## Overview

This tutorial builds on your first telemetry workflow (from [Tutorial 1](../tutorial-1/overview)) by showing how to reproduce it using one of Sift's APIs.

You'll work with the same preprocessed dataset from the Mars Environmental Monitoring Station (REMS).
While you'll still use the UI to view results, you'll learn how to import data, create a Rule, generate a Report, and define a Calculated Channel through code.

By using Sift's API, you'll see how these workflows can be created in code and immediately observed in the UI, giving you a deeper understanding of how the programmatic and visual interfaces complement each other.

## Prerequisites

* Basic understanding of a REST API.
* Basic understanding of cURL commands.
