Question

I’m trying to write a simple script to download call details information from Twilio using the python helper library. So far, it seems that my only option is to use .iter() method to get every call ever made for the subaccount. This could be a very large number.

If I use the .list() resource, it doesn’t seem to give me a page count anywhere, so I don’t know for how long to continue paging to get all calls for the time period. What am I missing?

Here are the docs with code samples:

As mentioned in the comment, the above code did not work because remaining_messages = client.calls.count() always returns 50, making it absolutely useless for paging.

Instead, I ended up just trying next page until it fails, which is fairly hacky. The library should really include numpages in the list resource for paging.

import twilio.rest
import csv

account = <ACCOUNT_SID>
token = <ACCOUNT_TOKEN>

client = twilio.rest.TwilioRestClient(account, token)

csvout = open("calls.csv","wb")
writer = csv.writer(csvout)

current_page = 0
page_size = 50
started_after = "20111208"

test = True

while test:

     try:
         calls_page = client.calls.list(page=current_page, page_size=page_size, started_after=started_after)

         for calls in calls_page:
             writer.writerow( (calls.sid, calls.to, calls.duration, calls.start_time) )

         current_page += 1
     except:
         test = False
