Manage files in an Amazon S3 bucket. With this extension, you can list, download, and delete files. You can also generate a signed URL for downloading a file.
Each configured instance of this extension works with a specific bucket. For multiple buckets, use a configured instance of this extension for each bucket.
Prerequisites
Before using the extension from an API proxy using the ExtensionCallout policy, you must:
Get the access key ID and secret access key for the Amazon S3 bucket you'll be working with.
You'll need these, along with the AWS bucket name and AWS region, to configure this extension.
