🔧 Partner Integration Setup

Usage:
  node setup_partners.js

Notes:
  - SatLoc authentication now uses customer-specific credentials
  - Credentials are stored in PartnerSystemUser records, not environment variables
  - Global SatLoc credentials (SATLOC_EMAIL, SATLOC_PASSWORD) are deprecated

Environment Variables (Optional):
  SATLOC_API_ENDPOINT             - SatLoc API endpoint (default: https://www.satloccloud.com/api/Satloc)
  SATLOC_API_TIMEOUT             - API timeout in ms (default: 30000)
  SATLOC_RETRY_ATTEMPTS          - Retry attempts (default: 3)
  PARTNER_SYNC_INTERVAL          - Sync interval in ms (default: 300000)

Example .env file:
  SATLOC_API_ENDPOINT=https://www.satloccloud.com/api/Satloc
  SATLOC_API_TIMEOUT=30000
  PARTNER_SYNC_INTERVAL=300000

After setup, restart your application to load the partner services.
