Telegram - Import Members into a Channel

There are two conditions to Import / Export members of a telegram channel.

1) You should be an administrator or owner of the channel, then only you will be able to import or export members.

2) If a member has selected ‘My Contacts’ option in ‘who can add you to groups and channels’ then you should be added in his/her contact list only then you can import him/her in the channel.

To import channel members, First Generate api id and api hash in your telegram account. To do this, open my.telegram.org
Login using your registered phone number.
Now Open Link Development Tools and copy your api id and hash
We will use the api id and hash in the Python Script

 Create virtual environment with python 3 and install Telethon using pip.

virtualenv telegram -p /usr/bin/python3
source telegram/bin/activate
pip install Telethon==1.23.0

Update API ID, API hash, telegram registered phone number and channel username(it can be found on the channel description page) in the following python script import.py.

from telethon.sync import TelegramClient
from telethon.tl.functions.messages import GetDialogsRequest
from telethon.tl.types import InputPeerEmpty, InputPeerChannel, InputPeerUser
from telethon.errors.rpcerrorlist import PeerFloodError, UserPrivacyRestrictedError
from telethon.tl.functions.channels import InviteToChannelRequest
import sys
import csv
import traceback
import time

api_id = 9999999
api_hash = 'zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz'

client = TelegramClient('session_name', api_id, api_hash)
client.start()

channel = client.get_entity('pythonlovers07')
print(channel)

input_file = 'members.csv'
users = []
with open(input_file, encoding='UTF-8') as f:
    rows = csv.reader(f,delimiter=",",lineterminator="\n")
    next(rows, None)
    for row in rows:
        user = {}
        user['username'] = row[0]
        user['id'] = int(row[1])
        user['access_hash'] = int(row[2])
        user['name'] = row[3]
        users.append(user)
        
 
mode = int(input("Enter 1 to add by username or 2 to add by ID: "))

for user in users:
    try:
        print ("Adding {}".format(user['id']))
        if mode == 1:
            if user['username'] == "":
                continue
            user_to_add = client.get_input_entity(user['username'])
            print(user['username'])
        elif mode == 2:
            user_to_add = InputPeerUser(user['id'], user['access_hash'])
        else:
            sys.exit("Invalid Mode Selected. Please Try Again.")
        target_group = 'pythonlovers07'
        target_group_entity = InputPeerChannel(channel.id,channel.access_hash)
        print(target_group_entity)
        print(user_to_add)               
        client(InviteToChannelRequest(target_group_entity,[user_to_add]))
        print("Waiting 60 Seconds...")
        time.sleep(60)
    except PeerFloodError:
        print("Getting Flood Error from telegram. Script is stopping now. Please try again after some time.")
    except UserPrivacyRestrictedError:
        print("The user's privacy settings do not allow you to do this. Skipping.")
    except:
        traceback.print_exc()
        print("Unexpected Error")
        continue

Run the Python script in the same virtual env.

python import.py

members.csv should be in same directory where you are running the script. members.csv has all the exported channel members. 

It will list all your channels. Choose number of the channel into you want to import members. Members will be imported in the channel.
