Fetch Token

The FetchToken API retrieves the creative token for a user who was previously registered.

Usage

import {
  Client, UserData, FetchToken
} from "@geeklab.app/audiencelab_nodejs_sdk";

const client = new Client({
  apiKey: "YOUR_API_KEY",
  baseUrl: "https://analytics.geeklab.app",
});

const userData = new UserData()
  .setUserId("user_12345")
  .setUserIp("203.0.113.42");

const response = await new FetchToken(client, userData).send();
userData.setUserCreativeTokenInfo(response);

After a successful fetch, call userData.setUserCreativeTokenInfo(response). The SDK stores creative token data, retention dates, cumulative values, and merges returned whitelisted properties with caller-set whitelisted properties.

When to Use

Use FetchToken when:

• The user was previously registered and you need to retrieve their token
• The cached token was lost or expired
• You want to verify the current token assignment

For first-time user registration (which also returns a token), use Register User instead.
