An advertiser notices that the Pinterest tag is collecting far more events than its API for Conversions 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 the Pinterest tag and the API for Conversions report similar numbers, it's crucial that they use the same event IDs for corresponding events. This allows Pinterest to deduplicate events accurately, preventing double-counting when both methods track the same user action. If event IDs differ, Pinterest treats them as distinct events, leading to inflated counts from the tag. Using multiple event IDs for multiple events is correct practice, but doesn't address the deduplication issue between the tag and API. Enabling Enhanced Match improves attribution accuracy but doesn't resolve discrepancies caused by mismatched event IDs. Deleting the API for Conversions would remove a valuable, more reliable tracking method and is not a solution for reconciliation.
