Returns the existing record when a physical nexus is created twiceNexus

Breaking changeNexus

Creating a physical nexus for an organization, country, state and category that already has one used to fail with 409 Conflict. It now succeeds and returns the stored record unchanged: the dates and address in the request are not applied. On v1 and the Partner API the response is 200, the same as for a new record. On the 2026-07-21 release it is 200 for an existing record and 201 for a new one.

Endpoints

What to do

Stop relying on 409 to detect an existing record.
To change an existing record's dates or address, update it: PUT /v1/nexus/physical_nexus/{physical_nexus_id} on v1, or PATCH /physical-nexus/{physical_nexus_id} on the 2026-07-21 release.
