Webhook Promo Scheduler

webhook-promo-scheduler

Schedule and send promo/alert messages to a Discord webhook URL with an anti-spam ledger.

What it does

• Posts to a Discord webhook (JSON payload with content)
• Maintains a JSONL ledger to enforce max 1 successful post per day per channel
• Provides a rotation mode that cycles through a message list
• Supports --dry-run so you can validate cadence/ledger without sending anything

Positioning (best angle)

• Ship updates without becoming a spammer (or leaking a webhook): strict cadence + audit trail.

Files

• scripts/post_webhook.py : Discord webhook POST helper (stdlib only)
• scripts/ledger.py : JSONL ledger helpers (stdlib only)
• scripts/promo_scheduler.py : CLI tool (stdlib only)

Ledger

• Default: ~/.openclaw/webhook-promo-ledger.jsonl
• Override: --ledger-path /path/to/ledger.jsonl
• JSONL fields (per line): date, channel, status, hash

Safety

• The CLI refuses to print the webhook URL.
• Logs redact any webhook URL if it would appear.
• Recommended: keep the webhook in a private channel, rotate it if leaked, and use --dry-run before enabling live sends.
