# Stream Seek

`POST /api/v1.msgs.stream.seek`

Repositions a consumer group's read cursor on a topic.

Provide exactly one of `offset`, `position`, or `timestamp`. When using `offset`, the topic
must include a partition suffix (e.g. `ns:my-topic~0`). The `position` field accepts
`"earliest"` or `"latest"` and may be used with or without a partition suffix. The `timestamp`
field accepts a Unix timestamp in milliseconds and seeks to the first message at or after that
time.

  - `topic` string, required
