Form with Single File Upload Control - Using the Formstack Power Automate Connector/Trigger: Most forms send as base64, some will send a URL like: https://nameofmycorporation.formstack.com/admin/download/file/16964999999

We have some forms with single file upload controls and most forms seem to send base64 in the JSON payload, but we have a form is sending just a URL, example: https://nameofmycorporation.formstack.com/admin/download/file/16964999999

We much prefer base64.

I've looked everywhere and cannot find a setting that toggles this. How do I get back to base64?

Thanks!
