# JSON.OBJKEYS

> Get JSON object keys.

Use `JSON.OBJKEYS` to list the field names of the objects a path selects.

Without a path the root value is used. The reply holds one list of keys per match, with null for matches that are not objects. Only the field names come back, not the values, which makes it a cheap way to inspect the shape of a document before reading it.

## Syntax

```redis theme={"system"}
JSON.OBJKEYS <key> [path]
```

## Arguments

| Argument | Required | Repeatable | Description                                   |
| -------- | -------- | ---------- | --------------------------------------------- |
| `key`    | Yes      | No         | JSON document key.                            |
| `path`   | No       | No         | Path selecting objects; defaults to the root. |

## Important points

* Raw TCP examples pass JSON values as valid JSON text. Typed Upstash SDK helpers serialize native objects and values for you.
* Paths beginning with `$` use JSONPath and can match multiple values, so many JSON commands return an array of per-match results.

## Response

The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.

| Protocol | Reply                                                                                        |
| -------- | -------------------------------------------------------------------------------------------- |
| RESP2    | Array of arrays of bulk-string object keys or null values, or Null bulk string or null array |
| RESP3    | Array of arrays of bulk-string object keys or null values, or Null                           |

<Note>
  Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.

## Examples

TCP examples use the TLS `REDIS_URL` from the Upstash console. REST examples use `UPSTASH_REDIS_REST_URL` and `UPSTASH_REDIS_REST_TOKEN`.
