Mark one conversation read in the stored inbox. This action can change or spend something, and it happens right away. Plan: Free and Connect.

```
POST https://api.heyreagent.com/v1/actions/mark_read
Authorization: Bearer YOUR_KEY
content-type: application/json

{
  "readKey": "PASTE_READ_KEY_HERE"
}
```

## What you give it

- `readKey` (needed): a read key. readKey returned by list_conversations Where to get it: Run `list_conversations` and use `inbox[].readKey`.

## What you get back

- `success`

## Good to know

- It changes this app's copy only; LinkedIn is not told. set_chat_status marks a conversation read on LinkedIn itself.
- Any text is accepted as readKey and answered with success, so a stale key fails silently.
