Delete all Custom Audience User using Facebook API

Question

Hi everyone I have a problem in Facebook Marketing API, I wan't to delete all the custom audience without uploading the same email again, all I want is to just delete every User/people from the Custom Audience and upload a new one. I already read the documentation (https://developers.facebook.com/docs/marketing-api/reference/custom-audience/users#Deleting) but unfortunately can't find a solution .

Answer 1

The only way I have found that this can be done is by doing a mass delete with either all external ID's or Emails.

After deleting all users, it's a simply matter of adding users back to the audience.

Seems far from ideal, but from what I can tell there is no quick "Delete All" type function.
