Generate LinkedIn Content Ideas with GPT-4o Mini and Gmail Delivery for Influencers

This n8n workflow automates the generation of engaging LinkedIn content ideas using the power of a large language model (LLM) and delivers them directly to your inbox via Gmail. It's designed for influencers, thought leaders, or anyone looking to streamline their content creation process for LinkedIn.

What it does

This workflow simplifies and automates the following steps:

  1. Manual Trigger: The workflow is initiated manually, allowing you to run it on demand whenever you need new content ideas.
  2. Generate Content Ideas with AI: It leverages a Basic LLM Chain, configured with an Azure OpenAI Chat Model (specifically GPT-4o Mini), to generate creative and relevant LinkedIn content ideas based on a predefined prompt.
  3. Format Output: The raw output from the AI is processed by a Code node to extract and format the content ideas into a clean, readable structure.
  4. Deliver via Email: The formatted content ideas are then sent to a specified email address using Gmail, providing you with a convenient summary of your new content inspiration.
  5. Informative Note: A Sticky Note provides additional context or instructions within the workflow itself.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running instance of n8n.
  • Azure OpenAI Account: Access to Azure OpenAI with a deployed GPT-4o Mini chat model. You will need your Azure OpenAI API Key, API Base URL, and Deployment Name.
  • Gmail Account: A configured Gmail credential in n8n to send emails.

Setup/Usage

  1. Import the Workflow:
    • Copy the provided JSON code.
    • In your n8n instance, click "New" in the top left, then "Import from JSON".
    • Paste the JSON code and click "Import".

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.
