The APPS Python API serves to simplify automation of submission of data to, and fetching of positioning from APPS. To use the API, you must point it to your settings file that contains your authentication credentials and other configuration parameters.

To install the api via pip:
pip3 install https://pppx.gdgps.net/static/lib/gdgps-apps-1.0.0b2.tar.gz

Detailed source level documentation of the API can be found here

Once APPS is installed, you can upload files easily: apps_upload *.rnx.bz2

And do many other apps related operations using the apps_* commands.
