An advertiser notices that the Pinterest tag is collecting far more events than its Conversions API when looking at the Event History page in the Conversions tab. What should the advertiser do to make sure both conversion tracking solutions report a similar number of conversions?

To ensure both the Pinterest tag and Conversions API report similar conversion numbers, you must use the same event IDs for corresponding events across both tracking methods. This allows Pinterest to deduplicate events accurately, preventing double-counting and providing a unified view of conversions. If event IDs differ, Pinterest treats them as distinct events, leading to inflated numbers from the tag or API. Deleting the API would remove a valuable, more reliable tracking method. Using multiple event IDs for multiple events is correct practice, but not the solution for discrepancies between existing tag and API events. Enabling Enhanced Match on the Pinterest tag improves matching accuracy but doesn't resolve discrepancies caused by mismatched event IDs between the tag and API.
