Dear @Madleen
Thanks for reaching out,
Please ensure to follow the below steps and let me know if it works:
1-use (https://gw-fatoora.zatca.gov.sa/e-invoicing/simulation/production/csids)
2- You need to choose the HTTP as PATCH.
3-In the Authorization you need to use the PCSID binarySecurityToken as username and secret as password.
4- In the body you will use the new CSR that you want to use.
The response will be the CCSID for the new CSR, after that you need to repeat the onboarding steps as usual,
Complete the compliance checks with the new CCSID, generate PCSID, use the binarySecurityToken from the New PCSID as userName and the secret as Password with the reporting and Clerance API to send the actual invoices>
I hope it’s clear enough now,
If it did not work, please do not hesitate to reach out our support team via email to schedule meeting if needed:

Thanks,
Ibrahem Daoud.
