# markMessageRead

mutation · in the family [Your own session](/reference/your-own-session/)

## What it does

Mark one of your messages as read. Team messages don’t track per-person reads.

Mark one of YOUR messages read. An absent row refuses NOT_FOUND/MESSAGE (team messages are unreachable here — no per-member team read state v1); an already-read message returns unchanged (FIRST read wins). Requires authentication.

## What happens

The first read sets the time; reading again changes nothing.

## Who may call it
