I’m new to both Zoom APIs and Python, and I’m running into an issue that I hope is easy to resolve. I am attempting to loop through all meetings to pull back some data. By using the sample code in the API documentation, I have been able to pull back the first page of data, including the value for next\_page\_token. However, I am stuck at trying to use next\_page\_token in order to return any more data.

What returns is:

{‘code’: 300, ‘message’: ‘The next page token is invalid or expired.’}

I know I’m missing something basic, but I don’t know what it is, and I’m stuck. Any advice would be appreciated.

conn.request(“GET”, “/v2/metrics/meetings?page\_size=2&to=2020-06-02&from=2020-05-01&type=past”, headers=headers)  
res = conn.getresponse()  
data = res.read()  
dataStr = data.decode(“utf-8”)  
response\_obj = json.loads(dataStr)

for x in response\_obj[‘meetings’]:  
print(x[‘email’])

strNextToken = response\_obj[‘next\_page\_token’]  
print(strNextToken)

# I know this should be a loop, but at this point I can’t even get one more page of data…

if strNextToken:  
conn.request(“GET”, “/v2/metrics/meetings?from=2020-05-01&next\_page\_token=strNextToken&page\_size=30&to=2020-06-02&type=past”, headers=headers)  
res = conn.getresponse()  
data = res.read()  
dataStr = data.decode(“utf-8”)  
response\_obj = json.loads(dataStr)  
#print(data.decode(“utf-8”))  
print(response\_obj)

else:  
print(“No Next Page Token”)

Hey @lsteve,

Do you have logs of what you are passing in for the next page token? If you share your next page token we can debug the issue.

Thanks,  
Tommy
