How to Add NCPurchase ROAS in Ads Manager

If an event name is marked Blocked in that list, do not build on it. Stores in restricted categories (health, wellness and similar) sometimes have NCPurchase / RCPurchase blocked by Meta, and a custom conversion built on a blocked event reports zero forever rather than showing an error. NC_Target / RC_Target are available on those stores for exactly this reason. Whether a name is blocked can change over time, so if a column you built suddenly reads zero, check this list again.

1. Verify Custom Events: NCPurchase and RCPurchase

In the "Overview" tab of your pixel (Dataset), you will see alerts for any unconfirmed events. Click the "Review" button.

If no alert appears in the "Overview" tab, the same list is reachable from the "Settings" tab: scroll down to "Data restrictions" and click the "Review" button under "Manage event blocking".

Please select both "NCPurchase" and "RCPurchase" within this dialogue box, and then proceed by clicking the “Next” button located at the bottom right-hand corner. If your dataset uses the NC_Target / RC_Target names, select those two instead. Events already marked Blocked cannot be confirmed here — skip them and use the other pair.

Select the option "Confirm the custom event" and then click the "Confirm" button; this will finalize the confirmation of the previously selected events.

3. Create NCPurchase ROAS Metric

Proceed to the “Ads Manager” dashboard, and from the left side menu, navigate to “Campaigns.”

Click text button “Create custom metric”

In this dialog, click the dropdown labeled “Select Metric,” then filter by “NCPurchase,” and select “NCPurchase Conversion Value.” Naturally, if the conversion created previously bears a different name, you must choose according to the name you designated.

Next, click the division sign, and then select another metric by clicking “Select Metric,” where the metric is “Amount Spent.” This will yield a formula as illustrated in the following image. And click “Save changes”.

Thus, you will see the metric within the category of “Custom Metrics” and subsequently check it.

Finally, you can see the column labeled “NC ROAS” within the table.

Create custom conversion of RCPurchase

You can create a custom conversion for RCPurchase by referring to the NCPurchase created earlier — using RC_Target in place of RCPurchase if that is the name your dataset uses.

If you want to create other metrics, adjust the formula and format in the creation dialog.

Here are some common metrics：
