n8n Workflow: AI-Powered Content Generation (Incomplete)
This n8n workflow appears to be a foundational structure for an AI-powered content generation system, likely intended for social media or similar applications. While the provided JSON is incomplete, it outlines the initial steps of receiving a chat message, processing it with OpenAI, and then conditionally handling the output.
Important Note: The provided JSON is only a partial definition of a workflow. It includes a trigger, an AI processing step, and conditional logic, but lacks the subsequent actions (e.g., posting to social media, generating reels) that would complete the described purpose in the directory name. This README describes what is present in the JSON.
What it does (based on available JSON):
- Listens for Chat Messages: The workflow is triggered by an incoming chat message.
- Processes with OpenAI: The received chat message is sent to OpenAI for processing, likely to generate a response, content ideas, or initial drafts.
- Conditional Logic: It then uses an "If" node to evaluate the output from OpenAI, suggesting different paths based on the AI's response.
- Wait (Conditional Path): One of the conditional paths leads to a "Wait" node, indicating a potential delay before further processing.
Prerequisites/Requirements:
- n8n Instance: A running instance of n8n.
- OpenAI API Key: An API key for OpenAI to utilize its language models.
- Chat Trigger Integration: Configuration for the "Chat Trigger" node, which implies integration with a chat platform (e.g., Telegram, Slack, Discord) where messages will be received.
Setup/Usage:
- Import the Workflow: Import the provided JSON into your n8n instance.
- Configure Credentials:
- OpenAI: Set up your OpenAI credential with your API key.
- Chat Trigger: Configure the "Chat Trigger" node to connect to your desired chat platform and listen for incoming messages.
- Complete the Workflow: As the provided JSON is incomplete, you will need to add further nodes to define what happens after the OpenAI processing and conditional logic. This would typically involve:
- Nodes to generate images/videos (e.g., Google Veo 3 AI, if integrated).
- Nodes to publish content to social media platforms.
- Nodes for data storage or further content refinement.
- Activate the Workflow: Once configured and completed, activate the workflow to start listening for chat messages.

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.
