# Set VPC endpoint restriction

`POST /projects/{project_id}/vpc_endpoints/{vpc_endpoint_id}`

Sets or updates a VPC endpoint restriction for a Neon project. When a VPC endpoint restriction is set, the project only accepts connections from the specified VPC. A VPC endpoint can be set as a restriction only after it is assigned to the parent organization of the Neon project.

## Errors

default

General error

This endpoint can return the standard Neon API error response.

Response fields

- `message` Required. Human-readable error message.
- `code` Required. Machine-readable error code.
- `request_id` Optional. Request identifier for debugging. You can provide one with the `X-Request-ID` header.

Retry guidance

If no response is returned, the request may still have reached the server. This is why retry safety depends on the method and status code.

Idempotent methods (`GET`, `HEAD`, `OPTIONS`) are generally safe to retry after a network error or timeout. Non-idempotent methods (`POST`, `PATCH`, `DELETE`, `PUT`) can change state, so avoid automatic retries unless your workflow can tolerate duplicate effects.

Responses with `423 Locked` or `503 Service Unavailable` are safe to retry. `423 Locked` means the resource is temporarily locked, usually because another operation is in progress.
