Build a Slack Bot for File Sharing with EasySend API

Build a Slack bot that lets your team upload and share files without leaving Slack. Uses the EasySend API (no authentication needed).

How It Works

1. User types /share report.pdf in Slack
2. Bot uploads the file to EasySend via API
3. Bot posts the share link back to the channel

Implementation (Node.js)

const { App } = require('@slack/bolt');
const FormData = require('form-data');
const fetch = require('node-fetch');

app.command('/share', async ({ command, ack, say }) => {
  await ack();
  // Upload to EasySend
  const form = new FormData();
  form.append('files[]', fileBuffer, filename);
  const res = await fetch('https://easysend.co/api/v1/upload',
    { method: 'POST', body: form });
  const data = await res.json();
  await say('Shared: https://easysend.co' + data.share_url);
});

Why EasySend API for Slack Bots

• No API key needed (zero setup)
• One POST request, one share link
• JSON response with all metadata
