# set_session

The `set_session` step.

Loads the named session's storage state at this point in the program. Rarely needed; prefer `options.session`.

Type: `string`

Every step also takes the [common step keys](https://docs.kaab.ist/reference/dsl/steps#common-keys): `expect`, `id`, `if`, `name`, `on_error`, `optional`, `retry`, `side_effect`, `timeout_ms`, `x_kaab`.
