[GraphQL] Calling GraphQL endpoint programatically from within AEM (OSGi bundles)

[baoyu_li]

Hi All, 

We'd like to make calls to GraphQL endpoint programatically from within AEM (OSGi bundles).

Can help share how to best do it?

Should we use https://github.com/adobe/aem-headless-client-java?  Is this Java client designed to be used inside AEM or outside AEM?

Or what about using HTTP Client Factory in AEM? https://kiransg.com/2021/11/08/aem-invoke-api-how-to-use-http-client-factory/

@baoyu_li you can use GraphiQL Interface to directly input, and test queries (The interface should be installed separately, the interface can be downloaded from Adobe software distribution).

thanks @Bhuwan_B , but we want to call it programatically using Java in AEM.
