API returning incorrect transactionsPerSession and transactionRevenue data when a custom filter pagepath added

I am using the API to get analytics data display, For that first I am checking data and parameters in this ga-dev-tool. have checked both ways in ga-dev-tool.

When I try without pagepath its works properly and I get data of transactionsPerSession and transactionRevenue. But when I try with pagepath in the same way it’s not working and giving 00 for all these 2 values.

Answer

If you want to get transection related data from API

Then You have to pass ga:landingPagePath

Instead of ga:pagePath in dimension Filter

Let me know if you still getting incorrect transactionsPerSession.
