How to get macro's containing Jira issues while calling Confluence rest api?

I am using following Confluence rest API and getting a confluence page:-


The page value provides the HTML page and I get my confluence page through it. But the problem is that the macro’s are not being loaded while other content is being loaded successfully.

Getting blank response in the space where macro’s should be loaded.
Can you suggest how can I get macro’s value inside the page which is being loaded???
