Restore deleted Telegram messages, medias and files from groups

There's not telegram API method for this, we need to call MTProto methods to retrieve messages from the "Recent Actions" (Admin Log) since deleted messages (and medias) gets moved there for 48 hours before the permanent deletion.

from telethon import TelegramClient, events, sync
from telethon.tl.types import InputChannel, PeerChannel
from telethon.tl.types import Channel
import time

# Get your own api_id and
# api_hash from https://my.telegram.org, under API Development.
#  or from https://tjhorner.dev/webogram/#/login
api_id = API_ID
api_hash = API_HASH

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

group = client.get_entity(PeerChannel(GROUP_CHAT_ID))

#messages = client.get_admin_log(group)

file1 = open("dump.json","w") 
c = 0
m = 0
for event in client.iter_admin_log(group):
    if event.deleted_message:
        print("Dumping message",c, "(", event.old.id, event.old.date,")")
        file1.write(event.old.to_json() + ",") 
        c+=1
        if event.old.media:
            m+=1
            #print(event.old.media.to_dict()['Document']['id'])
            client.download_media(event.old.media, str(event.old.id))
            print(" Dumped media", m)
        time.sleep(0.1)

FAQ

How do I run this?

Please check https://docs.python.org/3/faq/

Here is my attempt at creating a "restore" script. Note that you cannot restore messages with their original date, so this script will send them as brand new messages, and append the original date to the message body. It will also send photo, video, audio, etc. media messages, and stickers correctly.

First of all, you will have to edit the dump.json file, because OP's script does not output valid json format. To fix this, append [ at the beginning, and ] at the end of the file.

Then run this script in the same folder where you ran OP's script. Don't forget to replace the api_id, api_hash and chat_id variables.

import json
import time
import glob
from telethon import TelegramClient
from telethon.tl.types import PeerChat
from datetime import datetime

with open("dump.json","r") as file:
    content = json.load(file)
    # sort by date:
    content = sorted(content, key=lambda x: x["date"])

    api_id = API_ID
    api_hash = API_HASH
    chat_id = GROUP_CHAT_ID

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

    group = client.get_entity(PeerChat(chat_id))

    for msg in content:

        message_id = msg["id"]
        message = msg["message"]
        has_media = msg['media'] != None
        has_message = message != ""
        date = datetime.fromisoformat(msg["date"]).strftime("%Y %b %d, %H:%M")

        # print message, date, and attachment info:
        print(f"{i} {message}, {date}, has_media: {has_media}")

        if (has_message):
            message = str(date) + "\n\n" + str(message)
        else:
            message = str(date)

        did_send_media_msg = False

        if has_media:
            file_names = glob.glob(f"{message_id}.*")
            for file_name in file_names:
                print(f"Sending Media: {file_name}")
                client.send_file(entity=group, file=file_name, caption=message, silent=True)
                did_send_media_msg = True

        elif has_message or (not did_send_media_msg):
            print(f"Sending Message: {message}")
            client.send_message(entity=group, message=message, silent=True)

        # sleep to avoid rate limiting, you may experiment with reducing this time:
        time.sleep(1)

Hello, Can someone help me recover my telegram messages? I can pay!!

Gyus! I've updated code from dJani97

asyncio.run(main())

Added sending message in any case, added async() and just fixed code and now it's working)

@Silenseo hello, can you help with that error?

can you help with that error?

Something happened with your JSON file.
Please look at this point:

To fix this, append [ at the beginning, and ] at the end of the file.

yeah I checked it, no luck. Tried the same on windows and works just fine (except noticed the comma at the end of JSON and removed it maybe that was an issue). Thank you very much, regardless! That helped a lot

Thank you very much, regardless! That helped a lot

You're welcome)

api_id = ''
api_hash = ''
chat_id = ''
I hope these are not real account )

I mangaged to run the code successfully, but nothing is happening after i logged in. what could be wrong?
