To connect your marketing tools and get their reporting data into to Funnel, select Data sources in the left-hand navigation bar:
Hit "+ Connect Data Source" to open a dialogue listing all of Funnel's connectors.
Find the platform you want to connect to and follow the instructions. How to connect may vary depending on how Funnel integrates with each platform.
If you can't find the platform you're looking for and are on a price plan with data guarantee, you can file a data request at the bottom of the dialogue. There, you'll also find self-service tools to import data that you have access to.
Each data source you set up will show up on the Data Sources view.
