Features - Endpoints - Data API

Features endpoint

Manage Features in your Item bank.

Endpoints:

Usage

The format of requests to the Data API use the following syntax:

https://data.learnosity.com/{LTS_VERSION}/{endpoint}

For example, to use the v2025.1.LTS version and the itembank/items endpoint, you would create a request like so:

https://data.learnosity.com/v2025.1.LTS/itembank/items

Important Data API is not a REST API. All requests must use the POST method with the action request body parameter specifying the operation to use. The Learnosity SDK must be used to make requests to Data API.

Note Data API usage is subject to rate limits.
