REST API

Sandbox Setup: This section describes how to quickly learn, explore and test your Advertiser APIs with a sandbox environment.

The sandbox environment provides a safe testing ground that mirrors production configuration while being isolated from live data. The setup process is identical to production.


Environment Overview

  • REST API Base URL: https://api-sandbox.cardlytics.com
  • Purpose: API testing, development, and file transfer testing
  • Configuration: Identical to production environment
  • Data: Test data only - no live customer information

1. Obtain Sandbox Credentials

Contact your Cardlytics representative to get sandbox API credentials:

  • client_id for sandbox environment
  • client_secret for sandbox environment

2. Authentication and API Endpoints

Authentication and all API endpoints use the same paths as production, just with the sandbox base URL
