Hello,

Yes, you’ll need to complete the settings so that the plugin has your access and secret keys. Without these keys, it cannot upload files to your S3 account. You can set these keys on the global level (Forms –> Settings –> SyncS3), or on the form level under the SyncS3 form settings.

Here’s an article that describes more about the Direct to S3 field. https://elegantmodules.com/direct-to-s3-uploads-with-syncs3/
