Browserbase Session Extend

Use this endpoint when an active Browserbase headless browser session is running and needs more time to complete its task before the session timeout occurs. Prefer this over creating a new session when you want continuity of the current browser state, cookies, and loaded pages without interruption.

• Session ID not found — returns 404 if the session does not exist
• Session already terminated — cannot extend an expired or closed session
• Invalid extension duration — returns 400 if the time value is invalid or out of range
• Unauthorized — returns 401/403 if the API credentials are missing or invalid
• Maximum session duration reached — extension refused if the session has hit the provider's maximum allowed length
