Custom Barcode Functionality¶
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.
Builtin Supplier Barcode Plugins¶
InvenTree comes with a few builtin supplier plugins, which handle their respective barcode formats.
Scanning a supplier barcode for a supplied part will link to the corresponding supplier part if the SKU from the barcode could be matched.
The following suppliers (and barcode formats) are currently supported:
- DigiKey (2D Data Matrix code)
- Mouser (2D Data Matrix code)
- LCSC (QR code)
- TME (QR code & 2D Data Matrix code)
