Issue with Integrating Payment Gateways in my SaaS Application

[Katherine_Ryan]

I've heard that payment gateways often use webhooks to notify the application about payment updates and changes in subscription statuses. Could someone explain how to properly set up webhook handlers and ensure the reliability of receiving these events? Payments can sometimes fail for various reasons. What's the recommended way to handle payment failures gracefully within the application? Are there specific error codes or responses that I should be prepared to handle?

Is this a SAS software-related question? Software as a Service(SaaS) is not the same as SAS software.
