Stopped workingSubscribe to Hetzner Cloud APIShare
On July 1, 2026, the Hetzner Cloud API removed the datacenter body parameter from POST /v1/primary_ips. Calls specifying this parameter fail since that day. The property was previously deprecated in both requests and responses for Primary IPs.

Send location instead of datacenter when creating a Primary IP.
In Hetzner Cloud API's words
We deprecated the datacenter property in the request body and response of Servers and Primary IPs. The removal will happen after 1 July 2026.
