The main DSSClient class¶

The REST API Python client makes it easy to write client programs for the DSS REST API in Python. The REST API Python client is in the dataikuapi Python package.

The client is the entrypoint for many of the capabilities listed in this chapter.

For more details about the two Dataiku packages, see Python APIs, Using the APIs inside of DSS and Using the APIs outside of DSS.

Creating a client from inside DSS¶

To work with the API, a connection needs to be established with DSS, by creating a DSSClient object. Once the connection is established, the DSSClient object serves as the entry point to the other calls.

The Python client can be used from inside DSS. In that case:

It’s preinstalled, you don’t need to do anything
You don’t need to provide any API key, as the API client will automatically inherit connection credentials from the current context

import dataiku

client = dataiku.api_client()

# client is now a DSSClient and can perform all authorized actions.
# For example, list the project keys for which you have access
client.list_project_keys()

Creating a client from outside DSS¶

To work with the API, a connection needs to be established with DSS, by creating a DSSClient object. Once the connection is established, the DSSClient object serves as the entry point to the other calls.

When running outside of DSS, you’ll first need to install the client. For that, simply install it from pip

To use the Python client from outside DSS, simply install it from pip.

pip install dataiku-api-client

This installs the client in the system-wide Python installation, so if you are not using virtualenv, you may need to replace pip by sudo pip.

Note that this will always install the latest version of the API client. You might need to request a version compatible with your version of DSS.

When connecting from the outside world, you need an API key. See Public API Keys for more information on how to create an API key and the associated privileges.

You also need to connect using the base URL of your DSS instance.

import dataikuapi

host = "http://localhost:11200"
apiKey = "some_key"
client = dataikuapi.DSSClient(host, apiKey)

# client is now a DSSClient and can perform all authorized actions.
# For example, list the project keys for which the API key has access
client.list_project_keys()

Disabling SSL certificate check¶

If your DSS has SSL enabled, the package will verify the certificate. In order for this to work, you may need to add the root authority that signed the DSS SSL certificate to your local trust store. Please refer to your OS or Python manual for instructions.

If this is not possible, you can also disable checking the SSL certificate by setting client._session.verify = False
