Detailed Instructions and Tips

• To add a new workflow, click “Add First Step” and select the “Trigger Manually” node.
• For the AI model, select “Basic Allol M Chain” from the “Advanced AI” section.
• To obtain a Grok API key:
  • Visit grok.com or console.grok.com.
  • Sign in and click on “Create API Key”.
  • Name the key (e.g., “N8N”) and submit.
  • Copy the API key to the credentials in N8N.
• To set up the LLM model, select the llama 3.1 70 billion parameter model.
• Define prompts directly or use “Chat input” from a previous node.
• Use “Set” nodes to simulate test data.
• For sentiment analysis, instruct the AI to determine if a review is positive, negative, or neutral.
• Use the “Structured Output Parser” to ensure consistent output formats.
• To expose workflows as an API, use webhook nodes and test with tools like Postman.
• Use Merge nodes to combine data from different sources.
• Route data based on sentiment using IF or SWITCH nodes.
• Write data to Airtable by setting up Airtable nodes for each sentiment category.

URLs and Endpoints

• Grok API key acquisition: grok.com or console.grok.com
