Upload and Retrieve Data with Viam's Data Client API

The data client API allows you to upload and retrieve data to and from the Viam app.

Support Notice

Data client API methods are only available in the Python SDK.

Establish a connection

To use the Viam data client API, you first need to instantiate a ViamClient and then instantiate a DataClient.

You will also need an API key and API key ID to authenticate your session. To get an API key (and corresponding ID), you have two options:

The following example instantiates a ViamClient, authenticating with an API key, and then instantiates a DataClient:

import asyncio

from viam.rpc.dial import DialOptions, Credentials
from viam.app.viam_client import ViamClient


async def connect() -> ViamClient:
    dial_options = DialOptions(
      credentials=Credentials(
        type="api-key",
        # Replace "<API-KEY>" (including brackets) with your machine's API key
        payload='<API-KEY>',
      ),
      # Replace "<API-KEY-ID>" (including brackets) with your machine's
      # API key ID
      auth_entity='<API-KEY-ID>'
    )
    return await ViamClient.create_from_dial_options(dial_options)


async def main():
    # Make a ViamClient
    viam_client = await connect()
    # Instantiate a DataClient to run data client API methods on
    data_client = viam_client.data_client

    viam_client.close()

if __name__ == '__main__':
    asyncio.run(main())

Once you have instantiated a DataClient, you can run API methods against the DataClient object (named data_client in the examples).
