Using Postman to Test and Debug xAPI Statements

Image
When working with xAPI (Experience API) , developers frequently need a fast way to push statements into a LRS (Learning Record Store) and inspect how the LRS responds. Postman is an ideal tool for that: it lets you build requests, inspect responses, save test collections, and iterate without writing an integration first. Why Use Postman for xAPI? Quick testing — send statements without writing client code. Debugging — inspect response bodies, codes, and headers from your LRS. Learning — experiment with statement shapes and LRS behavior safely. Repeatable workflows — save requests and environments for future use. Setting Up Postman for xAPI 1. Install Postman Get Postman from postman.com . Desktop or the web app both work. 2. Identify Your LRS Endpoint Most LRS endpoints are at a base URL with an /xapi/ path. Example: https://your-lrs-domain.com/xapi/ 3. Get Authen...

Creating Your Own xAPI Wrapper: A Beginner-Friendly Tutorial

If you’re working with xAPI for the first time, you’ve probably noticed that sending and receiving statements directly through raw HTTP requests can feel intimidating. That’s where an What is an xAPI Wrapper? An xAPI wrapper is a reusable piece of code (usually written in JavaScript for web-based learning content) that simplifies interaction with a Learning Record Store (LRS). Instead of writing full fetch or XMLHttpRequest calls every time, you can call a simple function like: sendStatement("John Doe", "completed", "Module 1: Introduction to xAPI"); The wrapper handles authentication, formatting, and sending the xAPI statement in the background.   Why Do You Need a Wrapper? Saves time: No need to rewrite API calls every time you send a statement. Reduces errors: Handles JSON formatting and required fields consistently. Makes code cleaner: Developers can use simple function calls instead of complex xAPI syntax. Reusable: Once...

xAPI + WordPress: A Developer’s Guide to Using GrassBlade or Other Plugins

Image
Learning doesn’t just happen inside an LMS anymore. If you’re an eLearning developer using WordPress , you’ll want a reliable way to track learning events and send them to a Learning Record Store (LRS) . This article explains how to implement xAPI in WordPress — focusing on GrassBlade xAPI Companion and other plugin options, plus practical tips for developers. What is xAPI (in a WordPress Context)? xAPI (Experience API) is a specification for tracking learning activity across platforms. Unlike SCORM, xAPI is flexible: it can track activities that happen in WordPress pages, embedded videos, quizzes, simulations, or even offline experiences, then send those records to an LRS for analysis. Track fine-grained actions (e.g., video play , quiz answer ). Connect WordPress content with external apps and analytics. Enable adaptive and personalized learning workflows driven by real data.   Why Use WordPress with xAPI? WordP...
