We use API actually for post data and grab data.

Lets say you want to create a log file on the form or other service. In this case you want to monitor if the service is correct or is down or error.

So when you already post it with API, then you can collect the data easily. Even by its own receiver API or just directly from the dashboard that you set with the API.

Its easy enough to see your service platform performance from data reported by the API.
