Worked, How do I get PIH (previous invoice hash)?

[sudo-sand]

I have pretty much the same example as you. When I run checkInvoiceCompliance or reportInvoice I get Request failed with status code 400.

One more question, do I store PIH in a DB or how do you get it?

The 400 Failure with reportInvoice is expected. ZATCA's sandbox report API is not fully ready yet. Currently they're returning a constant production cert that does not have the ability to sign Simplified Tax Invoices. Hopefully they fix that soon.

Yes, you will have to store the last invoice hash as a PIH somewhere whenever you create an invoice.

So, with the first phase, I have to store the xml invoices correct?

ZATCA's first phase does not require you to store any XMLs. But yes, for the second phase you will need to store the invoices as a custom object and then generate an XML every time. Or just store the signed XML for each invoice.

Sorry for bothering you, in the first phase, what format does the invoice take?

This package is intended for phase 2. Try something like @mrsool/zatca for phase 1.
