Monitor failed payments for your PHP application

These days, many PHP applications are served via a subscription model where users pay a monthly or yearly fee to use the application. These applications are called SaaS or Software as a Service application. In these applications, users are usually charged a recurring monthly or yearly fee, or in some cases, a pay-as-you-go model where they are charged depending on their usage of the said PHP application.

In either of these models, a common issue that the developers of the PHP application usually face is when a user's payment fails. These commonly occur when the user's credit card information is invalid, when the user's credit card has expired, or when the user's credit card has been declined by the bank. In addition, in some cases, users use one-time credit cards only valid for a single payment and not recurring payments.

Whether the payment failure is intentional or unintentional, it can cause significant issues for the PHP application and the user. For example, if the user is heavily dependent on the application and their payment fails, they may not be able to use it. As a result, they may be forced to cancel their subscription, commonly called churn. In addition, if the payment failure is unintentional, the user may not be aware of the issue and may not be able to use the application until they resolve it.

Therefore, tracking and monitoring failed payments in your PHP application is essential to ensure that the user is aware of the issue and can resolve it before it causes any significant problems. Fortunately, here at LogSnag, we have created a powerful solution for this problem. LogSnag is a powerful, real-time event tracking tool that works seamlessly with any PHP application. With LogSnag, you can set up event tracking for anything you want and track when a user's payment fails in your PHP application in real time. You may also set up optional rules to notify you and your team when a user's payment fails.

LogSnag also allows you to track user journeys and create a timeline of their actions to monitor the users' payment history and any other activity they have done in your application. This way, you can always track the activity of a specific user, such as when their payment fails and any other activity they have done in your application.
