Agent Metadata
Known Gotchas
- ⚠ Two separate APIs (REST and legacy SOAP) with different auth and different capabilities — check which one has the feature you need
- ⚠ Account subdomain (MID) varies per tenant — all API URLs are account-specific
- ⚠ REST API covers modern features; SOAP API still required for some legacy operations like sending emails
- ⚠ Access tokens expire after 20 minutes — agents must handle refresh proactively
- ⚠ Data Extensions are the primary data store — understanding the schema is essential
- ⚠ Async job pattern for bulk operations — must poll for completion before using results
