Hi Manychat Team,

I noticed Manychat is using an old version of the Klaviyo API (V2). Klaviyo's now on V3, which adds contacts more efficiently and ensures proper consent and double opt-in.

Klaviyo said:

I've had a look at API logs and can see the inbound for ManyChat, it looks like it's using an outdated API of ours (v2, we are now using V3) and the API are they are using /members is essentially adding people to the list like uploading a CSV, doesn't look like consent is provided and double opt-in won't be triggered using this API. You would need to contact ManyChat to see if they are going to update their app and if they are going to provide consent when adding contacts to a list. 

Can you please update the integration to use Klaviyo's API V3? This would really help improve compliance and make things smoother for everyone.

Thanks a bunch!
