Build a Slack app using message event subscription

[utsang]

I was basically following video tutorial: https://www.youtube.com/watch?v=6gHvqXrfjuo&t=1030s
everything was working but until I started getting this error.

Following is the code:

env_path = Path('.')/ '.env'
load_dotenv(dotenv_path=env_path)


app = Flask(__name__)
slack_event_adapter = SlackEventAdapter(os.environ['SIGNING_SECRET'],'/slack/events',app)


client = slack.WebClient(token=os.getenv("SLACK_TOKEN"))


@slack_event_adapter.on('message')
def message(payload):
    event = payload.get('event', {})
    channel_id = event.get('chanel')
    user_id = event.get('user')
    text = event.get('text')
    client.chat_postMessage(channel=channel_id, text = text)

if __name__ == "__main__":
    app.run(debug=True)

[seratch]

channel_id = event.get('chanel')

This part is not correct. The key should be “channel”, not “chanel”.

[utsang]

channel_id = event.get('chanel')

This part is not correct. The key should be “channel”, not “chanel”.

Oh thank you very much can't belive I missed that, I had another issue with slack api, this is more of a logic issue: I have the following code:

Hello Everyone,
I am currently making a slack bot that can take ticker name of a certain stock from slack and output its information from yfinance. I have the following code:

client = slack.WebClient(token=os.getenv("SLACK_TOKEN"))
BOT_ID = client.api_call("auth.test")['user_id']

@slack_event_adapter.on('message')
def message(payload):
    event = payload.get('event', {})
    channel_id = event.get('channel')
    user_id = event.get('user')
    text = event.get('text')
    today = date.today()
    d4 = today.strftime("%Y-%m-%d")
    print(d4)

    tickerWant = text
    data = yf.download(tickerWant, start="2021-09-5", end=d4)

    data.to_csv(rf'C:\work\demo\data\{tickerWant}.csv')
   
    # if BOT_ID != user_id:
    #     client.chat_postMessage(channel=channel_id, text = 'print succesful')

so at first the code after tickerWant was in a different file, my understanding was that I could do from chart import message(chart.py is the main python that I had defined message into) that didn't work as I didn't know what to put in the payload argument. I have this code now in the main py file. The issue I am having currently is that once I get the csv file printed to my local storage, I want my code to post successful print to the slack message channel. As of now, it will only do that once I kill the program and if I use client.chat_postMessage() without the if statement with the botID then I repeatedly get the issue of me getting print successful in succession to my slack channel, I dont want that I only want it once its printed. This is an logic error that I don't know how to solve any help would be appreciated.

posting a message several times

Your app might not be responding to requests from Slack within 3 seconds. If so, that can be one of the reasons that your app prints several times. In this scenario, your app receives the same request three times at maximum. For this reason, python-slack-events-api is not recommended for complex apps. Refer to slackapi/python-slack-events-api#84 (comment) for more details. Instead, we recommend using bolt-python; with this library, running time-consuming code in your listener is much easier. You can find many examples here: https://github.com/slackapi/bolt-python/tree/main/examples

if BOT_ID != user_id:

If you go with bolt-python, this if statement is no longer necessary. bolt-python framework automatically ignores the app itself's events for you.

I think that I've answered all your questions here. Would you mind closing this issue now?

Also, if you continue your app development with bolt-python, please feel free to ask questions here: https://github.com/slackapi/bolt-python/issues/new/choose

thank you

Hi, I have similar code but it is correct. I can't connect my ngrok to flask, but it connects to the url request in slack api website.
