ga4refundR

R function for ecommerce refunds in Google Analytics 4.

Google documentation isn't great for ecommerce refunds. There's a lot of trial and error in figuring out exactly how refunds work and the limitations they have.

This package essentially automates the refund as specified in the GA event builder

Functions

There is just 1 function at present, simple_refundR_fun.

This function will add a financial credit against the entire transaction amount.

This credit will appear against the specified transaction id, but will appear time-wise in the present. This is an important consideration as the refund may appear in a different reporting window from when the transaction was first recorded. Events can only be backdated 3 calendar days.

Function arguments

• api.secret generated within the GA4 web console
• measurement.id the GA4 measurement ID for the property recording ecommerce transactions
• client.id GA client_id - you can find your GA client id in this article
• t.order.id the id of the order you want to refund
• t.value the previously recorded transaction value but expressed as a negative numeric value eg. -29.99
• t.currencythe ISO currency the transaction was in eg. "USD"

Pre-requisites

The httr package. Run install.packages("httr") to install or follow the prompts in RStudio if / when asked.

Future development

• Wrap into an R package - near-term
• Add support for products - long-term
