- Migrate from Airtable to Baserow: BaserowClient with snapshots, actions, creatives, logs - Claude agents (Haiku for decisions/units, Sonnet for creatives) with cost_cap_eur vs CPL comparison - Slack bot with colored action emojis, effect text before approval buttons, 500-char justifications - Streamlit dashboard with date-range navigation, campaign drill-down (adsets/ads), Histórico tab - Approval server (FastAPI + ngrok) for Slack button callbacks - backfill.py for historical snapshot regeneration with Claude re-analysis - Margin fix: 0-lead campaigns contribute -spend (not 0) to margin - CTR fix: Meta returns CTR as percentage already, removed *100 - Parameter fix: pass decision parameter to Slack action for correct budget effect display Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

|
FastAPI server that receives Slack interactive button callbacks (Approve / Reject).
|
|
|
|
Setup:
|
|
1. Create a Slack App, enable Interactivity, set Request URL to:
|
|
https://your-domain.com/slack/actions
|
|
2. Set SLACK_SIGNING_SECRET in your .env
|
|
3. Run: uvicorn approval_server:app --host 0.0.0.0 --port 3000
|
|
(for local dev: use ngrok to expose port 3000)
