 - **Note TypeId**: Required when posting notes. The public BMS v2 Swagger does not clearly expose a generic note-type lookup endpoint for all tenants, so you may need tenant-specific documentation or known values.
 - **Rate limits**: Not documented in the Swagger spec. Treat as standard REST API — avoid tight loops; add a small sleep between bulk operations.
 
+## Note Type IDs (Grand Portage Tenant)
+
+Based on testing for Grand Portage, the following note type IDs are valid:
+
+- `0` — Email Sent
+- `1` — Email Received
+- `2` — General Notes
+- `3` — Phone Call
+- `4` — Resolution
+
+Note: These are tenant-specific and may differ in other BMS deployments. The public Swagger does not fully expose note type lookups.
