Hello @rikiya_murakami,
Thank you for raising this question in the Community! You can follow this guide on creating and updating content using the Confluence Cloud REST-API. You would need to create the page first and then update the content. In the content body, you can use the wiki markup example from the Excerpt macro documentation.
You can find additional parameters at the bottom of that page. I'll include the example below.
{excerpt:hidden=true|atlassian-macro-output-type=BLOCK}
This is the *text* I want to reuse in other pages. This text is inside an Excerpt macro.
{excerpt}
I hope that helps, but feel free to raise a question with the Atlassian Developer Community if you need further assistance!
Take care,
Shannon
