To discover dimensions and metrics in GA4 with Claude or ChatGPT, connect your Google Analytics 4 account to PaidSync.ai and ask the assistant to list the dimensions and metrics for my property, which tells you what you can ask a report to include. It reads only.
A report can only use names that the property knows. One read tool returns all of them, custom definitions included:
get_ga4_metadata lists the dimensions and metrics available for a property, so you know the exact names to request.list_ga4_custom_dimensions shows the custom dimensions already defined on the property.list_ga4_custom_metrics shows the custom metrics already defined.get_ga4_metadata, list_ga4_custom_dimensions and list_ga4_custom_metrics only read your account. That is the full set you need to discover dimensions and metrics.
| Tool | What it does |
|---|---|
| get_ga4_metadata | Lists every dimension and metric |
| list_ga4_custom_dimensions | Shows custom dimensions |
| list_ga4_custom_metrics | Shows custom metrics |
Search the answer for the topic you care about, such as ecommerce or events. The assistant can filter a long list down to the names that matter.
These steps use Claude to discover dimensions and metrics. PaidSync.ai also works in ChatGPT, and the prompts are the same.
