Adding birthday field to facebook conversions

I integrated my Acuity and Facebook conversions for Send Purchase Event. However, there is no field for Date of Birth. How do I add this?

Hi @AES TCC,

Is there a "Date of Birth" field in your Facebook Conversions account that doesn't appear in the "Send Purchase Event" action step? Could you please share a screenshot of the same?

We understand that you receive the Date of Birth field in the trigger step, but that's not what we need. You want to pass this Date of Birth to Facebook Conversions, right? Please share a screenshot showing that it is present in your Facebook Conversions account.
