Custom Barcodes
Custom Barcode Functionality¶
With the provision of internal and external barcode support, a lot of potential use-cases are already supported directly by InvenTree.
However, if further customization is required, or a bespoke barcode workflow which is not supported already, then this can easily be implemented using the plugin system.
A custom barcode plugin can be used to (for example) perform a particular action when a barcode is scanned.
Scanning a Barcode¶
To scan (process) a barcode, the barcode data is sent via a POST request to the /api/barcode/ API endpoint.
Barcode Scanning Priority¶
When a barcode is scanned (sent to the /barcode/scan/ endpoint), each available "plugin" is checked to see if it returns a valid result for the provided barcode data. The first plugin to return a result prevents any further plugins from being checked.
The barcode is tested as follows, in decreasing order of priority:
Plugin Loading Order
The first custom plugin to return a result "wins". As the loading order of custom plugins is not defined (or configurable), take special care if you are running multiple plugins which support barcode actions.
