How APIs Use Webhooks to Push Data in Real Time
from The API Podcast with Fexingo: REST, GraphQL, and Modern Web APIs Hosted by Fexingo
In this special 150th episode, Lucas and Luna explore the world of webhooks: how they flip the API relationship from polling to pushing, and why that matters for real-time updates. They walk through a concrete example—a payment provider notifying a merchant's system the moment a transaction is authorized—and break down the anatomy of a webhook call, including payloads, signatures, and retry policies. The hosts compare webhooks to REST polling and GraphQL subscriptions, discuss delivery guarantees and idempotency, and share practical advice on handling failures gracefully. They also touch on security best practices like HMAC signatures and constant-time comparison. Whether you're building your first integration or debugging a flaky webhook, this episode gives you a clear mental model and actionable takeaways. Plus, Lucas and Luna acknowledge how listener support keeps the show ad-free. Tune in for a deep but accessible conversation that will change how you think about API communication. #Webhooks #RealTimeAPIs #APIIntegration #EventDrivenArchitecture #PaymentAPIs #HMAC #Idempotency #RetryPolicy #PayloadSigning #GraphQLSubscriptions #RESTPolling #DeveloperTools #APISecurity #TechPodcast #Technology #FexingoBusiness #BusinessPodcast #SoftwareEngineering Keep every episode free: buymeacoffee.com/fexingo
