In today's landscape, many services are adopting a pay-as-you-go approach, which can be based on either monthly usage limits or metered usage. This trend is particularly prevalent in cloud computing, software, and various online services. If you are developing a Ocaml-based service, you will likely need to establish your usage model and associated limits.
Irrespective of your specific implementation, it becomes essential to create an internal system for tracking usage and setting up notifications to alert you and your team when a user reaches their designated limit. This is a common challenge, as it provides valuable insights into how your users utilize your service, enabling you to enhance your product based on user behavior.
Enter Palzin Track, a service designed to offer real-time event tracking. It serves as an ideal solution for this task and seamlessly integrates with Ocaml. Palzin Track simplifies the process of transmitting events to your dashboard and facilitates push notifications whenever critical events occur.
For instance, consider a scenario where you are developing a Ocaml-based service that allows users to upload files, but you wish to impose a limit of ten uploads per user. Palzin Track comes to the rescue by enabling you to send events to your dashboard whenever a user uploads a file. Additionally, you can configure a rule to notify you when a user hits the ten-file upload limit. This functionality ensures you are promptly informed when a user reaches their designated threshold, empowering you to take further action as needed.
Copy the following code snippet to your OCaml project. Please note that you will need to replace the API token with your own.

open Lwt
open Cohttp
open Cohttp_lwt_unix
let postData = ref "{\"project\":\"my-project\",\"channel\":\"limits\",\"event\":\"Usage Limit Exceeded\",\"description\":\"The user has exceeded the usage limit for the service.\",\"icon\":\"🚨\",\"notify\":true}";;
let reqBody =
let uri = Uri.of_string "https://api.palzin.live/v1/log" in
let headers = Header.init ()
|> fun h -> Header.add h "Content-Type" "application/json"
|> fun h -> Header.add h "Authorization" "Bearer YOUR_API_TOKEN"
in
let body = Cohttp_lwt.Body.of_string !postData in
Client.call ~headers ~body `POST uri >>= fun (_resp, body) ->

let () =
let respBody = Lwt_main.run reqBody in
print_endline (respBody)
