Usage
- Send the complete configuration, not a patch: rule order is the priority, so a partial update has no unambiguous meaning.
- Every call publishes a new version, even when the content is unchanged or
enabledisfalse; only the 50 most recent versions are kept. - Call
POST /rum/application/remote-config/previewfirst to check what clients would receive. - The caller must be able to edit the application: the account owner, an account admin, the application’s creator, or a member of its owning team; anyone else gets
AccessDenied. - Every call is recorded in the account audit log. Don’t put secrets in request fields.
Authorizations
APP Key created in the Flashduty console under My → APP Key. Send it as the app_key query parameter or in the Fd-App-Key request header. Its effective access is the intersection of the key's permission scope and the creator's current role permissions. Keep it secret.
Body
application/json
Publish a whole new remote configuration version. The client sends the complete object, not a patch: rule order carries meaning.
RUM application ID. Get application IDs via POST /rum/application/list.
The complete configuration to publish.
Show child attributes

Optional free-text note (not an enum) on why this version was published, at most 255 characters; stored verbatim and returned as reason by POST /rum/application/remote-config/history/list.
Maximum string length:
255Response
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.
