GET /{index}/_mapping
Api key auth

For data streams, the API retrieves mappings for the stream’s backing indices.

Required authorization

  • Index privileges: view_index_metadata

Path parameters

  • index string | array[string] Required

    Comma-separated list of data streams, indices, and aliases used to limit the request. Supports wildcards (*). To target all data streams and indices, omit this parameter or use * or _all.

Query parameters

  • allow_no_indices boolean

    If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices.

  • expand_wildcards string | array[string]

    Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden. Valid values are: all, open, closed, hidden, none.

    Values are all, open, closed, hidden, or none.

  • ignore_unavailable boolean

    If false, the request returns an error if it targets a missing or closed index.

  • local boolean Deprecated

    If true, the request retrieves information from the local node only.

  • master_timeout string

    Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

    Values are -1 or 0.
