Prerequisites
The barcode generator requires a source attribute and a target attribute in Akeneo. E.g. An attribute containing the QR data should exist, as well as an image attribute to store the generated QR code.
Setting up the task
Navigate to the task overview in the middleware application. In the right-hand corner click + CREATE. Choose a label of your choice, a unique code to identify the task is generated automatically (but can be overwritten). As task type, choose generate_qrcodes.
You will be redirected to the edit task page. In the section Parameters you will be able to set a source attribute in the data attribute input field, and a destination attribute in the attribute to store QR code input field. Optionally, you can define an image format, colors and dimensions.
Finish the configuration of the task by scrolling down to the Schedule section and - optionally - providing a frequency of the task to run (this gets translated to a CRON configuration. More information: https://en.wikipedia.org/wiki/Cron).
Running the task
The task can be executed manually within the middleware application by navigating to the task, followed by clicking run in the top section.
You are redirected to the operation overview where the logs will be available as the operation goes through the process.
The result is a generated QR code for each product that meets the criteria. If the task is scheduled, QR code images will be added automatically to Akeneo.
