Connect Wasabi

Wasabi is a hot cloud storage service with no egress fees. This guide walks you through connecting your Wasabi bucket to HeftySend.

Custom storage requires a Premium or Ultra plan. See Using your own storage with HeftySend for an overview.

Step 1: Create your Wasabi bucket

  • Go to your Wasabi Console
  • Click "Create Bucket"
  • Enter a unique bucket name
  • Select a region closest to your users
  • Click "Create Bucket"

Step 2: Set up CORS

  • Click on your bucket name to open it
  • Go to the "Settings" tab
  • Find "CORS Configuration" and click "Add CORS rule"
  • Paste this configuration:
[
  {
    "AllowedOrigins": ["*"],
    "AllowedMethods": ["GET", "PUT", "POST", "DELETE", "HEAD"],
    "AllowedHeaders": ["*"],
    "ExposeHeaders": ["ETag"],
    "MaxAgeSeconds": 3000
  }
]
  • Click "Save"

CORS must be configured on the bucket or browser uploads will be blocked.

Step 3: Create access keys

  • Go to Access Keys in your account
  • Click "Create New Access Key"
  • Optionally enter a description (for example, HeftySend)
  • Click "Create"

Download or copy both the Access Key and Secret Key now. They are only shown once.

Step 4: Connect to HeftySend

  1. Go to Settings > Storage in your HeftySend dashboard
  2. Click "Configure S3 Storage"
  3. Enter your endpoint URL based on your region (see table below)
  4. Enter your Access Key and Secret Key
  5. Enter your bucket name
  6. Click "Test Connection" then "Save"
