Connecting the output of the Google Authenticator Node into a own Python based KNIME Node

[Vits]

Hello,

I‘m trying to create a new Python based KNIME Node with this documentation. Create a New Python based KNIME Extension

My goal is to connect the output port from the Google Authenticator Node (Extension: KNIME Google Connectors) into my new node as an input.
I was wondering if there is any way to build an input port so I can use the credentials a user gets from the Google Authenticator Node.
I tried using a custom port object without any luck so far. (Create a New Python based KNIME Extension)

Best regards

Hello @Vits,

It’s great that you’re developing Python-based KNIME extensions. I hope this is just the beginning of a new node series.

Currently, it is possible to connect to the Google Authenticator output port by adding and input port with the type “Credentials” to the one that you are creating

@knext.input_port(
    name="port-name",
    description="port-description",
    port_type=knext.PortType.CREDENTIAL,
)

Then, in the execution method of the node, it is possible to access the PortObject and “extract” the access token generated by the Google Authenticator node, something similar to this.

access_token = knext.PortObject.spec.auth_parameters

If you have any other question regarding this topic please let us now.

Have a nice day
