Hi @efferre68,
Thanks for sharing this question with the community.
If I understand your question correctly, you’re asking if Klaviyo can send a “final acknowledgement” email to users who were added to Klaviyo’s “Profiles” tab via the API? If that is the case, the answer is yes. There are a few different ways to achieve this. The first is to use our Lists & Segments API to add all of these users to a list. You can add them to the list without consent using the members endpoint. Or you can add them to the list with consent already included using the subscribe endpoint. Next, create a list-triggered flow and add the final acknowledgement email to that flow. So in effect, anyone who joins that list, will receive that email.
Alternatively, within the payload of the API call, you can include an additional property, for example $source = OneTrust. Then, build a segment like the following: Properties about someone > $source = OneTrust. Then, create a segment-triggered flow based on that property including the final acknowledgement email. Anyone who joins that segment, will receive that email.
I hope this helps answer the question. If I misunderstood, please feel free to clarify.
