic workflow pattern

A typical n8n workflow for publishing to a social platform follows four steps:
1

Trigger

Start the workflow with any n8n trigger — a Schedule node for time-based publishing, a Webhook node to respond to external events, or a cloud-storage node (e.g., Google Drive) to react when a new file is uploaded.
2

Get a presigned upload URL

Add an HTTP Request node that sends a POST request to /api/upload/presigned-url. Dohoo responds with a presigned S3 URL and a fileId you’ll use in the next steps.
{
  "method": "POST",
  "url": "https://dohoo.ai/api/upload/presigned-url",
  "headers": {
    "X-API-Key": "api_xxxxxxxxxxxxxxxxxxxxxxxx"
  }
}
3

Upload your file to S3

Add a second HTTP Request node that sends a PUT request to the uploadUrl returned in step 2. Attach your binary file as the request body. No X-API-Key header is needed for the S3 presigned URL — it’s self-authenticating.
4

Publish to your social platform

Add a final HTTP Request node that posts to the relevant Dohoo publish endpoint. Pass the fileId from step 2, your connectionId, and any platform-specific metadata such as a caption or title.

​
Example: publish to Instagram

Here is a complete configuration for the publish step of an Instagram workflow: 
{
  "method": "POST",
  "url": "https://dohoo.ai/api/v2/instagram/publish",
  "headers": {
    "X-API-Key": "api_xxxxxxxxxxxxxxxxxxxxxxxx"
  },
  "body": {
    "fileId": "your-file-id",
    "connectionId": "your-connection-id",
    "caption": "Your post caption #hashtag"
  }
}
Replace your-file-id with the ID returned by the presigned-URL step, and your-connection-id with the ID of your connected Instagram account (In the social media tab, your connection ID will appear to the right of the account you’re looking for).
