Spawn Bulk Profile Import endpoint is creating profiles, but not adding them to the list.

Hey all,

We have a service that’s syncing external contacts to Klaviyo. It’s currently using the legacy api endpoint:

POST /api/v2/list/{list_id}/members (documentation)

I am trying to migrate to the new API (as per this documentation) to following endpoint:

POST /api/profile-bulk-import-jobs (documentation)

The endpoint is working as expected in terms of creating/ updating profile, however it’s not adding the profiles to the desired list

Any help would be appreciated. Curl request below:


Curl request:
