Dealing with a 302 response in Power Automate

Posted on by thomas1992UK

Hi,

I want to download a file - when I enter the URL in the browser it downloads.

When I use the HTTP request in power automate is returns a 302 error. I have tried the run after failed option but this returns a another http link as opposed to the body content.

I have attached the flow and a screenshot from power automate.

If I click deal with the 302 redirect response in postman it downloads the file correctly, wondering how to do this in power automate.

hi @thomas1992UK your link is public? Becouse 302 error is when you have headers to redirect the link, so you need to disable redirect headers from your website.

@thomas1992UK mm ok, so in body you need to add the parameter you need to correctly log in. Parameters like this.
client_id=exampleApiKey&client_secret=exampleSecret&username=someUsername&password=WithSomePassword

@thomas1992UK another thing you can do is run after error because as I told you the error is an redirect error so maeby you need someting in you header html page.

Thanks, now I have this bit working.

When I get the body from the HTTP request it returns it like the image (binary?), how do I transform this to a viewable image?

Thanks,
Tom

Please provide the solution to the download rather than just stating "Thanks, now I have this bit working."

I've managed to get it to work for my requirement.

It appears that the request needed to include an "Accept" header in addition to the "content-type" header I already had.

Once I added that header to the request, then it handled the 302 response and returned a 200-OK with the expected body content.
