How it works / What it does
1. Trigger – Manually run the workflow. 2. Edit Fields (manual) – Provide inputs: - targetUrl (e.g., an Amazon category/search/listing page) - deviceType (desktop | mobile | tablet) - Optional: maxItems, notes, reportTitle, reportOwner 3. Scraper API Request (HTTP Request → POST) Calls Decodo Scraper API with: - URL to crawl, headless JS enabled - Device emulation (UA + viewport) - Optional waitFor / executeJS to ensure late-loading content is captured 4. HTML Response Parser (Code/Function or HTML node) Pulls the HTML string from Decodo response and normalizes it (strip scripts/styles, collapse whitespace). 5. Product Analyzer Agent (LLM + Structured Output Parser) Prompts an LLM to extract structured “book” objects from the HTML: The Structured Output Parser enforces a strict JSON schema and drops malformed items. 6. Build 📚 Book Purchase Report (Code/LLM) Converts the JSON array into a Markdown (or HTML) report with: - Executive summary (top picks, average price/rating) - Table of items (rank, title, author, price, rating, link) - “Recommended to buy” shortlist (rules configurable) - Notes / owner / timestamp 7. Configure Google Drive Folder (manual) Choose/create a Drive folder for output artifacts. 8. Create Document File (Google Docs API) Creates a Doc from the generated Markdown/HTML. 9. Convert Document to PDF (Google Drive export) Exports the Doc to PDF. 10. Upload report to Slack Sends the PDF (and/or Doc link) to a chosen Slack channel with a short summary.
