Друг помог мне, с этим IRL, вот оно:

import requests
import json

output = {'output_urls' : []} 
url = 'https://v2.convertapi.com/convert/pdf/to/jpg?Secret=xxxxxxx' # Hidden
headers = {'content-type': 'application/json'}
payload = {
    'Parameters': [
        {
            'Name': 'File',
            'FileValue': {
                'Url': 'to be populated'
            }
        },
        {
            'Name': 'StoreFile',
            'Value': 'true'
        },

        }
    ]
}

for x in input_data['input_urls'].split(',') : # input_data is passed by Zapier
  if x[-3:] == 'pdf':
    payload['Parameters'][0]['FileValue']['Url'] = x

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

    for file_url in response_obj['Files'] :
      output['output_urls'].append(file_url['Url'])

  elif x[-3:] == 'jpg' or x[-3:] == 'png' or x[-4:] == 'jpeg' :
    output['output_urls'].append(x)

return output
