Get Slack bot tokens after invoking manifest API?

[nyavramov]

Hey there,

I'm creating a Slack bot that runs on AWS Lambda and I'd like to automate the process of setting up the bot.

To create the AWS resources the bot will run on, I'm using AWS SAM templates to create a Lambda function and an API gateway. Then I'm using the new Slack manifest API to automate the creation of the app within Slack itself.

In python, I was able to define a manifest for my Slack app:

manifest = {
    "display_information": {
        "name": "",
        "description": "...",
        "background_color": #fff,
    },
    "features": {"bot_user": {"display_name": "", "always_online": True}, "slash_commands": [
        {
            "command": "/my_command",
            "url": "https://www.my_url.com",
            "description": f"...",
            "should_escape": True,
        }
    ]},
    "oauth_config": {
        "scopes": {
            "bot": [
                "commands",
                "channels:history",
                "chat:write",
                "groups:history",
                "incoming-webhook",
            ]
        }
    },
    "settings": {
        "interactivity": {"is_enabled": True, "request_url": "https://www.my_request_url.com"},
        "org_deploy_enabled": True,
        "socket_mode_enabled": False,
        "token_rotation_enabled": False,
    },
}

I was then able to use the manifest API to successfully create the app:

import requests
import os 
import json 

payload = {"token": os.environ["SLACK_TOKEN"], "manifest": json.dumps(manifest)}

r = requests.post(
    url="https://slack.com/api/apps.manifest.create",
    data=payload,
)

I've confirmed that the app appears in the Slack app creation UI. However, my Lambda function needs the bot token for the app I created from the manifest above.

Is there a way I can programmatically get the bot token and update my lambda function?

I want to automate as much of the bot deployment as possible, but I don't know of a good way to put the bot token into my lambda function short of manually logging into the Slack UI itself and copying it from there.

Thanks a bunch!

Hi @nyavramov, thanks for writing in!

Unfortunately... no, there isn't. You have to manually install your app into your Slack workspace to issue a bot token.

However, if your app implements the Slack OAuth flow and stores tokens in your database (say, DynamoDB), your app provisioning process (Slack app config creation + AWS Lambda deployment) won't require any manual operations.

To learn how to implement the OAuth flow, please refer to the following resources:

• https://slack.dev/bolt-python/concepts#authenticating-oauth
• https://slack.dev/python-slack-sdk/oauth/index.html
• https://api.slack.com/authentication/oauth-v2
• https://github.com/slackapi/bolt-python/blob/main/examples/oauth_sqlite3_app.py
• https://github.com/slackapi/python-slack-sdk/blob/main/integration_tests/samples/oauth/oauth_v2.py

I hope this helps!

Wow, quite a bit of material on the oauth flow for me to educate myself on. Thanks a bunch for the answer and those references, @seratch !

I can mark this topic as closed.

Did you find a solution to it ?
