Data integration between SARA R4 Sparkfun and ThingsBoard plataform

Hello everyone. Please help me.
Do you have a tutorial or example for data integration between the SARA R4 LTE Sparkfun board and the Thingsboard platform?
The Sparkfun example is aimed at the Hologram platform, but I need the data exchange to be with the ThingsBoard. Any help will be welcome.
Thanks!
