Amazon S3 provides a simple web-services interface that can be used to store and retrieve any amount of data, at any time, from anywhere on the web. It gives any developer access to the same highly scalable, reliable, secure, fast, inexpensive infrastructure that Amazon uses to run its own global network of web sites. The service aims to maximize benefits of scale and to pass those benefits on to developers. Learn more here: Amazon S3’s Website

Keep in mind although we have NO public access, the security we setup previously will allow the cart to access and provide the file to users that purchase your download.

Adding/Uploading a File

1. Navigate to your bucket by clicking the bucket name in the list of buckets. If you just created the bucket then you are already there.
2. Click the Upload button (do not create a folder for WP EasyCart files, this may cause issues on the product setup side in EasyCart).
   
3. Click Add Files and select the files you wish to upload. Once you add those files, just click next.
   
4. Set Permissions – You do not need to do anything here, the default settings are correct! The Owner should have read/write permissions and public permissions are set to ‘Do not grant public read access to this object(s) (Recommended)’. This is important so that the public does not access your files without first purchasing. EasyCart uses your security credentials to provide access to the appropriate files after purchase.
5. Set Properties – This is up to you, but standard and none should be fine and click next to continue.
6. Review – Click upload if you are happy with the settings.

That’s it! Now your uploads will be available for you to choose in the product setup. Read more below to see how to make the connection.

Setting Up a Downloadable Product

You can create or edit any product and navigate to the ‘Download Options’ section. In this section, choose Download Product, Download Location is Amazon S3, and you can choose any file from the S3 File box that is in the bucket you have setup. If your setup is wrong, it will have an error in this area and you will need to correct the setup to fix this issue.
