Hi,

I currently face a weird request. I want to add a button to download files from an external REST API. For some specific reasons I must not calls the service from client side. So I'm trying to use an Plugin registered on a custom action and then call the custom action in JavaScript web resource. My question is how to return a binary from custom action? Did any one face the same need and can help me?

May be my approach isn't the best. Any proposal will be welcome.

Emre,

Your solution fits well what I need. I try it with FileSaver.js, and I can download my files.

Thank you for your help.

Hi,

I think you should convert your file to Base64 and return as "string" output parameter from custom action.

At clientside, you can use FileSaver.js (github.com/.../FileSaver.js)
