# Pause a session

> Halt a running session without losing state.

Pauses a running session. The agent stops processing but its state is fully preserved. You can [resume](/computer-use-agents/sessions/resume) it later to continue from exactly where it left off.

**Returns** `202 Accepted`. The pause command is delivered asynchronously.
