Samsara provides the ability to integrate with Transfinder. The integration allows you to view bus information in Transfinder, and also imports routes from Transfinder into Samsara.
You can contact your Transfinder representative in order to set up Samsara as your GPS provider, and to retrieve the Samsara Vendor ID for the Samsara-Transfinder integration.
Afterwards, to enable the integration, navigate to the admin dashboard, and into the Settings > Integrations tab. From here, you can enter in your Transfinder credentials.
As always, feel free to contact Samsara Support if you need help finding the right information or have any questions about the integration.
