Hey @Raj121 ,
Since you mentioned that you have set up your UTM parameters correctly and your sales are still not attributed to Facebook ads, you might want to check out Report Pundit. If you’re open to using a reporting tool, we can use the “referral site” and “landing site” fields to help you attribute sales.
We offer a 14-day free trial, so you can check if it fits your needs. Please feel free to ask if you have any questions.
Thanks!
