}Notes by Grok:
Node Types: I used n8n's built-in node types (e.g., webhook, httpRequest, googleDrive, function, if) to match the actions in the flowchart. You may need to adjust the exact parameters or credentials based on your setup.
Credentials: Placeholder API keys and refresh tokens are included (e.g., your-api-key). Replace these with actual credentials.
Positions: Approximate position values are set to reflect the layout in the image, but you can adjust them in the n8n UI.
Connections: The connections object defines the flow between nodes, following the sequence in the image.
Required APIs: The workflow assumes the use of Reddit Post Render API and Replicate API, which are integrated via HTTP requests. You’ll need to configure these APIs with valid endpoints and keys.
