Requests post keep getting 403 erroe

[WNZhao1988]

Hi NDA data access team,

When I tried to use this python code response = requests.post('https://nda.nih.gov/api/package/1184998/files', json=s3Files, headers=headers) in you example code, I got 403 error. But a few months ago, I used the same code and can successfully get access the server. I'm not sure why this happened? Could you help me with this?

Regard,
Naren
