Use Cases

🎥

Video of how to integrate the plugin

1. Restrict access to the bucket (allows access only to application visitors).

❗

Restricting access to a specific HTTP referer Suppose that you have a website with a domain name (www.example.com or example.com) with links to photos and videos stored in your Wasabi bucket, YOUR_WEB_SITE_FULL_URL. By default, all the Wasabi resources are private, so only the account that created the resources can access them. To allow read access to these objects from your website, you can add a bucket policy that allows permission with a condition, that the get request must originate from specific web pages.

Go to your Wasabi console

2. Go to bucket settings

3. Go to tab "POLICIES"

4. Add code to this area

javascript
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "s3:*",
      "Resource": "*",
      "Condition": {
        "StringLike": {
          "aws:Referer": "YOUR_WEB_SITE_FULL_URL"
        }
      }
    }
  ]
}

And Save

2. Restrict access to the bucket (deny access to all except the application visitors).

You can make your files private only for those who are trying to access them through a Bubble app. In your WASABI account, open your list of buckets and select the one you want to protect. Click in Settings.

Go to the POLICIES tab

Paste the code below

javascript
{
  "Id": "acceptsonlyhttpreferer",
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "Public",
      "Effect": "Deny",
      "Principal": {
        "AWS": "*"
      },
      "Action": "s3:GetObject",
      "Resource": "arn:aws:s3:::YOUR_BUCKET_NAME_HERE/*",
      "Condition": {
        "StringNotLike": {
          "aws:Referer": [
            "https://YOUR_BUBBLE_APP_URL_HERE/",
            "https://YOUR_BUBBLE_APP_URL_HERE/*",
            "https://console.wasabisys.com/",
            "https://console.wasabisys.com/*"
          ]
        }
      }
    }
  ]
}

When all this is set up, your files will be only accessible through

Your Bubble app

WASABI Console

Even if you copy and paste the file URL in your browser, it will not work. It will only work if the click comes from your app or from Wasabi console.

Quick setup

Place element on the page

Setup your element

✅

To correctly configure the fields named Type read the documentation attached to them.

Choose restrictions for uploading files

Change bucket

Customize the file type perceived by the element

✅

A filename extension, file extension, or file type is an identifier specified as a suffix to the name of a computer file. The extension indicates a characteristic of the file contents or its intended use. More Information... Example of Extensions:

.jpg - JPEG has been the most widely used image compression standard in the world.

.psd - Photoshop Document (PSD) is a raster format for storing graphic information using lossless compression, created specifically for Adobe Photoshop and supporting all its capabilities.

.pdf - Portable Document Format (PDF) is a file format developed by Adobe in 1993 to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems.

etc.

Groups of file types:

audio/* -any audio file.

video/* -any video file.

image/* -any image file.

You can allow Auto Submit (Auto upload files to Wasabi after selection) and skip the next steps.

If you do not want the files to be automatically loaded, you need to set up an action for this action.

Check if Auto Submit is disabled ("no")

Add a button or other element to trigger the action

And setup workflow

If Redefine Fields is "no" - workflow setup is finished.

❕

You have the option to change the trash can by reconfiguring the upload endpoint in the action. To do this, specify the value of the field "redefined fields" to yes and specify a new bucket.

Troubleshooting

If you need to create a folder or file with diacritic you need to use text formatted as URL Encoded:
