Appian S3 UI File Upload Component

Overview This plug-in allows users to directly upload files to Amazon S3, bypassing the Appian Knowledge Center. It contains a file upload component that allows users to upload any file, regardless of size, to an S3 bucket (the current Appian Amazon S3 plug-in allows for the upload of files to S3 if the file is less than the 1GB Appian limit). The plug-in requires AWS Cognito credentials to authenticate, so an Identity Pool must be configured in AWS prior to using this plug-in. See screenshots and README file for necessary S3 bucket policy and CORS configurations.

Prerequisites: AWS S3 Bucket Management - min version v1.12.3* Amazon Cognito Identity Pool Amazon S3 Bucket *Note: AWS S3 Bucket Management v1.12.3 contains the new logic for Amazon Cognito Authentication, so the S3 UI File Upload Component plug-in will not work if it has not already been installed.
