Hi @vsoppa1,

welcome to the Community and thank you for your question!

You can send a post request from your Python script to Ataccama MMM using GraphQL. This example will list all the sources from the catalog:

import requests

session = requests.Session()
session.auth = (user, password)

query="""query {
    sources(versionSelector: {draftVersion: true}) {
        edges {
            node {
                gid
                draftVersion {
                    name
                    description
                }
            }
        }
    }
}"""

r = session.post('https://one.local.ataccama.pro/graphql', json={'query': query})

print(r.status_code)
print(r.text)

This code is the most basic implementation using basic auth (free text as password). You might want have a look at this Library in Python where you can write your own.

In our answer, we are assuming that you are using Ataccama ONE Gen2. 

Hope it helps.
