Edit and resend websocket data

Davide | Last updated: Jul 25, 2018 02:46PM UTC

Hello, I'd wish to edit and resend websocket data, like we do for HTTP requests. Is that something doable?

You can intercept WebSockets messages and modify them. However, there isn't a tool like Repeater - although this is something we're likely to add in future.

Hello support, in the last version of burp I see that it is possible to reply websocket with repeater tab. but my problem is that when the websocket connection has been connected but after put a command message it disconnect fast. Also when intercepting the website with burp I can not to login to that because of that problem. I think there is problem when "Send A Message" to websocket. I tested all other tools like ZAP and they connects easily to the game when intercepting, but with burp it couldn't.

Could you update to the latest version (v2.1.02) and let us know if the problem persists.

Hi, I installed the the latest version (v2.1.02) , but the problem still exists. burp WebSocket UI is weak still, and can not connect to some websites when intercepting a website with websocket the connection to website disconnected. In fact it connects to Websocket but after input the right message it disconnect.
