Short answer: Zapier is fine for low–mid volume CI/CD notifications — it cuts maintenance and speeds integrations but can be costly, introduces latency, and has limits on complex logic and data controls. Recommendation: use Zapier for Slack routing and non-critical workflows, and implement custom Lambdas or a small webhook service for high-throughput, security-sensitive, or incident-creation paths.
