And I also have a small, somewhat related follow-up question:

When we send these events, we would like the custom metric be called something like "Viewed Product - TrackBee" or "Placed Order - TrackBee” (so following Klaviyo's own naming scheme, followed by our company name). Will this cause any problems? On this page https://developers.klaviyo.com/en/docs/guide_to_integrating_a_platform_without_a_pre_built_klaviyo_integration it mentions that naming them incorrectly will cause some things to not work, but it's unclear if the name has to exactly be "Viewed Product" or if it only needs to start with that. For example I've seen Elevar (a different tracking SAAS) also name their Klaviyo metrics "Viewed Product - Elevar SS".

Hello @TrackBee 

You can pass additional any additional info in the event. here is an exmaple:

"type": "event",
    "attributes": {
      "properties": {
        "newKey": "New Value",
        "newKey-1": "New Value"
      },

}

Regarding the metric, If you are creating your own metric for Viewed Product, Ordered Product then keep in mind that out of the box metrics won’t be updated.

Another limitation is that you can only update one metric in a call.
