### GET Operation Overview

Source: https://github.com/tinode/chat/blob/master/docs/API.md

The GET operation is used to query metadata and message history for a topic. The requester must be subscribed and attached to the topic for a full response. Different parameters can be specified within the `what` field to retrieve specific types of data.

```APIDOC
## GET Operation

Query topic for metadata, such as description or a list of subscribers, or query message history. The requester must be [subscribed and attached](#sub) to the topic to receive the full response. Some limited `desc` and `sub` information is available without being attached.

### Parameters

- **id** (string, optional): Client-provided message id.
- **topic** (string, required): Name of the topic to request data from.
- **what** (string, required): Space-separated list of parameters to query. Unknown values are ignored.

### Supported `what` values and their parameters:

#### `desc`

Query topic description. Server responds with a `{meta}` message containing requested data. See `{meta}` for details.
If `ims` is specified and data has not been updated, the message will skip `trusted`, `public`, and `private` fields.
Limited information is available without [attaching](#sub) to topic first.
See [Trusted, Public, and Private Fields](#trusted-public-and-private-fields) for `trusted`, `private`, and `public` format considerations.

- **desc.ims** (timestamp, optional): If modified since - return public and private values only if at least one of them has been updated after the stated timestamp.

#### `sub`

Get a list of subscribers. Server responds with a `{meta}` message containing a list of subscribers. See `{meta}` for details.
For `me` topic the request returns a list of user's subscriptions. If `ims` is specified and data has not been updated, responds with a `{ctrl}` "not modified" message.
Only user's own subscription is returned without [attaching](#sub) to topic first.

- **sub.ims** (timestamp, optional): If modified since - return public and private values only if at least one of them has been updated after the stated timestamp.
- **sub.user** (string, optional): Return results for a single user, any topic other than 'me'.
- **sub.topic** (string, optional): Return results for a single topic, 'me' topic only.
- **sub.limit** (integer, optional): Limit the number of returned objects.

#### `tags`

Query indexed tags. Server responds with a `{meta}` message containing an array of string tags. See `{meta}` and `fnd` topic for details.
Supported only for `me` and group topics.

#### `data`

Query message history. Server sends `{data}` messages matching parameters provided in the `data` field of the query.
The `id` field of the data messages is not provided as it's common for data messages. When all `{data}` messages are transmitted, a `{ctrl}` message is sent.

- **data.since** (integer, optional): Load messages with server-issued IDs greater or equal to this (inclusive/closed).
- **data.before** (integer, optional): Load messages with server-issued sequential IDs less than this (exclusive/open).
- **data.limit** (integer, optional): Limit the number of returned objects, default: 32.

#### `del`

Query message deletion history. Server responds with a `{meta}` message containing a list of deleted message ranges.

- **del.since** (integer, optional): Load deleted ranges with the delete transaction IDs greater or equal to this (inclusive/closed).
- **del.before** (integer, optional): Load deleted ranges with the delete transaction IDs less than this (exclusive/open).
- **del.limit** (integer, optional): Limit the number of returned objects, default: 32.

#### `cred`

Query [credentials](#credentail-validation). Server responds with a `{meta}` message containing an array of credentials. Supported for `me` topic only.

#### `aux`

Query auxiliary topic data. Server responds with a `{meta}` message containing an object with auxiliary key-value pairs.
