title: XGROUP CREATECONSUMER
---
Create a consumer named `<consumername>` in the consumer group `<groupname>` of the stream that's stored at `<key>`.

Consumers are also created automatically whenever an operation, such as [`XREADGROUP`]({{< relref "/commands/xreadgroup" >}}), references a consumer that doesn't exist.
This is valid for [`XREADGROUP`]({{< relref "/commands/xreadgroup" >}}) only when there is data in the stream.
