Hi there,
On sandbox (developer edition) i can sign and report standard invoice, with success response.
But i always have an issue on simplified invoice:
X509Certificate (CCSID / PCSID) used for signing is not valid certificate (CCSID / PCSID) for this VAT Registration Number.
I used the same steps for standard invoice, is simplified needs a different steps?
Thanks for reaching out, and welcome to our community.
Please note that the sandbox is to clarify the steps for integration.
To ensure successful onboarding with ZATCA, our recommendation is to carefully review the steps on the educational library shared by the ZATCA site. You can find the link below.
We have 2 environments; our recommendation is to start with the simulation environment and successfully generate PCSID; it’s for test purposes before starting with production, knowing that the steps are the same.
