# Extract doctor stamp details from images with AWS Bedrock Claude and SNS

> Quick overview This workflow receives a webhook request, fetches a doctor stamp/pad image from a separate file-management workflow, uses AWS Bedrock (Claude) vision OCR to extract structured doctor and facility details, and publishes the base64-encoded result to an AWS SNS topic, with matching SNS-based error notifications. How it works 1. Receives a POST request via a webhook and immediately returns a JSON acknowledgement containing the execution and workflow IDs. 2. Calls a separate n8n workflow to fetch the source document image from file management based on the webhook payload. 3. Resizes the image to a maximum of 800×800 pixels to standardize input and reduce payload size. 4. Sends the image to an AWS Bedrock Claude vision chat model through an AI Agent that is instructed to strictly extract only clearly visible doctor and facility details and output valid JSON. 5. Builds a success response that includes the extracted JSON plus the incoming executionRequestId and queryId. 6. Base6
