Apple Search Ads API - Access Token Unauthorised

I followed the Apple documentation and got my access token. But when I call the below I get an error. Would it be possible to help?

url = https://api.searchads.apple.com/api/v4/acls

resp = requests.get(url)

result = resp.json()

print(result)

Error:

{'data': None, 'pagination': None, 'error': {'errors': [{'messageCode': 'UNAUTHORIZED', 'message': 'Invalid cert. cert null', 'field': ''}]}}

--

url = https://api.searchads.apple.com/api/v4/campaigns

headers = {

      "Authorization": "Bearer {"+access_token+"}",

      "X-AP-Context": "orgId={"+orgId+"}"

}

resp = requests.get(url, headers=headers)

result = resp.json()

print(result)

Error:

{'data': None, 'pagination': None, 'error': {'errors': [{'messageCode': 'UNAUTHORIZED', 'message': 'Invalid token: 5594b1f4-9766-49e1-ba5f-ef5f23111da5', 'field': ''}]}}
