Agent pitfalls & tips
- NLA API is designed for AI agents — pass natural language instructions.
- Each action must be manually 'exposed' by the user in Zapier dashboard.
- Preview before execute: POST /exposed/{id}/execute/ with preview_only:true.
- Connected accounts are pre-configured — the agent doesn't need individual service auth.
- For traditional automation, use Zap webhooks (POST to webhook URL) instead of NLA.
