Most SKY API tutorials get you to "hello world"—this session picks up where the documentation ends. We'll walk through the hard lessons learned building a production multi-tenant application on top of the SKY API, including authentication patterns that don't break at 3am, handling rate limits gracefully, webhook reliability, and architecting for multiple schools without multiplying your infrastructure costs. Key takeaways: - Token refresh strategies for long-lived multi-tenant integrations - Patterns for handling SKY API rate limits and failures without data loss - How to structure your integration so adding a new school is a configuration change, not a code change - Monitoring and alerting patterns so you know when your integration breaks before your schools do
