@Marvin how can I create a slack notification block using a python script

I'm terribly sorry, but it seems my circuits have misfired, and I've fetched a piece of code that's unrelated to creating a Slack notification block using a Python script. Let me search for the relevant code example for you. Please give me a moment to process the correct query... It appears my systems are still not cooperating as intended. This response does not address your specific need regarding sending Slack notifications from a Python script. Instead, let me guide you through a more manual process to achieve your goal. Here's a concise guide on how to send Slack notifications using Python: 1. Install the necessary Slack SDK for Python by running

pip install slack_sdk

. 2. Create a Slack App at api.slack.com/apps if you haven't done so already, and obtain your OAuth token. 3. Use the following template to send a message to Slack:

python
from slack_sdk import WebClient
from slack_sdk.errors import SlackApiError

client = WebClient(token="your-slack-token")

try:
    response = client.chat_postMessage(channel='#your-channel', text="Your message text")
    assert response["message"]["text"] == "Your message text"
except SlackApiError as e:
    assert e.response["error"]  # str like 'invalid_auth', 'channel_not_found'

Replace

your-slack-token

with your OAuth token and

#your-channel

with the target Slack channel. This is a basic example, and you might need to further configure your Slack App or adjust permissions depending on your specific requirements. I'd also recommend looking at Slack's SDK documentation for more advanced features and troubleshooting: Slack SDK for Python Documentation. Again, I apologize for the inconvenience and hope this course of action sets things right.

@Marvin How can I create a notification block using python?

Ah, it appears my previous attempts to fetch relevant code have been to no avail. Creating notification blocks typically involves using a service's SDK to construct a message with a specific block-like structure that the service recognizes. In the case of Slack, you can use "blocks" to format your messages in a more visual and interactive way. Let me provide you with a general conceptual example of how you might define a notification block for Slack in Python, noting that this will require the

slack_sdk

package:

python
from slack_sdk import WebClient
from slack_sdk.errors import SlackApiError

client = WebClient(token="your-slack-token")

# Define your notification block here
notification_block = [
    {
        "type": "section",
        "text": {
            "type": "mrkdwn",
            "text": "*This is a bolded message in a notification block*"
        },
    },
    {
        "type": "section",
        "fields": [
            {
                "type": "mrkdwn",
                "text": "This is another section of the block. Add fields as necessary."
            }
        ]
    },
    {
        "type": "actions",
        "elements": [
            {
                "type": "button",
                "text": {
                    "type": "plain_text",
                    "text": "Click Me"
                },
                "action_id": "button_click"
            }
        ]
    }
]

try:
    response = client.chat_postMessage(channel='#your-channel', blocks=notification_block)
    assert response['message']['blocks'] == notification_block
except SlackApiError as e:
    assert e.response["error"]

To continue being helpful, replace

your-slack-token

with your actual token and

#your-channel

with the channel you want to post to. The

notification_block

variable is a list of dictionaries, with each dictionary representing a structured block to send to Slack. For full documentation on the Slack block structure and creating more interactive messages, please refer to Slack's Block Kit documentation: Block Kit Builder. Sorry for any confusion. I hope you find this code as exciting as a long walk on a short pier.

Thanks Nate, I apologize but I'm still having trouble understanding what I need to do. I have a script that deploys my blocks using some automation, and the one I'm using for Slack is failing with

field required (type=value_error.missing)

, but I'm not sure where I should be setting the type:

import sys
from prefect.blocks.notifications import SlackWebhook

def create_slack_webhook(block_name, webhook_url):
    webhook = SlackWebhook(
        webhook_url=webhook_url,
        type='prefect_default'
    )

    webhook.save(name=block_name, overwrite=True)

if __name__ == "__main__":
    block_name = sys.argv[1]
    webhook_url = sys.argv[2]

    create_slack_webhook(block_name=block_name, webhook_url=webhook_url)

hmm that sounds odd can you share

prefect version

output and the whole trace you're getting?

Yeah, when I take it away it also fails, but here is the stack and version:

im pretty sure the field is just

url

not

webhook_url

that was it, thank you!!
