This workflow digests mentions of n8n on Reddit that can be sent as an single email or Slack summary each week. We use OpenAI to classify if a specific Reddit post is really about n8n or not, and then the summarise it into a bullet point sentence.

How it works

  1. Get posts from Reddit that might be about n8n;
  2. Filter for the most relevant posts (posted in last 7 days and more than 5 upvotes and is original content);
  3. Check if the post is actually about n8n;
  4. If it is, categorise with OpenAI.

Bear in mind: Workflow only considers first 500 characters of each reddit post. So if n8n is mentioned after this amount, it won't register as being a post about n8n.io.

Next steps

  • Improve OpenAI Summary node prompt to return cleaner summaries;
  • Extend to more platforms/sources - e.g. it would be really cool to monitor larger Slack communities in this way;
  • Do some classification on type of user to highlight users likely to be in our ICP;
  • Separate a list of data sources (reddit, twitter, slack, discord etc.), extract messages from there and have them go to a sub workflow for classification and summarisation.

n8n Reddit AI Digest Workflow

This n8n workflow automates the process of fetching posts from a specified Reddit subreddit, filtering them, summarizing them using OpenAI, and then merging the summaries. This allows you to create a curated digest of Reddit content.

What it does

This workflow performs the following steps:

  1. Manual Trigger: The workflow is initiated manually, allowing you to run it on demand.
  2. Reddit Post Fetching: Connects to the Reddit API to retrieve posts from a configured subreddit.
  3. Filtering (If Node): Applies a conditional filter to the Reddit posts. The exact filtering logic is defined within the "If" node.
  4. OpenAI Summarization: For posts that pass the filter, it sends the content to OpenAI to generate a summary.
  5. Edit Fields (Set Node): Modifies or adds fields to the data, likely to format the summarized content or add additional metadata.
  6. Merge Summaries: Combines the processed (and potentially summarized) data from different paths of the workflow, likely bringing together filtered and unfiltered content, or different types of processed content.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running instance of n8n.
  • Reddit Account & API Credentials: To fetch posts from Reddit. You'll need to set up a Reddit OAuth2 credential in n8n.
  • OpenAI API Key: To utilize the summarization capabilities of OpenAI. You'll need to set up an OpenAI API credential in n8n.

Setup/Usage

  1. Import the workflow: Download the provided JSON and import it into your n8n instance.
  2. Configure Credentials:
    • Set up your Reddit OAuth2 credential for the "Reddit" node.
    • Set up your OpenAI API Key credential for the "OpenAI" node.
  3. Customize Reddit Node:
    • Specify the Subreddit you want to monitor.
    • Adjust other parameters like Limit or Timeframe as needed.
  4. Customize If Node:
    • Define your desired filtering logic within the "If" node to select which Reddit posts should be processed.
  5. Customize OpenAI Node:
    • Adjust the Model and Prompt for summarization as per your requirements.
  6. Customize Edit Fields (Set Node):
    • Modify the fields being set or transformed to match your desired output format for the digest.
  7. Activate the workflow: Once configured, activate the workflow.
  8. Execute Manually: Click "Execute workflow" on the "Manual Trigger" node to run the workflow.

This workflow provides a flexible foundation for creating AI-powered digests of Reddit content, which can be further extended to post to Slack, Discord, email, or other platforms using additional n8n nodes.

Key settings: pricebook2Id (hardcoded in script): e.g., 01sxxxxxxxxxxxxxxx Source lines: $('Message a model').first().json.message.content.products Output: { soql, codes } --- 8) Query PricebookEntries (Salesforce) Purpose: Fetch PricebookEntry.Id for each Product2.ProductCode. Key settings: Resource: search Query: ={{ $json.soql }} Creds: salesforceOAuth2Api Output: Items with Id, Product2.ProductCode (used for mapping). --- 9) Code in JavaScript (Build OLI payloads) Purpose: Join lines with PBE results and Opportunity Id ➜ build OpportunityLineItem payloads. Inputs: OpportunityId: ={{ $('Create an opportunity').first().json.id }} Lines: ={{ $('Message a model').first().json.message.content.products }} PBE rows: from previous node items Output: { body: { allOrNone:false, records:[{ OpportunityLineItem... }] } } Notes: Converts discount_total ➜ per-unit if needed (currently commented for standard pricing). Throws on missing PBE mapping or empty lines. --- 10) Create Opportunity Line Items (HTTP Request) Purpose: Bulk create OLIs via Salesforce Composite API.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
