Decode

This endpoint allows for the decoding of a Zapper-supported QR code to retrieve an invoice.

Identifying Zapper-supported QR Codes

Zapper-supported QR codes include Zapper's proprietary QR codes, as well as various third-party provider codes:

• Crest Parking and Access Control

• HUB Parking Technology

• Netcash

• Pay@

• Servest

• SKIDATA

• Transaction Junction

• Yoyo

In order to determine if a QR code is supported by Zapper, it should be sent for decoding so that the value can be verified against the regex below:

^((.*zapper\.com.*)|(.*\.wigroup\..*)|(.{2}\/.{4}\/.{20})|(.*payat\.io.*)|(.*(paynow\.netcash|paynow\.sagepay)\.co\.za.*)|(SK\-\d{1,}\-\d{23})|(\d{20})|(.*\d+\.zap\.pe(.*\n?)*)|(.*transactionjunction\.co\.za.*)|(CRSTPC-\d+-\d+-\d+-\d+-\d+))$

The code should be trimmed before performing the regex match.
