# Uplink Data Format V2

{% hint style="success" %}
**Best for Cloud to Cloud transfers**
{% endhint %}

AlphaX expects a JSON formatted object with the following key:value pair format, and populated with the following data types.

```json
{
  token : string; // conduit token from AlphaX Cloud
  networkId : string; // unique identifier on the network
  timestamp : integer; // 13 digit UTC timestamp
  data : array of objects // array of objects as defined below
}
```

#### Formatting the Data Array

The data array should be an array of Objects that are configured in the following key:value pair format:

```json
data: [
 {
  channelId : integer; // the channel identifier for the value
  value : number; // the value of the data (16 digit maximum length)
  }
 ]
```

```json
{
 "token": "5b131223c67e7abcd81b0617",
 "networkId": "70B3D32111BD648F7",
 "timestamp": 1660962091000,
