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.

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)

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.
