GA4 offers several versions of these dimensions, and picking the wrong one means your Whatagraph table won't match what you see in GA4. The two you want are the session-scoped and first-user-scoped variants; these are what GA4's standard Acquisition reports are built on.
The plain "Default Channel Grouping" and "Source / Medium" dimensions are also available, but they're event-scoped, meaning they're used for attribution and conversion path analysis, not the channel or traffic acquisition views most users are comparing against.
Source / Medium table
Step 1. Add a table widget to your report.
Step 2. Click on the widget and set the dimension to "Session Source / Medium" or "First User Source / Medium".
Use Session Source / Medium to match GA4's Traffic Acquisition report. It shows the source for each individual session.
Use First User Source / Medium to match GA4's User Acquisition report. It shows the source that first brought a user to your site.
Avoid the plain "Source / Medium" dimension. It's event-scoped and won't match the data in your standard GA4 dashboard.
Tip: To show only a specific source or medium, click on the widget, scroll to the Filters section, and add a filter on your chosen dimension. For instance, set "Session Source / Medium" "Contains" "CPC" to isolate paid traffic.
Default Channel Grouping table
Step 1. Add a table widget to the report.
Step 2. Click on the widget and set the dimension to "Session Default Channel Grouping" or "First User Default Channel Grouping".
Use Session Default Channel Grouping to match GA4's Traffic Acquisition report.
Use First User Default Channel Grouping to match GA4's User Acquisition report.
Avoid the plain "Default Channel Grouping" dimension. Like "Source / Medium," it's event-scoped and is used for attribution modelling in GA4, not the standard channel views you're likely comparing against.
