Create the following credentials:\n\n   * **NewsAPI (Query Auth)** — from [https://newsapi.org](https://newsapi.org)\n   * **Google Gemini (PaLM API)** — use your Gemini API key\n   * **Replicate (Bearer Auth)** — API key from [https://replicate.com/account](https://replicate.com/account)\n   * **Supabase (Header Auth)** — endpoint to your `/functions/v1/blog-api` (set your key in header)\n   * **Slack API** — create a Slack App token with `chat:write` permission\n3. Edit the **NewsAPI URL** query parameter to match your industry (e.g., `q=AI automation SaaS`).\n4. Update the **Supabase publish URL** to your project endpoint if needed.\n5. Adjust the **Slack Channel** name under “Slack Notification”.\n6. (Optional) Change the **Schedule Trigger** time as per your timezone.\n\n---\n\n### **💡 Notes & Tips**\n\n* The **Code in JavaScript** node is robust against malformed or extra text in Gemini output — it sanitizes Markdown and reconstructs clean JSON safely.\n* You can replace Supabase with any CMS or Webhook endpoint by editing the “Publish to Supabase” node.\n* The Replicate model used is `ideogram-ai/ideogram-v3-turbo` — you can swap it with Stable Diffusion or another model for different aesthetics.\n* Use the `slug` field in your blog URLs for SEO-friendly links.\n* Test with one manual execution before activating scheduled runs.\n* If Slack notification fails, verify the token scopes and channel permissions.\n\n"
