This guide demonstrates how to fetch and browse user profiles using Algolia’s Advanced Personalization API. The provided code snippets offer a straightforward way to interact with the API and retrieve user data for segmentation purposes. Exporting an audience lets you create groups of users who share a specific , so you can run focused email or ad campaigns. For example, you could export an audience of users with a high affinity for camping or hiking and send them promotional content about outdoor gear.

​
Before you begin

Ensure you have a query string builder utility, such as the qs library available in your project.

​
Fetch user profiles

The Advanced Personalization API exposes an endpoint to retrieve user profiles based on specified parameters. Here’s a function to communicate with this endpoint:
JavaScript
import qs from 'qs';

export async function fetchUserProfiles(params) {
  const { appId, apiKey, region, ...usersParams } = params;
  const response = await fetch(
    `https://ai-personalization.${region}.algolia.com/2/users${qs.stringify(
      usersParams,
      { addQueryPrefix: true }
    )}`,
    {
      headers: {
        'X-Algolia-Application-Id': appId,
        'X-Algolia-API-Key': apiKey,
      },
    }
  );

  if (!response.ok) {
    const errorMessage = await response.text();
    throw new Error(errorMessage);
  }

  const json = await response.json();

  return json;
}
The function takes as parameters an object containing:

​
Browse user profiles

To iterate through all user profiles and handle pagination automatically, use this function:
JavaScript
export async function browseUserProfiles(callback, params) {
  let nextPageToken = '';
  do {
    const response = await fetchUserProfiles({
      ...params,
      nextPageToken,
    });
    nextPageToken = response.nextPageToken;

    await callback(response.users);
  } while (nextPageToken);
}

​
Process batches of user profiles

Here’s an example of how to process batches of user profiles:
JavaScript
async function processUsers(users) {
  // Perform operations with all users in the batch
}

await browseUserProfiles(processUsers, {
  appId: 'ALGOLIA_APPLICATION_ID',
  apiKey: 'ALGOLIA_SEARCH_API_KEY',
  region: 'us',
  affinity: 'category:camping',
  limit: 100
});
Segment users based on their category:camping affinity and implement targeted strategies for these users. For example, send them an email about a discount on camping products. Find the list of available parameters in the REST API documentation.
