Description
Hello,
need someone who will:
1. connect prestashop invoice creation to status canceled. This is cancellation of the regular invoice generated when order status is creeated. When status cancelled is added to order, new invoice number, with - (minus) near prices and cost, should be generated.

2. When updating status to Shipped invoice is automatically created. We need to create request which must be sent to authorized agency for checking and signing sale on the prestashop webshop (sale authorization). Request must have data from completed purchase sent to the recipient server with digital certification (provided from us) and receiving approval with signature for that sale (approval is just a line of numbers). Of course, this should be without errors.

3. QR Code on the invoice with purchase/payment parameters & received number from GOV agency
When issuing invoices, the person responsible for fiscalization displays QR code on each invoice together with the invoice data It prints the QR code of that invoice so the customer can verify invoice through it. Should be used QR code model 1 or model 2 of the smallest possible version. The QR code should be minimum size of 2 by 2 centimeters, where there must be empty space on all sides of the QR code minimum 2 millimeters. It must not be printed on a picture or logo or contain a picture or logo. QR code should have minimum "L" level error correction. It must comply with the ISO/IEC 15415 standard.
Parameters for QR code:
parameters in the url (just an example):

jir (returned key from gov. site): jir=12345678-1234-1234-1234-123456789012
datv (date & time of the invoice): datv=20200921_0630
amount (total amount): izn=52599

I can provide docs and code example for 2nd task.
This is for prestashop 1.7, so it's PHP, MySQL, XML work.

Thanks!
