}Restrictions
| Aspect | Value |
|---|---|
| Rate limits | 1,000 requests/minute; 50 requests/second per account |
| Permissions | None — any valid app_key can call this operation |
Usage
- This is the current field-model route for discovering RUM fields.
- Use returned
field_keyvalues in RUM data queries and facet-count requests. - Set
is_facet: trueto return only fields that support value distribution queries.
Authorizations
App key issued from the Flashduty console under Account → APP Keys. Required on every public API call. Keep it secret — it grants the same access as the owning account.
Body
Filter parameters for listing RUM field definitions.
When omitted or null, return all fields. When true, return only facet-enabled fields. When false, return only fields that are not facet-enabled.
Filter by RUM data scopes; unknown values are rejected with a parameter error. Omit to list fields of all scopes.
| Value | Meaning |
|---|---|
session | User sessions |
view | Page views |
action | User actions |
error | Error events |
resource | Resource loads |
long_task | Long tasks |
vital | Performance vitals (Web Vitals, etc.) |
issue | Aggregated error-tracking issues |
sourcemap | Sourcemap / symbol files |
session, view, action, error, resource, long_task, vital, issue, sourcemap Response
Success
Success response envelope. On every 2xx response, request_id identifies the call (also mirrored in the Flashcat-Request-Id header) and data holds the endpoint-specific payload. Failure responses use a different shape — see ErrorResponse.
