Answer 1

Base on the Slack API file.upload documentation What you need to have are:

• Token : Authentication token bearing required scopes.
• Channel ID : Channel to upload the file
• File : File to upload

Here is the sample code. I am using WebClient method in @slack/web-api package to upload it in slack channel.

import { createReadStream } from 'fs';
import { WebClient } from '@slack/web-api';

const token = 'token'
const channelId = 'channelID'
const web = new WebClient(token);

const uploadFileToSlack = async () => {
   await web.files.upload({
     filename: 'fileName',
     file: createReadStream('path/file'),
     channels: channelId,
   });
}

Sending files through http requires a bit more extra work than sending other data. You have to set content type and fetch the file and all that, so you can't just include it in the payload parameter in requests.

You have to give your file information to the files parameter of the .post method so that it can add all the file transfer information to the request.

my_file = {
  'file' : ('/tmp/myfile.pdf', open('/tmp/myfile.pdf', 'rb'), 'pdf')
}

payload={
  "filename":"myfile.pdf", 
  "token":token, 
  "channels":['#random'], 
}

r = requests.post("https://slack.com/api/files.upload", params=payload, files=my_file)
