How to unsubscribe a user from all lists via the API?

Question

We’ve got hundreds of mailing lists, so cannot loop around each one unsubscribing hoping they’re in it.

How can we get a list of Lists that the user is subscribed to, to unsubscribe them via the API

or

An API call that unsubscribes the user from all lists they’re members of?

Thanks

Hey @owen_fnatic,A user once unsubscribed from a list gets unsubscribed everywhere since that detail gets attached to his profile in Klaviyo and consent is removed globally for that user.The best way to bulk unsubscribe users from mailing lists is to create a separate list of users that you want to unsubscribe and then unsubscribe them all from that list via API. Once that is done, they will be unsubscribed from everywhere and get suppressed.curl --request DELETE \     --url 'https://a.klaviyo.com/api/v2/list/LIST_ID/subscribe?api_key=API_KEY' \     --header 'Content-Type: application/json' \     --data '{     "emails": [          "email1@example.com",          "email2@example.com"     ]}'
