API call response - JSON downlading

In your AEM Service - how are you getting the JSON - are you calling another service that returns JSON. Are you then parsing the JSON? Is this a custom service that you created using Java?

Thank for your quick response.

We are writing a servlet and exposing the endpoints. It a custom service created using Java and yes, are are parsing the JSON.

To add further to my question, we get a response when I hit the endpoint Author URL, when I try to hit the same using postman, we don't get any response.

Publish and Localhost URL just download the JSON file.

Thank you

See Arun suggestion.

Also - in a use case we have in an article,  - we make a call to a service that returns JSON. We then parse the JSON and set our Java's data members and then display the data in a HTL component's view. At no point - is the JSON downloaded. See:

Creating an Adobe Experience Manager 6.4 HTL Component that displays data from a Restful Web Service 

Content-Disposition - HTTP | MDN  says  In a regular HTTP response, the Content-Disposition response header is a header indicating if the content is expected to be displayed inline in the browser, that is, as a Web page or as part of a Web page, or as an attachment, that is downloaded and saved locally.

Hence, check the request headers and also check Apache Sling Content Disposition Filter configuration in /system/console/configMgr or it could be somewhere in your code or specific browser behavior.

It worked, Thank you Arun.
