Telegram – Telethon get topic id and send message to topic

I have a group with forums in telegram. I need to create new topics from the bot (this is done), and also need to be able to then send messages to these topics at the right events. There was a problem getting the topic_id (it would be nice if you told me how to get it), but let’s skip this, I’ll save it when creating it.

How do I send messages in a channel in the right topic using Telethon (Python, bot)?

I tried getting all the topics, but this API is not available from the bot (to get topic_id)

    To send messages to specific topics in a Telegram channel using Telethon (Python bot), you can follow these steps:

    Create a New Topic (if not already done):

    Use your bot to create a new topic in the channel. Store the topic_id obtained from the creation process for future use.
    Send Messages to the Topic:

    Once you have the topic_id, you can send messages to this topic using Telethon.
    Here’s a basic outline of how you can achieve this programmatically with Telethon:

    from telethon.sync import TelegramClient, events, types

# Replace these with your own values
api_id = 'your_api_id'
api_hash = 'your_api_hash'
bot_token = 'your_bot_token'
channel_username = 'your_channel_username'
topic_id = 'your_topic_id'

# Initialize the Telegram client
client = TelegramClient('session_name', api_id, api_hash)

async def send_message_to_topic(message):
    async with client:
        # Send message to the specified topic in the channel
        await client.send_message(channel_username, message, link_preview=False, silent=True, reply_to=types.InputMessageReplyTo(topic_id=topic_id))

# Replace 'your_message' with the actual message content you want to send
message_to_send = 'your_message'

# Run the function to send the message
client.loop.run_until_complete(send_message_to_topic(message_to_send))

    Explanation:
    API Credentials: Replace ‘your_api_id’, ‘your_api_hash’, and ‘your_bot_token’ with your actual Telegram API credentials and bot token.
    Channel Username: Replace ‘your_channel_username’ with the username of your Telegram channel (e.g., @your_channel_name).
    Topic ID: Replace ‘your_topic_id’ with the topic_id obtained when creating the topic. You’ll need to store and retrieve this ID in your application logic.
    Notes:
    Ensure your bot has the necessary permissions to send messages in the channel and to access the topics.
    The Telethon library allows you to interact with Telegram’s API programmatically, handling authentication and message sending operations.
    Adjust the message content and other parameters (link_preview, silent, etc.) as per your specific requirements.
    By following these steps and using Telethon, you should be able to send messages to specific topics within your Telegram channel effectively.

    Navigating Telegram bot functionalities for managing topics and sending messages can be nuanced. While retrieving topic IDs directly through the bot’s API might not be feasible, ensuring you save them upon creation is pivotal for seamless messaging.

    To send targeted messages to specific topics using Telethon in Python, follow these steps:

    Save Topic IDs: Capture and store topic IDs during their creation using your bot. This manual step ensures you have the necessary identifiers for future message targeting.

    Sending Messages: Utilize the saved topic IDs to direct messages accurately. Here’s a practical approach using Telethon:

    python
    Copy code

    from telethon import TelegramClient

# Configure your Telethon client
api_id = 'your_api_id'
api_hash = 'your_api_hash'
bot_token = 'your_bot_token'

# Initialize Telegram client
client = TelegramClient('session_name', api_id, api_hash).start(bot_token=bot_token)

async def send_message_to_topic(topic_id, message):
    try:
        await client.send_message('your_channel_username', message, link_preview=False, reply_to=topic_id)
        print(f"Message successfully sent to topic {topic_id}!")
    except Exception as e:
        print(f"Error sending message: {e}")

# Replace 'your_channel_username' with your actual channel username
# Replace 'your_saved_topic_id' with the actual topic ID you saved

topic_id = 'your_saved_topic_id'
message_to_send = "Your message goes here."

# Send the message
client.loop.run_until_complete(send_message_to_topic(topic_id, message_to_send))

    For detailed implementation and further guidance, refer to the Telethon documentation.
