Installation & Use

Once an order is processed, the email address associated with the order will receive an email containing a unique URL for the Dynamic Barcode Generator Service. You may test this URL by copying and pasting the full URL into a web browser. Load the page and a default barcode image will be created.

For example, clicking creates a demo barcode image. This unique URL should be used in place of the demo URL and implemented as described in the Streaming Barcode Implementation section of the Barcode Server for IIS manual.

Customizing the Dynamic Barcode Generator

The Barcode Generation SaaS may be customized according to the available parameters.

  • The Barcode Generator is easily implemented, as described in the Streaming Barcode Implementation section of the Barcode Server for IIS User Guide.
  • The data encoded may be changed by adding ?D= to the end of the URL, for example:
  • Properties may be changed by adding &PropertyName= to the URL. For example:
    NOTE: IDAutomation does not recommend changing properties unless the default values must be changed.
  • To transition from the free/demo version to the purchased version, simply replace with the unique URL provided via email upon order completion.
  • SSL encryption is enabled by changing "http" to "https". For example:

Slow Performance when Generating Multiple Barcodes:
