Avoid When
You run a consumer e-commerce affiliate program or need an enterprise-scale platform with custom contract management.
Use Cases

Agent Metadata
Known Gotchas
- ⚠ Rate limits are undocumented — agents must implement conservative backoff with jitter
- ⚠ Customer creation is not idempotent; checking for existing customer by email before creating is required
- ⚠ Conversion events (for triggering rewards) require specific group and trigger key configuration
- ⚠ API uses different key pairs for public (tracking) vs private (management) operations
- ⚠ Reward payouts require partner to have a connected payout method — agents should handle unfulfilled rewards gracefully
