Universes

Create Secret

Changed on Oct 20, 2026

Creates a new secret. A maximum of 500 secrets per universe is allowed.

Only the owner of the universe can create secrets. For group-owned universes, only the group owner or authorized members can create secrets.

To encrypt the secret:

Get the public key using the Get Public Key endpoint
Encrypt your secret using LibSodium sealed box
Base64 encode the encrypted content

Include the key_id from the public key response in the request.

For an example, see the Secrets store guide.
