Technical details for user interfaces to the Post-Labelcenter
In this section, you will find technical details, descriptions and example files for our two interface options, which are polling and webservice.
Polling
Polling is an activity where a service is installed that checks a previously defined folder for import files. These files need to have a certain structure (columns, separators, etc.). If such files exist in the import directory, they will automatically be imported into the Post-Labelcenter and shipping labels will either be printed directly or be made available in PDF format for download.
Webservice
Our webservice gives you the option of making a request in the Post-Labelcenter to create items, import addresses, cancel items, create a daily balance, etc. All requests are transferred as SOAP requests. When importing items, either a PDF or a ZPL2 String will be transferred in the response as a Base64 String if needed. These can be directly forwarded to a laser or label printer.
In addition, during the item import, the item number is also transferred in the response.
