Track user sign in events in OCaml

Most of the time, when building a OCaml product that requires users to authenticate and sign in to access the product, you may decide that it is essential to track the sign-in attempts.

Monitoring the sign-in events is an excellent way to track the number of users who continue to log in and use your OCaml application. This is a great way to gauge the effectiveness of your product and measure your user retention rate.

A good understanding of this metric is critical to the success of a product. It can give you great insight into how your business grows and how your users interact with your OCaml product.

An easy way to set up event tracking is to use LogSnag, a simple event tracking tool that works seamlessly with OCaml.

Start monitoring user sign-in events

1. Sign up for a free LogSnag account.
2. Create your first project from the dashboard.
3. Head to settings and copy your API token.

OCaml code snippets

All you have to do next is to copy the following code snippets into your OCaml code and replace the YOUR_API_TOKEN and project values with your API token and project name.

open Lwt
open Cohttp
open Cohttp_lwt_unix

let postData = ref "{\"project\":\"my-saas\",\"channel\":\"auth\",\"event\":\"User Signed In\",\"description\":\"email: john@doe.com\",\"icon\":\"🔓\",\"notify\":true}";;

let reqBody = 
  let uri = Uri.of_string "https://api.logsnag.com/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) ->
  body |> Cohttp_lwt.Body.to_string >|= fun body -> body

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