---

The lists.sr.ht API allows you to browse, create, and subscribe to mailing lists
on lists.sr.ht programmatically. This API follows the [standard sourcehut API
conventions](/api-conventions.md).

## Authentication

flow](https://man.sr.ht/meta.sr.ht/oauth-api.md). The following OAuth scopes are
available for lists.sr.ht:

- **emails:read**: read emails received from lists.sr.ht users
- **lists:read**, **list:write**: read & write your mailing lists
- **subs:read**, **subs:write**: read & write your subscriptions
- **patches:read**, **patches:write**: read & write patchsets on lists

## Resources

### Email resource

```json
{
  "id": integer,
  "created": "timestamp",
  "subject": "message subject",
  "message_id": "value of the Message-ID header",
  "parent_id": integer or null,

  "is_patch": boolean,
  "is_request_pull": boolean,

}
```

**Notes**

  a sr.ht account.

  "permissions": {
    "nonsubscriber": [ list of permissions ],
    "subscriber": [ list of permissions ],
    "account": [ list of permissions ]
  }
}
```

**Notes**
