Updating repositories in Azure Devops with PAT token through Python

Question

I am trying to disable a repo in Azure Devops through the API and I am having trouble authenticating to my Azure devops organization. I have the request correct but I keep getting a

401 client error Unauthorized for URL

I have a PAT token to authenticate, I am just not sure how to add that into the request body to be able to authenticate to Azure Devops. Below is the code that I am using to complete this. I have looked through all the documentation and I cannot find the syntax to complete this but I know a PAT token can be used to authenticate.

print("Would you like to Disable this repository in Azure Devops?")
disable = input("please select y/n: ")
if disable == 'y':
    pat = 'example'
    authorization = str(base64.b64encode(bytes(':' + pat, 'ascii')), 'ascii')
    headers = {
        'Authorization': 'basic '+authorization
    }
    organization = "exmaple"
    disable_payload = '{"isDisabled": true }'
    disable_url = requests.patch(f"https://dev.azure.com/{organization}/{project}/_apis/git/repositories/{i}?api-version=7.1-preview.1",
                                 data=disable_payload)
    disable_url.raise_for_status()
    print("Repo has been disabled")
