Hi Martijn,

Where are you using the OAuth token at server-side and for what purpose?

Hi João,

No we are using this OAuth token at the client-side.
Without token, we will have no access to the server.

You have any filters or proxy to check the token?

Yes, at every request to the server there is a gateway that checks the token.

There's no supported platform API to do that, although you can patch the XMLHttpRequest js builtin object to add the token to every request.

Thank you, João for your answer.
The XMLHttpRequest JS is a javascript file we can alter? Where can we find this file, in which module?

XMLHttpRequest is a JS builtin API provided by all modern browsers. Check out more here: https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest

You can't get the instance because every request uses a new instance, but you can get the definition (which is the standard one). So you might try and change the default XMLHttpRequest object.

Hi João,

Thanks for your response. With some help from OutSystems support, we got the requirement solved.
I'm posting the code snippet below for any future developers.

XMLHttpRequest.prototype.realSend = XMLHttpRequest.prototype.send;
var newSend = function(vData) {
    this.setRequestHeader('x-my-custom-header', 'some value');
    this.realSend(vData);
};
XMLHttpRequest.prototype.send = newSend;
