# UpdateEmbedderRequestBase - `displayName` (`string | null`, optional): User-facing name of the embedder - `description` (`string | null`, optional): Description of the embedder - `endpointUrl` (`string | null`, optional): Replacement base HTTP(S) endpoint. Omit to preserve the stored value. Gemini endpoint URLs must not contain query parameters. - `apiPath` (`string | null`, optional): Replacement provider-relative request path. Omit to preserve the stored value, except that changing the Gemini backend without apiPath selects that backend's default; send blank to restore the provider default. For Gemini, this is an API version: /v1beta for Developer and /v1 for Google Cloud. - `modelIdentifier` (`string | null`, optional): Model identifier - `dimensionality` (`number | null`, optional): Output vector dimensions - `distributionType` (`DistributionType | null`, optional): Type of embedding distribution (DENSE or SPARSE) - `maxSequenceLength` (`number | null`, optional): Maximum input sequence length - `credentials` (`EndpointAuthentication | null`, optional): Replace stored credentials. Omit this field to preserve the current credentials; a present empty payload is invalid and never clears them. - `replaceLabels` (`Record | null`, optional): Replace all existing labels with these (mutually exclusive with mergeLabels) - `mergeLabels` (`Record | null`, optional): Merge these labels with existing ones (mutually exclusive with replaceLabels) - `version` (`string | null`, optional): Version information - `monitoringEndpoint` (`string | null`, optional): Monitoring endpoint URL - `dashscopeApiDialect` (`DashScopeApiDialect | null`, optional): Update the DashScope request and response API dialect. Valid only for the DASHSCOPE provider. Omit to preserve the stored dialect. Changing apiPath to a recognized canonical DashScope dialect infers its matching dialect; a custom path preserves an existing dialect, while a legacy null dialect is inferred. Allowed values for this field: EMBEDDING_NATIVE_TEXT, EMBEDDING_NATIVE_CONTENTS, OPENAI_COMPATIBLE. - `geminiEndpointConfig` (`GeminiEndpointConfig | null`, optional): When present, atomically replaces the complete Gemini backend routing configuration. Valid only for a GEMINI embedder. Omit to preserve the stored configuration; the gRPC service validates the backend-specific projectId and location contract.
