1. Introduction

Asleep Track SDK is a software development kit that enables developers to create applications that monitor the sleep of users. The SDK provides tools and resources to integrate sleep-tracking features into mobile applications.

One of the primary features of the Asleep Track SDK is its ability to track the user's sleep in real time, including sleep stages and breathing stability. The SDK can gather information about the user's sleep patterns, including the amount of time spent in each stage of sleep. This information can be used to provide insights into the user's sleep quality and recommend improvements to their sleep habits.

Overall, Asleep Track SDK is a powerful tool for developers looking to create sleep-tracking applications. Asleep’s business partners only need to care about the UI/UX of their applications, and Asleep Track SDK will take care of all core functions for sleep monitoring.

With its advanced features and easy integration, it offers a comprehensive solution for developers looking to improve the sleep quality of their users.

2. Interfaces

2.1 Asleep.AsleepConfig

AsleepConfigcontains all the necessary configuration information, including the API key, user ID, and base URL for API communication. The configuration information of AsleepConfig is used throughout the sleep tracking features of the SDK.

2.2 Asleep.SleepTrackingManager

The SleepTrackingManager is used to manage sleep sessions for a specific user ID passed through AsleepConfig. This manager can start and stop tracking and recall the latest sleep reports from users.

2.3 Asleep.Reports

Reports is used to manage sleep reports of a specific user ID passed through AsleepConfig. This allows you to look up the IDs of all sleep session that occurred during a specific period of time, and to look up a detailed sleep report for each sleep sessionID.

2.4 Asleep.AsleepErrorCode

This document describes all available error codes to help developers understand what is happening inside the SDK.
