# Company changes (registered / changed / ceased) for a CVR-nummer list or a kommune

`GET /v1/overvaagning/cvr/haendelser`

## Request

- Base URL: `https://api.grundfast.dk`
- URL: `https://api.grundfast.dk/v1/overvaagning/cvr/haendelser`
- Auth: one of:
  - HTTP bearer
  - API key in cookie `gf_session`

The change feed behind the `cvr.*` webhooks: companies the weekly CVR harvest found registered (`cvr.oprettet`), changed on a served field (`cvr.aendret`: navn, status, ophoersdato, virksomhedsform, adresse, kommunekode, kommune, branche) or ceased (`cvr.ophoert`: status ophørt / tvangsopløst, or an ophørsdato appearing), in `sekvens` order. Give at least one of `cvr_nummer` or `kommunekode` (comma-separated lists allowed; a kommune also matches companies that moved out of it). Page with `efter` = the previous response’s `naeste_efter`. The corpus is reloaded weekly, so a change appears up to about a week after CVR registered it; changes are kept for 35 days. An empty page means "no changes" only up to `meta.feed.senest_opdateret`, and only while `meta.feed.forsinket` is false.
