What is CSR (Certificate Signing Request)?
CSR is required in the process of obtaining a Cryptographic Stamp Identifier (CSID) for a device/ EGS unit. CSID is used to uniquely identify an EGS unit associated with a taxpayer for the purpose of stamping (technically cryptographically signing) Simplified Invoices (B2C) and for accessing the Reporting and Clearance APIs.
A CSR includes information such as common name, organization, Value Added Tax (VAT) number, country, etc. The ZATCA Certificate Authority (CA) will use these details while creating a CSID. It also contains the public key that will be included in your CSID and is signed with the corresponding private key.
You must submit CSR from the EGS unit as part of the first-time onboarding of the device or during the renewal of a device. Your EGS unit must submit CSR to the e-invoicing platform after entering the OTP. The CSR is an encoded text that the EGS units submit to the e-invoicing platform and the ZATCA.
