API - JSON failure : json access blocked

An attempt to use JSON to send a request to the SGP API was blocked by the CORS access protocol: javascript console error:

Access to XMLHttpRequest at ‘http://127.0.0.1:59590/’ …
has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

Is there a way for setting up CORS access policy in SGP?

how are you attempting to send the request? Can you attempt with PostMan or through the page hosted at http://localhost:59590

Thanks,
Jared

Hi Jared,
sorry for the late reply, I am using the localhost http service.

I will post more about this today.
