Memory

• 2026-09-03

• No path changes (schema description only)
• Clarified the DataMappingCore description: the PATCH body requires at least one field.

• 2026-09-30

• The source field on observations and conversation summaries, and the source filter
• on ListProfileObservations, now also accept forward slashes (/). The pattern is
• ^[a-zA-Z0-9 _./-]+$. This is additive and backwards compatible: every previously
• valid value is still accepted.

• 2026-09-03

• UpdateStore, UpdateTraitGroup, and UpdateDataMapping now require a body with at least one property. An empty {} gets a 400.

Webhooks

• 2026-09-24

• Changed: GET /v1/Webhooks/Settings now documents each item as the full Setting rather than SettingSummary, adding auth, signature, connection and edgeZones to the list response. The service already returned these fields; only the schema understated them. Additive for consumers — no field is removed or renamed. The now-unreferenced SettingSummary schema is removed.
