This group manages the link between a profile and a status. To create or configure the status definitions themselves, use the Status endpoints.
Adding statuses is additive
POST /v3/profile/status/batch.json adds the handles you send and keeps the statuses each profile already holds. The endpoint merges your handles with the profile’s existing statuses before saving, so existing statuses are preserved.
This is the correct endpoint for adding a status to many profiles without disturbing their other statuses.
Request shape
Send one entry per profile. Each entry needs theprofile_id and the handles to add:
202 with a batch_id. Poll the batch with that id to track progress.
