  • Tokens are campaign-scoped (different token per campaign for same investor)
  • Investment amounts shown as tiers (small/medium/large), not exact values
  • No PII (email, name, address) is returned

Tier 2 (Founders/Employees) - Full data with detail_level=full:

  • Real investment IDs (linkable to Wefunder admin)
  • Investor name, email, and username
  • Exact dollar amounts

Access: Requires Tier 1+ access approval from Wefunder admin.
