When using both the Pinterest tag and the Conversions API, how should you handle event deduplication to prevent double-counting?

To prevent double-counting conversions when using both the Pinterest tag and the Conversions API, you must use the same Event ID for the same event across both systems. Pinterest uses this Event ID to identify and deduplicate identical events, ensuring that each conversion is counted only once, regardless of whether it's received via the tag or the API. Turning off event tracking in one system would lead to incomplete data. Using different Event IDs would cause Pinterest to treat the same event as two separate conversions, leading to inflated metrics. Deduplication is crucial for accurate measurement and optimization.
