Do I need to create a new custom event for each pixel to track specific actions like "add to cart" or "initiate checkout"?

Enabling certain events such as "add to cart" or "initiate checkout" requires creating a custom event and adding scripts.

No, you do not need to create a new custom event for each pixel to track the same event. If you have already created a custom event for an event (e.g., "add to cart") and added the necessary script, you do not need to repeat this process for other pixels.

In summary, you only need to create and add a custom event once for each type of action you want to track. If you have already added a custom event for "add to cart," you do not need to do it again for other pixels.
