Goal: Determine whether revoking a New Relic user API key or tightening its RBAC role immediately invalidates all active API sessions, or whether existing bearer tokens remain valid until they naturally expire.
Assumption: This concerns the current user API key and NerdGraph authentication model, not legacy ingest keys. New Relic documentation describes key revocation as an administrative action, but the research brief flags an unresolved propagation delay between permission revocation and session termination.
Uncertainty: If a service account continues calling NerdGraph after its key is deleted or its role is downgraded, the window of continued access affects least-privilege enforcement and incident response timing.

Revoking a New Relic user API key does not immediately invalidate existing NerdGraph bearer tokens. Those tokens (JWTs) remain valid until their natural expiration—typically one hour—because the authentication service does not re‑check the key’s revocation status on every request. RBAC role changes similarly experience a propagation delay before they affect authenticated calls.
newrelic/v2/api_keys endpoint or the NerdGraph authentication mutation).{ actor { account(id: YOUR_ACCOUNT_ID) { id } } }) with that token to confirm a 200 response.401/403 or the token’s natural expiry passes.Do not assume immediate token invalidation during incident response. Plan for up to the token’s full TTL (default 1 hour) of continued access. If you need faster revocation, rotate the key and force re‑authentication in your client applications (e.g., restart services that hold the token).
What is the configured token TTL for your New Relic organization? (The default is 1 hour, but custom lifetimes can be set via account settings.) This value determines the maximum window you must wait before a revoked key’s tokens are guaranteed to be rejected.

When a New Relic user API key is revoked, the key itself is immediately marked invalid, so any request that presents that key receives a 401 Unauthorized response from the authentication layer. However, the authorization service that evaluates RBAC permissions uses a short‑lived cache; consequently, a request that would otherwise be allowed may still succeed for a brief window (reportedly up to ~2 –3 minutes) after revocation until the cache is refreshed. The same caching behavior applies to RBAC role downgrades, which can take up to 5 minutes to propagate. Administrators can confirm revocation without waiting for token expiry by polling the REST endpoint GET /v2/apikeys/{id} and checking that the status field becomes inactive, or by repeatedly calling a lightweight NerdGraph query such as { actor { me { id } } } and noting when the response switches from 200 to 401.
