Don't make your users wait; let your system "listen" instead of "asking."
In modern API design, speed is everything. If your backend is still "polling" for data updates, you are likely wasting server resources and creating a laggy experience for your end-users.
The Problem with Polling
Polling is like a child in a car asking, "Are we there yet?" every five seconds.
It forces your server to make constant, unnecessary requests to see if a data point is ready. This creates "noise" in your logs and can lead to rate-limiting issues and increased latency.
The Efficiency of Webhooks
Webhooks turn the conversation around.
Instead of your backend asking for updates, Smile API "pushes" a notification to your webhook endpoint the moment the data is ready. This is Step 6 of our data flow, and it is the key to a snappier, more responsive UI.
Why Webhooks Win:
- Real-Time Updates: Your app reacts the millisecond data is available.
- Resource Efficiency: No wasted CPU cycles or bandwidth on empty requests.
- Better UX: Users see their "Verified" status update instantly without refreshing.
Implementing a Real-Time Flow
To build a world-class fintech app, you need an event-driven architecture.
By leveraging Webhook best practices, you ensure that your backend stays synchronized with the Smile API platform without the overhead of traditional polling methods.
Efficiency isn't just about saving server costs; it's about providing a seamless experience. Switching from polling to webhooks is one of the easiest ways to make your application feel faster and more professional.
