Hi @Tambe great to see you here, I hope you remember me :)

Also I want to know what is this "source" represent in API response (please see attached screenshot), @0xkaywong any idea about this?

@Isaac I am confused regarding one thing:
I want to confirm if the restrictiontype shown in API response (please see attached screenshot) same as user-specific restrictions field in Mediawiki dumps (please see attached screenshot) ?
I searched in API docs and other pages like these (https://www.mediawiki.org/wiki/API:Database_field_and_API_property_associations, https://www.mediawiki.org/wiki/Manual:Page_restrictions_table) to confirm it but couldn't find any info about it, can you please direct me to any resource where I can confirm if they do/don't represent the same thing?
