Send ZATCA Invoice for Clearance
See more ZATCA Examples
Demonstrates how to send a ZATCA invoice for clearance, which is to send the HTTP POST with invoice hash and the signed invoice in base64 format.Chilkat Lianja Downloads

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
// This example will send a POST with HTTP Basic Authentication to
// https://gw-fatoora.zatca.sa/e-invoicing/simulation/invoices/clearance/single
// NOTE: At the time of this writing, I don't know for sure if the above URL is correct.
//
// The body of the POST will contain JSON formatted as such:
// {
// "summary": "Standard Invoice",
// "value": {
// "invoiceHash": "PEx8bNFcEMEpHzUVvQntQI6ot8eFqTT/l59b+H1HqX4=",
// "uuid": "16e78469-64af-406d-9cfd-895e724198f0",
// "invoice": "PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz4KPEl....."
// }
// }
// The above JSON is created from the signed XML invoice, such as the following:
// *** Look at the above base64 data for the invoiceHash and uuid. These values are found in the invoice as shown below.
// *** We'll write code to load the signed invoice into a Chilkat XML object, grab the invoice hash and the uuid,
// *** and then construct the above JSON, which will then be sent in a POST. (See below...)
