On execution of a Twitter Tailored Audience offer, if the offer's Mode of operation was set to one of Update or Delete, the specified action is performed in respect of the Tailored Audience selected at the offer. A runtime validation error is raised in the event of attempting to execute using a channel other than the channel specified at the offer.
If the offer's Mode of operation was set to Add, a new Twitter Tailored Audience is created. The new Tailored Audience's name is accordant with the offer's Tailored audience custom name property. Users, sourced from RPI, are uploaded to the new Twitter Tailored Audience.
