API Google Oauth

Is there a way to authenticate to the talks api using google oauth if so, whats the code snippet for it (python)
If there isnt, does the free version authenticate the api ?
Because this isnt letting me in with the my free username and password.
import requests
url = "https://api.d-id.com/talks"
payload = {
"source_url": "https://d-id-public-bucket.s3.us-west-2.amazonaws.com/alice.jpg",
"script": {
"type": "text",
"subtitles": "false",
"provider": {
"type": "microsoft",
"voice_id": "Sara"
},
"input": "Making videos is easy with D-ID"
},
"config": {
"fluent": "false",
"pad_audio": "0.0"
}
}
headers = {
"accept": "application/json",
"content-type": "application/json",
"authorization": "Basic bXN0MTk3NEBzYmNnbG9iYWwubmV0OlNhbHpidXJnMTYwIQ=="
}
response = requests.post(url, json=payload, headers=headers)
print(response.text)
