The programmatic access works with a POST method to an action, as part of the path to the action includes your Organisation GUID, this can be found in your dcat “@id" key and is the alphanumeric string between “….io/org/” and “/dcat/…” so “28ccd497-7acd-4470-bd17-721d5cbbd6ef” in the example below. Note this is also available in the dcat url and is required when making API calls to datasets
...
A link to your DCAT can be found on a drop-down menu below the logo on your Organisation page, as shown below. (Select ‘Public’ in the menu.)
