Many Ocaml applications employ a subscription-based model, wherein users make regular payments, either monthly or annually, to access the software, categorizing them as Software as a Service (SaaS) applications. These subscriptions grant users access for the designated time period. Alternatively, some applications adopt a pay-as-you-go model, charging users based on their actions within the application.
In both scenarios, a common challenge arises when users opt to cancel their subscriptions, a phenomenon known as churn. Consequently, monitoring an application's churn rate becomes a pivotal metric, with a substantial impact on revenue and the application's long-term viability.
Hence, SaaS applications must proactively track subscription cancellations, understand the reasons behind these cancellations, and keep a close watch on the overall churn rate. This approach ensures continuous awareness of the application's performance, facilitating swift action when necessary. For instance, a high churn rate can trigger initiatives to enhance the user experience, while the cancellation of a subscription by a high-value user may prompt efforts to retain that user.
Palzin Track, a robust, real-time event tracking tool seamlessly compatible with any Ocaml application, provides an effective solution for monitoring subscription cancellations and churn rates. With Palzin Track, you gain the flexibility to set up event tracking for diverse aspects of your Ocaml application, including real-time tracking of subscription cancellations. Additionally, you can establish optional alert rules to promptly notify you and your team when a user cancels their subscription.
Furthermore, Palzin Track empowers you to trace user journeys and create event timelines for individual users, allowing you to monitor specific user activities, such as subscription cancellations, alongside their broader interactions within your application.
To track subscription cancellations in your OCaml application, you can use the following code snippet. Please replace the YOUR_API_TOKEN with your API token and update the project and channel names.
