# Request a principal’s approval to delegate an existing case

Confidential approved partner client authentication required. The one-hour, single-use hosted approval link creates the same case-bound delegate grant as ordinary OAuth. Approval binds the current case membership and side; each token use rechecks that membership. Approval or denial consumes the link. A new case is never created.

## Errors

Read the response status and stable error code. See [errors](https://peoplescourt.ai/docs/api/errors.md) and [rate limits](https://peoplescourt.ai/docs/api/rate-limits.md) for recovery. Refresh the resource before resolving a state or digest conflict.

## Idempotency and retries

- For throttling, honor Retry-After when present. Back off on retryable server failures.
- The request is accepted only when its credential, authority, case state, and resource preconditions are satisfied.

## Request examples

Use `https://peoplescourt.ai` with the test credential issued for your integration.
