I'm seeing different versions of the GrowthBook documentation for Kotlin (back end, not Android), and I'm struggling to get my project off the ground. When I click on the SDK I set up, I see this sample:

GBContext context = GBContext.builder()
    .featuresJson(featuresJson)
    .attributesJson(userAttributesObj.toString()) // Optional
    .encryptionKey("****") // You may want to store this in an environment variable
    .trackingCallback(trackingCallback)
    .build();
GrowthBook growthBook = new GrowthBook(context);

But when I check https://github.com/growthbook/growthbook-kotlin , I see this:

var sdkInstance: GrowthBookSDK = GBSDKBuilderJAVA(apiKey = <API_KEY>,
    hostURL = <GrowthBook_URL>,
    attributes = <Hashmap>,
    features = <Hashmap>,
    trackingCallback = { gbExperiment, gbExperimentResult ->

}).initialize()

The sample from

<http://app.growthbook.io|app.growthbook.io>

uses

GBContext

and has no API key, while the github sample uses

GBSDKBuilderJAVA

and requires an API key. Which is correct?

Hi @dazzling-garden-98992, thank you for the feedback. Please use the docs from GitHub repo, we will update soon docs on the website.

@most-spoon-61816 is the API Key only required for having write access to features from the SDK? If I only want to read features, what should I be using?

hi @dazzling-garden-98992, the example in your first message is for this dependency:

maven {
        url = uri("<https://jitpack.io>")
    }
com.github.growthbook:growthbook-sdk-java:0.3.0

it can be used both in java and in kotlin. the growthbook-kotlin project is android only and would not be compatible. • here are the docs for the java SDK: https://docs.growthbook.io/lib/java – at the bottom there are some examples (java spring, kotlin with ktor) • here's the repository: https://github.com/growthbook/growthbook-sdk-java please note, the latest version of the java SDK is now 0.5.0. you may want to choose version 0.4.0 and up if you'd like networking support.

this did it for me, thanks!
