How to use Power BI Rest API to export the Power BI Report in PDF format

For Fabric I created a short python script to be ran as a notebook. It uses the great description from this article (Kudos Anonymous) to download the paginated report in the specified format into the onelake: 

def download_paginated_report(group_id:str, report_id:str, file_format:str="PDF", target_path="/lakehouse/default/Files/report.pdf"):
    import requests
    import json
    import time

    token = mssparkutils.credentials.getToken('pbi')
    headers = {
        'Authorization': f'Bearer {token}',
        'Content-type': 'application/json'
    }

    payload = {
    "format": file_format
    }

    url = f"https://api.powerbi.com/v1.0/myorg/groups/{group_id}/reports/{report_id}/ExportTo"

    response = requests.post(url, data=json.dumps(payload), headers=headers)

    export_id = response.json()["id"]

    timeout = 30
    counter = 0
    wait_time = 5
    while True:
        url = f"https://api.powerbi.com/v1.0/myorg/groups/{group_id}/reports/{report_id}/exports/{export_id}"
        response = requests.get(url, headers=headers)
        if response.json()["status"] == "Succeeded":
            break
        if counter > timeout:
            raise(TimeoutError("Request time out"))
        counter = counter + wait_time
        time.sleep(wait_time)

    url = f"https://api.powerbi.com/v1.0/myorg/groups/{group_id}/reports/{report_id}/exports/{export_id}/file"

    r = requests.get(url, headers=headers)
    r.raise_for_status()

    with open(target_path, 'wb') as f:
        f.write(r.content)
    print(f"export saved as {target_path}")


download_paginated_report(group_id="eba40459-c146-4ea9-959e-d3f2dec00973", report_id="bcad0ddb-40fb-43b8-9fbb-c70f4164fcaf")
