Use HTTP URL in nodered html page

Hi,
I have developed an html page and I'm using an API hosted on HTTP URL but browser is not letting me call that API is there a way I can bypass this in node-red.

Are you talking about CORS issues? If so, then you can set the CORS headers in the HTTP response node:

Http response node code:

[{"id":"8f6d59d61dc6960a","type":"http response","z":"f93e13e54f881a08","name":"","statusCode":"","headers":{"Access-Control-Request-Method":"POST,GET","Access-Control-Allow-Origin":"*"},"x":988,"y":228,"wires":[]}]

Something like that.
