Handle GDPR data deletion requests with Slack
This workflow automatically deletes user data from different apps/services when a specific slash command is issued in Slack. Watch this talk and demo to learn more about this use case. The demo uses Slack, but Mattermost is Slack-compatible, so you can also connect Mattermost in this workflow. Prerequisites Accounts and credentials for the apps/services you want to use. Some basic knowledge of JavaScript. Nodes Webhook node triggers the workflow when a Slack slash command is issued. IF nodes confirm Slack's verification token and verify that the data has the expected format. Set node simplifies the payload. Switch node chooses the correct path for the operation to perform. Respond to Webhook nodes send responses back to Slack. Execute Workflow nodes call sub-workflows tailored to deleting data from each individual service. Function node, Crypto node, and Airtable node generate and store a log entry containing a hash value. HTTP Request node sends the final response back to Slack.

This workflow automates the conversion of 2D images into high-quality 3D models (.glb format) by integrating Google Sheets with the Hunyuan3D v2 model on Fal.ai. It handles the entire pipeline—from fetching image URLs to polling for completion and saving the final asset—eliminating manual modeling time for artists and developers. How it works This template operates on a schedule to process images in batches or individually: Data Retrieval: The workflow fetches new rows from a Google Sheet where the RESULT_GLB column is empty. AI Generation: It sends the IMAGE_URL to the Hunyuan3D v2 API on Fal.ai to initiate the 3D generation process. Status Polling: The workflow automatically enters a loop, checking the job status every 30 seconds until the model is marked "COMPLETED." Result Update: Once finished, it retrieves the download link for the .glb file and writes it back to the specific row in your Google Sheet. Use Cases Game Development: Rapidly create prototype props and assets from concept art. E-commerce: Convert product photos into 3D models for web viewers. AR/VR: Generate background assets for immersive environments from simple 2D inputs. Setup steps Google Sheet: Create a new sheet with two header columns: IMAGEURL and RESULTGLB. Add the images you want to convert in the first column. Fal.ai Credentials: Sign up at Fal.ai and generate an API Key. In n8n, create a Header Auth credential with the name Authorization and value Key YOURAPIKEY. Configure Nodes: Update the Get new image and Update Result nodes to select your specific Google Sheet. Ensure the HTTP Request nodes are using your Fal.ai Header Auth credential.
