In case of Client-side:

This is just an ordered list – the order of the changes matters; they are applied to the webpage in the exact order from top to bottom. There are multiple available modification types to choose from, and they are described later in the section Changes types. Each Experiment also has a few settings associated with it, just like any other object at Intempt.

In case of Server-side:

it is a free json object.

How to use a Server-side

Required

1. a key from API keys menu; example 36e82934fff945278268971cd3b4d32e.8911b9bc1e3f469a863a7e047cd51fdc
2. an existing experiment; example id: 99afebd5-885e-48de-9789-704f7ff12437
3. the name of the organization and project
4. add our sdk

npm i @intempt/sdk

Define the configuration

const configuration = new IntemptSdk.Configuration({
  username: process.env.INTEMPT_USERNAME, // 36e82934fff945278268971cd3b4d32e
  password: process.env.INTEMPT_PASSWORD, // 8911b9bc1e3f469a863a7e047cd51fdc
});

Instantiate the experiments API

const experimentsApi = new IntemptSdk.CDPMetadata.ExperimentsApi(configuration);

Make the call

await experimentsApi.chooseVariant({  
  orgName: process.env.INTEMPT_ORG_NAME,  
  projectName: process.env.INTEMPT_PROJECT_NAME,  
  experimentId: '99afebd5-885e-48de-9789-704f7ff12437',  
  chooseVariant: {  
    userIdentifier: email 
  }  
});
