Procedure ChilkatExample()

    ; This example requires the Chilkat API to have been previously unlocked.
    ; See Global Unlock Sample for sample code.

    ; It is assumed you've already generated a CSR.
    ; Also, you'll need an OTP code, valid for 1 hour, which is generated online in the Fatoora portal.  See 
    ; https://zatca.gov.sa/ar/E-Invoicing/Introduction/Guidelines/Documents/E-invoicing%20Detailed%20Technical%20Guidelines.pdf

    ; Manually replace this with the OTP code you interactively obtained in a browser session from the Fatoora portal.
    ; The OTP code is valid for 1 hour.
    otp.s = "123434"

    ; You should already have a CSR in a file containing something that looks like this:
