Python - Value Error on REST Api call using requests

Question

I am trying to check my video upload to vimeo in Python but I keep getting the error:

ValueError: HTTP request does not contain valid JSON data

I have it working in postman with the the same headers and body set to none. This is what I get returned in postman:

{
    "uri": "/videos/*********",
    "upload": {
        "status": "complete"
    },
    "transcode": {
        "status": "complete"
    }
}

This is the link to the Vimeo Api request documentation:

https://developer.vimeo.com/api/upload/videos#table-3

This is what I am working with (Token is my bearer token and videoCode is the video id of Vimeo - sorry can't disclose those as their are from a client), request_url same as in postman, as are the headers.

payload = {}

json_object = json.dumps(payload)

def checkVimeoStatus(videoCode):
    request_url = f"https://api.vimeo.com/videos/{videoCode}?fields=uri,upload.status,transcode.status"
    headers = {'Authorization' : token, 'Connection': 'keep-alive', 'Accept' : '*/*', 'Accept-Encoding': 'gzip, deflate'}    
    response = requests.post(request_url, data=json_object, headers=headers)
    response.raise_for_status()
    results = response.json()
    return results

status = checkVimeoStatus(videoCode)

what am I doing wrong here, adding fake data does not seem to help as setting data=none as well? thanks for the help

requests will JSON-encode data for you when you use the json=... parameter ( see ), you don't need json.dumps() .

But you should set the Content-Type header. And you should use function parameters instead of global variables.

def checkVimeoStatus(videoCode, payload):
    response = requests.post(
        f'https://api.vimeo.com/videos/{videoCode}?fields=uri,upload.status,transcode.status',
        headers={
            'Authorization' : token,
            'Connection': 'keep-alive',
            'Accept' : '*/*',
            'Accept-Encoding': 'gzip, deflate',
            'Content-Type': 'application/json'
        },
        json=payload
    )
    response.raise_for_status()
    return response.json()

status = checkVimeoStatus(videoCode, {})

Depending on what the Vimeo API expects here, you might have to send a little more than {} . Also I doubt that Connection: keep-alive is useful here, and if you expect a JSON response, Accept: */* should be Accept: application/json .
