Agent Metadata
Known Gotchas
- ⚠ REST and GraphQL APIs have different feature coverage — verify operation availability in your preferred interface
- ⚠ Store ID is part of every API call — agents must configure per-store credentials for multi-tenant deployments
- ⚠ Subscription billing intervals use Swell-specific enum values — refer to documentation for valid period values
- ⚠ Webhook payloads contain full object data — process events idempotently as duplicates can occur
- ⚠ Test and live modes use separate API keys — always verify environment context in automation
