# NOT PARENT PROJECT

Canonical page: https://docs.ovok.com/errors/not-parent-project

**HTTP 403.** Stable Problem Details type: [`https://docs.ovok.com/errors/not-parent-project`](https://docs.ovok.com/errors/not-parent-project).

## What this means [#what-this-means]

This billing operation must be made from the parent project that owns the sub-project's billing. Clients should branch on `type` and `status`, not on human-readable `detail` text.

## Troubleshooting [#troubleshooting]

Check the project hierarchy and use an authorized administrator session for its billing parent. Compare the request with the relevant endpoint's documentation and confirm the authenticated project and environment. Record the request path and `traceId` before escalating; the identifier lets an administrator find server-side context without sharing credentials or patient data.

## Retry safely [#retry-safely]

Correct the request, configuration, access or project state described above before retrying. Repeating an unchanged request will normally return the same error; for writes, check whether the first attempt changed state before sending it again. Follow endpoint-specific idempotency and concurrency guidance. Do not retry in a tight loop or use a broader permission or project setting to bypass the check.

## If the problem persists [#if-the-problem-persists]

Share the HTTP status, problem `type`, request path, response timestamp, and `traceId` with your administrator or support contact. Remove access tokens, provider secrets, and sensitive patient data from the report. The [Error responses guide](/errors) explains the response fields, while the [machine-code registry](/errors/machine-codes) lists every endpoint-specific type audited for this release.
