# Rotate a credential invitation code.

Replaces the code of a pending invitation, resets failed attempts, and sets a new expiry from the requested TTL.

Rotation is deliberately non-idempotent: every successful call invalidates the previous code and returns the only current plaintext code. DeepCredentials does not email the replacement. If a rotate response is lost, rotate again until your system receives a response, then deliver that returned code.

  - `status` (string, required)
    Current invitation lifecycle state.
    Enum: "pending", "redeemed", "expired", "revoked"

  - `reference_id` (string)
    Optional correlation identifier from your system; echoed on the resource.

  - `offer_validity_seconds` (integer)
