Facebook Conversion API - Duplicate Server-Side Events Issue

Hello everyone,

I’m setting up Facebook Conversion API to improve the data rating on Facebook. To achieve this, I’m using Data Tag on the Client Side.

However, I have a concern: all my server-side events are firing twice—one event is collected via Data, and the other via Collect.

  2. If deduplication is already handled, will Facebook keep the event with the most complete data, or will it be overwritten by the incomplete one?

I appreciate any insights or best practices you can share. Thanks in advance! :rocket:
