hi @saeed ` can i use same csid and certificate and test` - **NO** 1. Get your invoice data ready. 2. Change the invoice into the format recommended by ZATCA (UBL format). 3. Secure the invoice by using your environment-specific CSID/certificate on the updated file from Step 2 _(this is just for easier understanding)_. 4. Test the invoice within the ZATCA environment. Repeat these steps whenever you switch the ZATCA environment, such as between production, simulation, or sandbox ---
