Connect Obsidian and n8n with the Post Webhook Plugin

Built with n8n
1

Hi everyone!

I’m thrilled to share something new for the part of the n8n community that also uses the note‑taking app Obsidian. I’ve developed a plugin called Post Webhook that bridges the gap between these two powerful tools, allowing you to seamlessly integrate your Obsidian notes into your n8n workflows.

With Post Webhook, you can send the full content of your notes, including structured YAML frontmatter metadata and attachments, directly to any Webhook-compatible endpoint. This means you can take the information stored in your notes and immediately put it to work in your automated n8n workflows.

To give you a sense of what’s possible, I’ve created an example n8n workflow template (Send Emails via Obsidian) that makes it easy to send emails directly from your Obsidian notes. Using the Post Webhook plugin, the n8n workflow takes note content and parses YAML frontmatter to define key email fields like recipients and subject lines. It even processes attachments, encoding them for emails and sending them seamlessly through Gmail. Once the email is sent, the workflow confirms the status back to your note, so you always have a complete record.

Feedback, ideas, and suggestions are always welcome.

Thank you for this. I am still trying to figure out how to use it, but this seems very interesting. I am trying to create a workflow where i can integrate my Web Clippings, send them to Obsidian and then to n8n to post to a Google Sheet where I can then write a blog post, track prices of items, or just maintain a record of something. I will let you know if i get it working. It would also be interesting if there ways a way to send a web hook directly from the clipping, but I should probably figure out the basics first.

Hi Keithc,

Thank you for your comment. The idea you’ve outlined is indeed perfectly achievable.

For example, imagine your Webclipper Obsidian note looks like this:

Using your Post Webhook plugin, you can send this note to an n8n Post Webhook with a workflow like this:

Here’s a brief explanation of how this workflow processes the note content:

  • Webhook: Captures the note data from Obsidian via the Post Webhook plugin.
  • Separate Attachment Data: Extracts attachment details from the incoming payload.
  • Fix Base64 String: Cleans and decodes any Base64-encoded data in the note.
  • Process Each Attachment: Prepares to handle multiple attachments in batches.
  • Convert Attachment to File: Converts attachment data into file format for processing.
  • Upload Attachments to Google Drive: Saves the attachments to a specific folder in Google Drive.
  • Aggregate Links to Attachments: Collects links to the uploaded attachments into a single array.
  • Prepare Data for Sheet: Maps metadata (e.g., title, author, tags) and attachment links to structured fields.
  • Append Row to Sheet: Adds the note’s metadata and attachment links as a new row in a Google Sheets document.

The result will look like this:

This assumes that the notes are sent manually to the webhook. You may also be able to use another plugin to monitor a folder and automatically execute the command ‘send note to webhook.’

Please let me know if you’d like to receive the JSON file for this workflow!

Como conectarías obsidian, es decir, enviar un mensaje a un agente solicitando que te haga una nota con una estructura especifica y que te la ponga en obsidian
