We want to use the shipping label that has an extra removable tab at the top.  Fedex wants to see

"label_size": "4X6.75_TRAILING_DOC_TAB"

We are using the Easypost API and it doesn’t support this size, the closest is regular 4x6.  Easypost supports it but the API doesn’t.  Has anyone managed to use this label size with any of the carrier integrations?

The list of label options is hard coded on the plugin level and can be extended via a Customization.

I would recommend creating a 'How To' support request case with our Dev Support team to help guide you in the right direction.

One of our clients actually just completed this and asked to shared it with our community, in case anyone else needs it (thank you Mr. Alan Fang!) 

What to extend:

  • Screen: CS207700 — Carriers
  • Graph: CarrierPluginMaint (via a PXGraphExtension)
  • DAC: PX.Objects.CS.CarrierPluginDetail
  • Field to target: the Value field's dropdown, on the

  settings row where DetailID = "LABEL_SIZE"

Values to add to that dropdown:

  • 4X6.75_LEADING_DOC_TAB
  • 4X6.75_TRAILING_DOC_TAB
  • 4X9_LEADING_DOC_TAB
  • 4X9_TRAILING_DOC_TAB
