Adding Telegram Group Members to Your Groups Using Telethon

In the previous Telethon tutorial you learned how to send messages to Telegram group members. Now you are going to learn how to add new members to your own group. We will read the member list from the csv file which we extracted in the previous tutorial and add them to our group.

Make sure to check our previous Telethon tutorials to understand the basics of using Telethon and Telegram API.

The first steps are going to be very similar to the previous tutorials. Basically you need to get API keys from telegram and install Telethon using pip.

So let’s get started.

 

Disclaimer: Telegram does not allow adding more than 200 members to a group or channel by one account. Using this script, I am able to add around 150-200 members with 60 second sleep between each add; after that, you have to change to another Telegram account/number.

Get Telegram API Key

As stated in the previous tutorial you need to get your Telegram API credentials to be able to use the API. So do not hesitate and check the previous tutorial and use the guide to get your own Telegram API credentials, or simply follow these steps:

• Sign up for Telegram using any application.
• Log in to your Telegram core: https://my.telegram.org.
• Go to ‘API development tools’ and fill out the form.
• You will get basic addresses as well as the api_id and api_hash parameters required for user authorization.

 

Install Telethon 

Also you need to install Telethon using pip.

Note: If you are on Linux or Mac, you might need to use sudo before pip to avoid permissions issues.

 

Create Client Object and Login

As usual we have to create  a Telegram client object and check if it is already authorized otherwise ask for an OTP password.

Create a client object.

Note: For the sake of simplicity we are importing  TelegramClient from telethon.sync module.

 

Next, you have to connect the client and check if it is already authorized, otherwise Telegram will send an OTP password to the client and we will ask the user to enter the code which they received.

 

Read Members from CSV File

We are passing the file name in the sys.argv parameters. sys.argv is a list in Python, which contains the command-line arguments passed to the script.

So if you run python sendMessage.py users.csv in the command line  sys.argv will return a list like this:

As you can see, the first item in the list is the name of the script and the second item is the name of our CSV file. So we can access the file name with  sys.argv[1] .

Now you have the name (or path) of our CSV file and you can use Python’s csv module to read the file and create a list of users.

 

Import the required modules

 

Create a dictionary for every user and append that to our user list.

Note: You need to cast the user id and access hash to integer type.

Note: We skip the first row in the CSV file (header) using the  next function.

 

Choose a Group to Add Members

In this step, you are going to ask the user to select a group which they want to add the members to it.

First get all groups using  GetDialogsRequest .

 

Add only super groups to  groups list.

 

Now print all of the groups on screen with their indexes and ask the user to enter the group index they want.

 

Ask for input and get the group using entered index.

 

Get the group entity.

 

Ask User to Enter the Adding Mode

For adding the user we need to get the user entity first. There is two options to do this.

First let’s ask the user which mode they want and then we will explain them one by one.

 

1- By username

Basically you can get any entity in Telethon including users, channels or groups using its username. But as I mentioned before not every user has a username.  So if this mode is selected by user we will skip the users which don’t have a user name while adding. Here is how you can get the user entity by its username.

 

2- By Id and access hash

Every entity in Telegram has an ID and an access hash. The ID is unique but the access hash is different for every telegram account. It means if you scrape the users with an account and you want to add them using another account then you can’t use this mode.

 

Add Members to the Selected Group

Now you have the users in  users  list and the selected group in  target_group . We will use  InviteToChannelRequest function to the add a user to the group. So let’s import it first.

 

Then you need to get the user based on the entered mode (i.e by ID or by user name.

 

Handle Exceptions

Now you can start adding the users but you have to consider some error scenarios.

 

1- PeerFloodError

If you put too much requests on Telegram API or commit tasks very fast, you will get  PeerFloodError . So you need to put a waiting time between each add to prevent this error. We will use 60 seconds in this tutorial to stay safe. But you can play with this number and find the optimum value.

You can also use the random library’s randrange() method giving a random sleep time, say between 60 and 180 seconds. For the sake for clarification, the code below users “print”, but you can of course delete it.

 

2- UserPrivacyRestrictedError

You might get this error for some users depending on their privacy settings.

Finally, let’s add our new members.

 

3. FloodWaitError

If you get this error, you should either wait for the stated time or use another Telegram number.

telethon.errors.rpcerrorlist.FloodWaitError: A wait of 58593 seconds is required
(caused by SendCodeRequest)

So you must avoid this error in the first place. To do so, it is recommended to give an extra sleep time (15 minutes or more) after adding every 50 users. If this will take much time, you can use a cloud server to run your code.

To get a general idea about how this works, run this simple code. Here, you have a list of names; the code loops over names, sleep for 5 seconds after each 10 names, and print the name.

 

As I mentioned earlier, Telegram does not allow adding more than 200 members to a group or channel by one account. Using this script, I am able to add around 150-200 members with 60 second sleep between each add; after that, you have to change to another Telegram account/number.

    1. Hi Sadiq! Have you added your file name to your CMD command?

      Check the part of the tutorial under “Read Members from CSV File”. So you have to pass the file name (and path) to the Terminal/CMD command.

      Otherwise, you can replace “input_file” with your CSV file path directly, line #24 of the code. In this case, delete the line “sys.argv[1]” from you code.

        1. If you will use the Command Prompt to run your Python file, do not change the code at all, just type:
          python sendMessage.py users.csv

          This will work if your files are in the current folder; otherwise, change the path, for example:
          python C:\Users\BijoRino\Desktop\sendMessage.py C:\Users\BijoRino\Desktop\users.csv

    1. Yes, this will not work. You should add the path between quotes. Also, the path here is missing the file name. What can work for example:

      with open("C:\Users\BijoRino\Desktop\users.csv", encoding='UTF-8') as f:

      So here, I have added the CSV file name to the path and made the path enclosed by “quotes”.

      I hope this helps. Please let me know.

    1. You can instead set the file name explicitly in the code. So, instead of:
      input_file = sys.argv[1]
      You can have the file path between quotes like:
      input_file = “c://foldername/users.csv”
