A Production CSID is a CSID that is used by the EGS to call the core e-invoicing production APIs such as reporting, clearance, etc. This CSID is generated by ZATCA CA and returned to the EGS which it can use to invoke the aforementioned APIs. Additionally, the Production CSID is added as a request header and also is used to authenticate and authorize the EGS.
