How to use azure logic app action to download files in browser

I originally created a logic app that would, given a JSON payload, run a stored procedure, transform the results into a CSV table and then email the CSV to a specified email account. Unfortunately requirements changed slightly and instead of emailing the csv they want it to download directly in the browser.

I am unable to get the HTTP response action to tell the browser to download the file using the Content-Disposition header. It looks like this is pulled out of the request by design. Is anyone aware of another action (perhaps a function?) that could be used in place of the HTTP response to get a web browser to download the file rather than returning it as text in the response body?

It does indeed seem to be the case that the Response action doesn't support the Content-Disposition header for some reason. Probably the easiest workround is to proxy the request through a simple HTTP-triggered Azure Function with CORS enabled (or an API on your server) that just fetches the file from the Logic App and then returns it with the Content-Disposition header attached.

NB. Don't rely on <a download="filename"> - most browsers that support the download attribute only respect it for same-origin requests.
