If you're building a crypto payment application, you'll eventually face an important question:
Should you rely on REST APIs, Webhooks, or both?
The answer is almost always both.
REST APIs
REST APIs allow your application to:
Create payment requests
Generate invoices
Check transaction status
Retrieve wallet balances
Manage customer payments
They're perfect for requesting information whenever your application needs it.
Webhooks
Webhooks notify your application automatically when something changes.
Typical webhook events include:
Payment detected
Transaction confirmed
Payment completed
Payment expired
Withdrawal processed
Instead of constantly polling an API, your server receives updates instantly.
Why You Need Both
A production-ready crypto payment system usually combines the strengths of both approaches.
REST APIs are ideal for creating and managing resources, while webhooks ensure your application reacts to blockchain events in real time.
Best Practices
Verify webhook signatures.
Make webhook handlers idempotent.
Log every incoming event.
Retry failed webhook processing.
Always validate blockchain confirmations.
Conclusion
Whether you're building an eCommerce platform, SaaS product, or crypto marketplace, combining REST APIs with secure webhook handling creates a much more reliable payment experience.
