# /v1/project/{}/invoice/{}/{} stops working

Calls to /v1/project/{id}/invoice/{id}/{id} on Aiven API stopped working on July 16, 2026.

The endpoint /v1/project/{id}/invoice/{id}/{id} was removed on July 16, 2026. Calls sent to this path fail after that date. Aiven API previously deprecated the route in favor of an organization-level equivalent.

## What to use instead

Call /v1/organization/{organization_id}/invoice/{invoice_number}/pdf instead using the organization-level API.
