React app upload file

Hi I have made a custom form using the react framework app on I have added a file upload field but I can’t seem to figure out how to upload a file to a column in a board. I looked through the API documentation but it doesn’t explain it very well. Do I have to format the file in some way to upload it? Thank you any help is welcome.

Hey Alex,

If this an app available via our apps marketplace? Can you please specify which one using a screenshot? I can’t seem to locate it in the marketplace :pray:
