API-Driven Data Integration
Webhooks, polling, and event-driven architecture for keeping systems in sync.
Databases aren't the only source of truth anymore. Your payment data lives in Stripe. Your email engagement lives in SendGrid. Your user analytics live in Mixpanel. Your CRM data lives in HubSpot. Each of these systems has its own database that you can't access directly — but they all offer APIs.
API-driven integration is how modern applications keep these external systems synchronized with your own database. Instead of ETL batches running overnight, you're responding to events in near-real-time as they happen across your ecosystem.
Get this right and your systems are always in sync. Get it wrong and you've got phantom customers, missing payments, and data that contradicts itself across platforms.
