URL shortener
The system also offers a URL-shortener to shorten a URL that can be distributed easily or that can be used to generate a QR code. The lesser the amount of characters in the URL, the cleaner the QR code will be.
For instance, the next URL:
https://en.wikipedia.org/wiki/The_quick_brown_fox_jumps_over_the_lazy_dog#Cultural_references_in_several_different_languages will generate a QR code like this:
When we use the URL shortener to convert the previous URL to a short URL, we get this URL: https://spbl.eu/Wv0k99cbB that will generate a much more readable QR code like this:
When the last barcode is printed, the chance is small that errors occur when it is scanned by a QR reader.
The connection to the URL shortener API is a secure connection that is protected by IP address (optional), an Extended Validation SSL certificate and a username and password combination that must be supplied as ‘basic authentication’ header.
To create a connection, the following things must be arranged:
| SUBJECT | DESCRIPTION |
|---|---|
| IP Address | The IP address(es) of the server that connects to the PayByLink system must be supplied to the PayByLink or Entity administrator. He can enter these addresses in the system so that connections that are created form other IP addresses will be refused. |
| Username Password | An API user must be created within the PayByLink system with its own unique username and corresponding password. These values must be used to create a secure connection. |
