Language: en

Guided actions for Redis keys, hashes, and lists

## Usage and specifics

Choose an operation for keys, hashes or lists. ttlSeconds uses seconds. The existing Redis value type must match the operation.

Technical type : `redis`. Runtime : `nodulz`.

## Credentials and prerequisites

- [Create and configure the credential : redis](/docs/credentials/redis)

Create credentials in your nodulz instance’s Credentials area, then select them on the node. Availability depends on ownership and sharing. See the [credentials guide](/docs/credentials) for access and rotation.

## Parameters

Names below are technical keys. Defaults are not a ready-to-run configuration: complete fields required by your operation. Paths containing [] describe list items; some fields depend on the selected mode.

| Parameter | Type | Default | Values / limits |
| --- | --- | --- | --- |
| `credentialId` | `string` | `""` | - |
| `operation` | `enum` | `"get"` | `get`, `set`, `delete`, `exists`, `increment`, `expire`, `ttl`, `hash_get`, `hash_set`, `hash_delete`, `list_push`, `list_range` |
| `key` | `string` | `""` | - |
| `field` | `string` | `""` | - |
| `value` | `string` | `""` | - |
| `ttlSeconds` | `number` | `0` | -; ≥ 0 |
| `incrementBy` | `number` | `1` | - |
| `rangeStart` | `number` | `0` | - |
| `rangeStop` | `number` | `-1` | - |

## Configuration help

| Setting | Purpose and guidance |
| --- | --- |
| `credentialId`<br>Redis credential | Select a Redis vector credential with a redis:// or rediss:// URL and optional password. |
| `operation`<br>Operation | Choose a guided Redis command. |
| `key`<br>Key | Redis key. Workflow expressions are supported. |
| `field`<br>Field | Field name within the hash. |
| `value`<br>Value | Text to write to Redis. Workflow expressions are supported. |
| `ttlSeconds`<br>Time to live (seconds) | For SET, 0 keeps the key without expiration. For EXPIRE, enter a positive value. |
| `incrementBy`<br>Increment | Integer added to the current value. May be negative. |
| `rangeStart`<br>Start | Inclusive first index. Negative indexes count from the end. |
| `rangeStop`<br>Stop | Inclusive last index. -1 means the final item. |

## Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

```json
{
  "credentialId": "",
  "operation": "get",
  "key": "",
  "field": "",
  "value": "",
  "ttlSeconds": 0,
  "incrementBy": 1,
  "rangeStart": 0,
  "rangeStop": -1
}
```

## Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
