Code Examples

What this page is for. Getting a developer who is new to brainCloud, or new to one corner of it, to the example code that already solves their problem. Each article takes a single feature, explains it in about a page, and links line-for-line into the working app the code came from, so the step after reading is opening real source rather than a blank file.

It is not the API reference. The API Reference is the authority on every method, its parameters, and its response shape, and it's linked in the bar at the top of this page. This document sits in front of it, answering what a reference can't: which service to reach for, what the call looks like inside an app that shipped, and which mistakes are worth knowing about before you make them.

How to use it. Starting out, read from the top: Tier 1 is the handful of calls every app needs on day one. Later tiers lean on earlier ones in places, and each article names what it builds on. Looking for one specific thing instead, the map below lists every article against the brainCloud services it touches, and the rail on the left jumps straight to any article.
