Filtering Duplicates in Webhook Data Using Unique IDs

Hello team, I am pulling in Data with a webhook. Is there a way to omit data that is duplicated from coming in with that webhook. I have unique ID's that I can use the omit this data but am not sure how to edit that within the webhook. Is there a way to filter these duplicates out. I don't want to be wasting any credits on these webhooks. Thanks
