Total Initiate Checkout is now available in the Analytics report.

The Analytics report now supports Pinterest's native TOTAL_INITIATE_CHECKOUT metric at the campaign and ad-group reporting levels. It counts initiate-checkout events attributed to interactions with your ads, using the attribution windows and conversion reporting time configured for the extract.

The metric appears as Conversions (Initiate Checkout) and is stored as total_initiate_checkout. Adding it to an existing extract does not populate older rows automatically. Backfill earlier dates within the extract's configured history window; dates for which Pinterest no longer provides reporting data cannot be recovered.
