We are building a site in AEM, the site will have both the satanic and dynamic content. Dynamic content resides in external content management system and can be accessed via REST APIS. The approach we took so far is to create custom components to get the content from external source. So, in our architecture, we will be having a page, that will have multiple custom components, which will then call REST API during rendering time. Is this approach correct? Is there any way to combine those multiple rest calls into one?
