# Delete IAM credential

> **DELETE** `https://api.us.nylas.com/v3/iam/principals/{principal_id}/credentials/{credential_id}`

Source: https://developer.nylas.com/docs/reference/api/iam-credentials/delete-iam-credential/

Requires `iam.credentials.delete` on an active principal bound to the authenticated organization. Authenticate with an active, unexpired IAM credential of type `api_key`. Application API keys (including legacy API keys) and provider OAuth tokens cannot authorize IAM management endpoints. Use an existing IAM credential with these permissions, or [create your first management credential in the Dashboard](/docs/v3/auth/nylas-iam/manage-principals-with-api/#create-a-management-credential-in-the-dashboard).

Permanently deletes the credential. It can no longer authenticate. A successful response contains request_id and no data.

**Authentication:** IAM_API_KEY
