How can I get the IDs of the keywords available in Neticle?

To get all the keywords that are set up in the system, you should initiate a query to https://data.neticle.com/22.09/keywords based on the documentation: https://data.neticle.com/docs/22.09#keywords:listing-keywords.

In the response JSON you will find all the available keywords in an array with their details (color, name, label) including the ID that should be used for getting the mentions for one or multiple ones.
