do the three pdfs at the zatca portal include all the requirements and everything you need to know to integrate with zatca phase 1 and 2?
i looked everywhere but all i found was scattered info here and there, nothing official that states “this is all you need to know to get started until you comply successfully”
here’s the portal link i am talking about:
