Meta Definitions

The data pushed to your Meta pixel will have the following fields set for each event sent to the Meta pixel.

Field	Then…
Action Source	Always set to `website`
Event ID	Always set to the unique value `{SEQ}:{version}`
Event Time	Time of the conversion or event
Currency	Always set to `USD`
Order ID	Set to `{SEQ}`, the Katalys Sequence Number used to reference conversions or events within KMP
Event Name	An Event Postback will be dynamic, based on category. A Conversion Postback will create a `Purchase` event.
Event Value	Partner or Advertiser Event Postback: No value is set for events. Partner Conversion Postback: When conversion is billable, set to the payout value of the conversion. When conversion is last-click, set to $0. When conversion is rejected, set to $0. When conversion is partial-attribution, value is missing. Advertiser Conversion Postback: Configurable, by default set to the “Order Value”. Can alternatively be set to the Katalys Commission value if you modify the setting on the Postback-Edit screen. If an event was previously reported with a >$0 value, and must be adjusted to $0, then the event might have a negative value.
