Welcome to the RingCentral Community

This is an example to read the call log from the beginning of May 21, and write the record to a .CSV file.

fileName = "callrecords.csv"
file = open(fileName,'w')
header = 'id,sessionId,startTime,duration,type,direction,action,result,to_name,from_name,transport'
file.write(header)
file.close()

def read_call_log():
    params = {
        'dateFrom': '2021-05-01T00:00:00.000Z',
        'perPage': 1000,
        'view': 'Detailed'
        }

    resp = platform.get('/restapi/v1.0/account/~/call-log', params)
    write_call_records(resp)

def write_call_records(response
    file = open(fileName,'a')
    jsonObj = response.json()
    for record in jsonObj.records:
        line = "\r\n"
        line += record.id + ','
        line += record.sessionId + ','
        line += record.startTime + ','
        line += str(record.duration) + ','
        line += record.type + ','
        line += record.direction + ','
        line += record.action + ','
        line += record.result + ','

        if record.to != None:
            if "name" in record.to:
                line += record.to.name + ','
            else:
                line += 'null,'
        else:
            line += 'null,'

        if record.from != None:
            if record.from.name != None:
                line += record.from.name + ','
            else:
                line += 'null,'
        else:
            line += 'null,'

        line += record.transport

        # add to your CRM  or other db
        # for demo, I write to a file
        file.write(line)
    file.close()

@Phong Vu Can you please also help me with a sample code which is processing the api response for call-logs for python

Apologies for moving you back and forth between the Developer and Customer community.

Because you wrote "password for production app". Well, app does not have a password so I thought that you meant resetting a user password on production.

Anyway, after moving your app to production, first, you have to change the app production credentials (client id and secret) in your code. Then you have to login with user credentials (username and password) of a user under your production account.
